Pech qanday ishlaydi va u o'zini qanday yoqadi va o'chiradi

Ko'pincha biron bir narsaning yomonligini aniqlashning eng yaxshi usuli bu qanday ishlashi kerakligini bilishdir. Agar siz operatsiyalar ketma-ketligini bilsangiz, ketma-ketlikning buzilgan joyini aniq belgilashingiz mumkin. Sizning pechingiz qoidadan istisno emas.

Sizning pechingiz termostat tomonidan ishga tushirilganda, u xavfsiz tarzda o'zingizni yoqib yuboradigan protsedura uchun qofiya va sabab bor. Keyingi safar sizning pechingiz qo'ng'iroqqa javob bermasa, muammo qayerda ekanligini bilib olasiz va uni ta'mirlash sizning mahoratingiz va mablag'ingiz doirasida yoki siz ishlash uchun professional HVAC texnikasi kerak deb qaror qilishingiz mumkin. siz uchun muammo.

Muammoni o'zingiz hal qilsangiz ham, yoki xizmat ko'rsatuvchi mutaxassisga muammoni ko'rsatib qo'ysangiz ham, keyingi munozara sizga vaqt va pulni tejashga yordam beradi.

Ishdan bo'shatish tartibi: zamonaviy majburiy havo pechini ishlatish bosqichlari

Termostat issiqlikni so'raganda, o'choq harakatga o'tib, quyida joylashgan qadamlar va tarkibiy qismlardan o'tib ketadi. Ushbu tarkibiy qismlarning aksariyatini videoda ko'rishingiz mumkin.

  1. Termostat pechning yonishini aytadi.
  2. Induktorli dvigatel ishga tushadi.
  3. Bosim tugmasi bacaning to'g'ri chiqarilishini tasdiqlaydi.
  4. Issiq sirtli ateşleme moduli (agar sizda uchqun ateşleyicisi yoki uchuvchi emas, balki bo'lsa) porlay boshlaydi.
  5. Gaz valfi ochiladi va gaz ateşleme manbai tomonidan yonadi.
  6. Olov sensori gaz yoqilganligini tasdiqlaydi.
  7. Yuqori chegara tugmasi belgilangan haroratga etadi.
  8. Shamollatish vositasi yonadi.
  9. Pech termostatni qondirguncha ishlaydi va uni o'chirishni aytadi.
  10. Gaz valfi yopiladi.
  11. Yuqori chegara tugmasi past harorat darajasiga etadi.
  12. Ventilyator o'chadi.

Yangi o'choq yanada ko'proq qo'ng'iroq va hushtaklarga ega bo'lishi mumkin; eski o'choq minimal bo'lishi mumkin, gaz klapani va termojuft (eskirgan olov sensori kabi). Termojuft yoki olov sensori uchuvchi yoqilganligini tekshiradi va agar u bo'lmasa, asosiy gaz vanasining ochilishini to'xtatadi. Albatta, singan termojuft ham gaz klapanining ochilishini to'xtatishi mumkin.

Termostat

Termostat hamma narsa boshlanadi. Termostat, albatta, faqat haroratga qarab ochiladigan va yopiladigan, isitish va sovutish tizimidagi ma'lum davrlarga quvvat oqimini ta'minlaydigan kalitlarning to'plamidir. Ularni yuqoriga va pastga tebranadigan ko'priklar kabi tasavvur qiling. Ular odatda tuzilgan, lekin ko'prikni yopish va elektr energiyasining o'tishi uchun pastga tushirish mumkin.

Uyingizdagi harorat tushganda, termostat ko'prikni pasaytiradi va issiqlik zarurligini bildirish uchun pechga kuch yuboradi. Xona harorati yana ko'tarilganda, termostat ko'prikni ko'taradi va quvvatni o'chiradi. Konditsioner uchun termostat xuddi shu tarzda ishlaydi, lekin ko'zgu tasvirida, uy juda qizib ketganda ko'prigini yopadi.

Agar uydagi harorat siz termostatni o'rnatgan haroratdan pastroq bo'lsa, sizning termostatingiz kerakli darajada ishlamay qolishi mumkin. Siz buni termostatni qizil va oq simlarga sakrab (bir-biriga tegizish) sinab ko'rishingiz mumkin. Agar pech yoqilsa, sizning termostatingiz muammo bo'lishi mumkin.

Termostatdagi simlar nima qiladi?

Uy tizimidagi simlarning boshqa ranglari rivojlangan funktsiyalar yoki kelajakda foydalanish uchun bo'lishi mumkin.

Simli rangU nimani boshqaradi

Qizil

Qizil kuch uchun. Bu pech tomonidan ta'minlanadigan 24 voltli quvvatga ega. Bu kuch "ko'prik" da qaerga borishni aytmaguncha kutib turadi.

Oq

Oq issiqlik uchun. Qizil va oq simlar orasidagi ko'prik (kalit) yopilganda, termostat issiqlikka chaqiradi.

Sariq

Sariq rang sovutish uchun mo'ljallangan. Qizil va sariq simlar orasidagi ko'prik (kalit) yopilganda, termostat sovutishga chaqiradi.

Yashil

Yashil rang muxlis uchun mo'ljallangan. Qizil va yashil o'rtasidagi ko'prik yopilganda, faqat fan ishlaydi. Hech qanday issiqlik yoki sovutish uchun chaqirilmaydi.

Moviy

Moviy rang - bu firibgar yoki yovvoyi karta. U displeyni kuchaytirish yoki rivojlangan xususiyatlar uchun ishlatilishi mumkin. Odatda, u yana devorga o'raladi va umuman ishlatilmaydi.

Induktorli dvigatel va fan

Induktorli dvigatel va ventilyator itaruvchisi uglerod oksidi (CO) dan xalos bo'lib, bacani chiqarib tashlaydi. Qadimgi tizimlar ushbu gazlarni chiqarish uchun faqat "tabiiy tortishish" ga tayanar edi, ammo induktorlar o'choq tizimiga ajoyib qo'shimcha bo'ldi. Ular bacalarning ishlash muddatini uzaytiradi va bosim o'tkazgichlari bilan ishlatilganda ular CO zaharlanishining oldini olishga yordam beradi.

Bosim o'tkazgichlari

Bosim tugmachasining vazifasi induktor dvigatelining havoni bacadan yuqoriga ko'tarishini tekshirishdir. Agar mo'ri to'sib qo'yilgan bo'lsa, masalan, qushlarning uyasi bo'lsa, bosim o'tkazgichi CO ning uyga kirib qolish xavfini yo'qotish uchun tizimni o'chiradi. Albatta, dvigatel eskirgan va tugmachani qondirish uchun juda sekin ishlayotgan bo'lsa yoki ventilyatordan kalitga shlang siqilgan yoki singan bo'lsa yoki kalit o'zi yomon bo'lsa, bosim tugmachasi ham yopilishi mumkin.

Issiq sirtni yoqish moslamasi

Shunga qaramay, murakkab tizimdagi juda oddiy qurilma. Issiq sirtli ateşleyici, elektr energiyasidan foydalanib, juda nozik bir keramik elementni tashqi ko'rinishiga ko'ra isitadi, tabiiy gaz yoki propan o'tayotganda olovga aylanadi. Issiq sirt yondirgich gazni portga kiritilgandan so'ng darhol yoqish uchun birinchi yondirgich portidagi teshikda joylashgan. Bu jihozda yonmagan gaz to'planishining oldini oladi.

Ba'zi pechlarda uchqun ateşleme deyiladi. Qizil olovli sirt o'rniga uchqun ateşleyicisi gazni yoqish uchun bir qator uchqunlarni hosil qiladi.

Sizning pechingizda issiq yuza yoki elektron yonish borligi muhim emas; eng muhimi, siz chiroqni ishlatishdan qochishingiz kerak. Pilot chiqindi gazni yoqadi; ular isitish mavsumida doimiy ravishda gaz yoqishadi va ba'zi odamlar ularni yil davomida yoqishga ruxsat berishadi.

Bir necha dollarni tejashni xohlaysizmi? Uchuvchini mavsumda ishlatilmaganda pechingizda o'chirib qo'yganingizga ishonch hosil qiling. Kelgusi yilda uni qanday qilib qayta yoritishni o'zingizdan oldin bilganingizga amin bo'ling.

Gaz klapan

Gaz klapani asosan elektron nazorat ostida shlyuzdir. Qurilma issiqlikni chaqirganda va elektron karta kerakli shartlar bajarilganligini tasdiqlaganida, energiya quvuri ëtqizish moslamasiga uzatilib, uning ochilishiga va gazning ateşleyici yoki uchuvchi tomonidan chiqarilishiga olib keladi. Issiqlik aylanishi tugagandan so'ng, valfga energiya kesiladi va vana yana bir marta yopiladi, bu esa burnerlarga gaz etkazib berishni to'xtatadi.

Olov sensori

Olov sensori juda sodda, ammo uy egalariga juda ko'p muammolarni keltirib chiqaradi. Uning yagona vazifasi - issiqlikni sezish orqali gaz yoqilganligini tekshirish. Agar issiqlik bo'lmasa, u blokda xavfli gaz to'planib qolmasligi uchun u gazni o'chiradi. Olov sensori yomonlashganda yoki biroz TLC kerak bo'lganda uni tuzatish oson.

Men o'choq alangasi sensorini tozalashga muhtoj odamlar uchun oddiy asta-sekin ko'rsatma yozdim. Qarang - juda ko'p muammolarni faqat olov sensori yordamida tozalash mumkin.

Video: Olov sensori tozalash

Yuqori chegarali kalit

Yuqori chegarali kalit bir nechta maqsadlarga xizmat qiladi. Birinchidan, u belgilangan haroratga etganligini aniqlamaguncha, u pechning foniyini yoqishdan saqlaydi. Aks holda, fan vaqtidan oldin yonib ketar va har safar termostat issiqlik so'raganida uyga sovuq havo urar edi.

Ikkinchidan, shuningdek, termostatni qondirgandan so'ng, u o'chirgichga qancha vaqt ishlashini davom ettirish kerakligini aytadi. Aks holda, pech o'chirilgandan so'ng kanalda va issiqlik almashtirgichda qolgan issiq havo shunchaki chiqindiga aylanadi.

Va nihoyat, issiqlik almashinuvchisi ma'lum bir yuqori haroratga yetganda, haddan tashqari qizib ketishning oldini olish uchun chegara tugmasi jihozni o'chiradi.

Olovli ventilyator va shamollatuvchi vosita

Oh, nihoyat. Barchamiz uchun issiqlik. Endi barcha datchiklar qoniqtirildi va chegara tugmachasi puflagichga havo yashash maydoniga yuborish uchun etarlicha iliq ekanligini aytganda, u havo oqishini boshlaydi.

Bizning pechning shamollatgichi odatda 120 voltdan foydalanadi va daqiqada 800 dan 2000 kub futgacha bo'lgan joyga suriladi. Ko'pgina shamollatgichlar kondansatördan foydalanishni talab qiladi va agar siz kamar bilan boshqariladigan dvigatel bo'lmasa, to'g'ridan-to'g'ri fanga ulanadigan yarim dyuymli haydovchiga ega.

Tid-Bit: Agar nosozlik bo'lsa yoki jihozning elektr quvvati uzilib qolsa, shamollatgichni yoqish va bir muddat ishlash odatiy holdir. Bu juda ko'p issiqlik borligi va salqinlash uchun chaqirilganligi yoki muxlis tomonidan tezlashtirilishi yoki tarqalishi kerak bo'lgan "yomon gazlar" paydo bo'lishi mumkin.

Chiqib ketish tugmasi

O'zingizning pechingizni bilib vaqt va pul tejang

Umid qilamanki, bu sizning isitish tizimini biroz yaxshiroq tushunishingizga yordam berdi. Siz o'qigan qismlar bilan bog'liq ba'zi muammolarni bartaraf etish g'oyalari va yana bir nechta qismlarga oid maslahatlar.

  • Nosozlik bo'lsa, sizning pechingiz odatda uch marta qayta yoqishga harakat qiladi. Agar uchinchi urinishda u muvaffaqiyatli yonib keta olmasa, u belgilangan vaqt davomida blokirovka rejimiga o'tadi, odatda bir soat. Quvvatni qayta tiklash (uni o'chirish va yoqish) odatda taxtani qayta tiklaydi va jihoz o'tkazib yuborgan taqdirda nima bo'layotganini ko'rsatishga imkon beradi.
  • Jihozdagi ozgina miltillovchi chiroq Rojdestvo bezaklari yoki sizning pechingizdagi kichik diskoteka emas. Ushbu yorug'lik sizni muammoga olib kelishi mumkin bo'lgan Morze kodini miltillashtiradi yoki "Hey, hammasi yaxshi" deb aytadi. Qurilmangizning ichki va tashqi tomonlariga qarang. Siz ko'rayotgan nuqta, nuqta, chiziq, chiziqlar qatori nimani anglatishini aytib beradigan kodli jadval mavjud.
  • Uyingizdagi pechning ba'zi zerikarli tovushlari tinchlanish uchun oddiy va arzon bo'lishi mumkin.
  • Pechingiz haqida g'amxo'rlik qiling, ehtimol u sizga g'amxo'rlik qiladi. Ammo siz jihozni tozalamasangiz va filtrni kerakli darajada o'zgartirmasangiz, pechingiz buzilishi yoki bankingizni buzishi mumkin.

Savollar va javoblar

Savol: Isitgich o'chirilganda va bir necha soatdan keyin qayta boshlanganda qanday muammo bo'lishi mumkin?

Javob: Muammo juda ko'p narsalar bo'lishi mumkin. Pechka kiradigan ushbu "qulflash" ketma-ket 3 marta ishdan chiqqandan so'ng standart hisoblanadi. Afsuski, bu menga muvaffaqiyatsizlik nima ekanligini aytmaydi.

Savol: Kecha texnik xodim chiqib ketib, ba'zi narsalarni o'zgartirib yubordimi va endi issiqlik almashtirgich porlayaptimi?

Javob: Bu issiqlik almashinuvchisi ekanligiga aminmisiz? Salom-limit tugmachasini o'chirmasdan yonib turadigan darajada qizib ketayotganiga shubha qilaman.

Savol: Pech yaxshi ishlaydi, lekin shamollatuvchi o'chmaydi va sovuq havoni puflaydi. Men nima qilaman?

Javob: Aftidan, termostat simlari, ehtimol, qizil rang boshqa simga tegib turgandek, ehtimol qizil rangga ega va fanni doimiy ravishda ishlayapti. Yoki statingiz "auto" o'rniga "fan" ga o'rnatilgan. Bu mening uzoqdan taxmin qilgan dastlabki taxminlarim. Yashil stat simni pechdagi boshqaruv panelidan chiqarib, simlar nazariyasini sinab ko'rishingiz mumkin, so'ngra pechning yana bir tsiklini o'tkazib, uning o'chib-yopilmasligini ko'rishingiz mumkin. Bu hech bo'lmaganda muammo sim / termostat tomonida yoki o'choq tomonda ekanligini sizga aytib beradi. Agar u o'chib qolsa, u stat / sim tomonida. Agar yo'q bo'lsa, muammo o'choqda.

Savol: Mening gaz pechim termostatdagi belgilangan haroratdan 4 ° pastda yonadi. Bu termostat masalasimi?

Javob: Agar har doim ham shunday bo'lsa, u eski stat bo'lishi mumkin va endi unchalik aniq emas, shuning uchun uni almashtirishni xohlashingiz mumkin. Agar yo'q bo'lsa va sizning statingiz yangi bo'lsa, unda u noto'g'ri va ular sizga yangisini berishi kerak.

Savol: Menda Payne pechi bor va induktorli dvigatel va fan doimo ishlaydi. Mening issiqligim tepmaydi va boshlangan kod bosim kaliti ochilmaganligini bildiradi. Men shlangni tekshirdim va u erda hech qanday muammo yo'q. Men pechimni bosim o'tkazgichini almashtirishim kerakmi?

Javob: Ehtimol, kalit yaxshi emas, shuning uchun ha. Arzon bo'lgani uchun, men uni hech bo'lmaganda sinab ko'rardim va agar u ishlamasa, unda texnikani chaqirishim mumkin, ammo agar u sizga ko'p pul tejashga qodir bo'lsa.

Savol: Mening Goodman 96% 2 bosqichli pechim odatda erta tongda termostat issiqlikni chaqirganda boshlanadi. Bir necha daqiqa qizdirilgandan so'ng, pech termostatni chaqirishi qondirilgandek o'chadi. Shu bilan birga, tizim darhol start tsiklini davom ettiradi va termostatni chaqirishi haqiqatan ham qondirilgunga qadar yana bir necha daqiqa davomida isitishni davom ettiradi. Bu yuqori chegarali kalitga o'xshaydimi?

Javob: Menimcha, bunday emas. Menimcha, bu sizning pechning 1-bosqichdan 2-bosqichga o'tishi. Bu, ehtimol bu oddiy funktsiya va umuman muammo emas.

Savol: Nega mening pechim faqat pastki qoralama eshigi o'chirilgan holda to'g'ri ishlaydi?

Javob: Ehtimol, bu jihozga qaytib keladigan havo yetishmayotganligini anglatadi. Ehtimol, kanallar juda kichik yoki birlik juda katta. (Ventilyatorning ma'nosi kanal uchun juda kuchli) Balki vantilatorni sekinroq tezlikda sozlash mumkin, lekin siz ehtiyot bo'lishingiz kerak, u juda sekin emas yoki siz biron muammo bilan boshqasini almashtirib qo'yishingiz mumkin va buning uchun texnologiyaga murojaat qilishingiz kerak bo'ladi. aniq. Afsuski, men bu erda tushuntirish uchun bu qaror uchun juda ko'p narsa bor.

Savol: Shlangi avtomatik rejimda emas, balki rejimda ishlashiga nima sabab bo'ladi?

Javob: Shamollatgich faqat "avtomatik" rejimda isitish / sovutish uchun qo'ng'iroq bo'lsa, yonadi. Fanni "yoqish" rejimi ventilyatorni o'zi yoqadi, lekin issiqlik va sovuqning normal ishlashiga imkon beradi. Agar u issiqlik / salqin "avtomatik" rejimda yoqilmasa, demak, stat yoki taxtada ba'zilari noto'g'ri bo'lishi mumkin.

Savol: Menda Goodman pechi bor va u termostatni 80 va undan yuqori haroratda ushlab tursam yaxshi ishlaydi, lekin agar uni 80 dan pastroqqa aylantirsam, gaz klapani ochilmaydi. Menga yordam bera olasizmi?

Javob: Stat sizning muammoingiz bo'lishi mumkin. Men sodir bo'ladigan boshqa sabablarni o'ylay olmayman.

Savol: Olovli boshlanadi. Uydagi harorat istalgan vaqtga etadi. Keyin brulorlar o'chadi, lekin puflagich puflamoqda. Odatda ventilyator taxminan 100 soniyadan keyin o'chadi, lekin vaqti-vaqti bilan puflashni davom ettiradi va o'chirishning yagona usuli bu sug'urta qutisi. Bu brulorlar ustidagi kalit yoki puflagichdagi kalit bo'lishi mumkinmi?

Javob: Shamollatgich, odatda, bunday noto'g'ri bo'lganda amalga oshiradi. Agar yaqinda hech qanday xato va o'zgartirishlar kiritilmagan bo'lsa, unda taxta yomon ishlayapti va shamollatgichning uzluksiz ishlashiga qisqa sabab bo'ladi. Buni aniq ayta olmayman, lekin men buni ko'rib chiqayapman.

Savol: Pechdagi chegara kalitlari va termojuftlar necha yil davom etadi?

Javob: Har qanday turdagi mexanik qismlarning ishlash muddati har xil narsalarda juda katta farq qiladi. Men faqat ularning kafolat muddatiga xizmat qilishlari kerakligini aytishim mumkin. Kutilayotgan umrga asoslanib, kompaniyalar o'zlarining kafolat shartlarining ko'pini mana shunday belgilaydilar. Agar siz ehtiyot qismlaringiz uchun qancha muddat kafolat berilishini bilsangiz, ularning kutilayotgan umri haqida juda yaxshi tasavvurga egasiz. Buning hammasi, agar biron bir qism doimiy ravishda ishlamay qolsa, unda ishlab chiqaruvchida nuqson bor yoki uning ishlamay qolishi uchun asosiy sabab bor va siz buni tushunishingiz kerak bo'ladi. Odatda, bu oxirgisi.

Savol: Menda taxminan bir yoshga to'lgan Goodman pechi bor. U bir muncha vaqt issiq havoni puflab ishlaydi va termostatda o'rnatilgan haroratga erishishga harakat qiladi. Bir muncha vaqt o'tgach, maqsadga erishmoqchi bo'ldi. Olovga qarasam, qizil chiroq to'rt marta yonib-o'chib turadi. Filtrni almashtirish va uni oqim yo'nalishi bo'yicha noto'g'ri joylashtirish bu muammoga olib keladimi?

Javob: Yo'q, men filtrni orqaga qarab turganini ko'rmayapman. Men nima ekanligiga amin emasman, lekin o'ylamayman.

Savol: Mening pechim yonib, keyin o'chib qolganda nima bo'ldi?

Javob: Agar u chindan ham tez bo'lsa, ehtimol bu olov sensori.

Savol: Mening pechim odatda o'z-o'zidan ishga tushmaydi. Men pechning yon tomonidagi tugmachani o'chirib yoqishim mumkin, keyin u ishga tushadi va ishlaydi, aks holda u kamdan-kam hollarda boshlanadi. Men termostatni almashtirdim, ammo muammo saqlanib qolmoqda. Induktorli dvigatel ham juda yangi. Chiroq miltillamaydi. Bu nima bo'lishi mumkin?

Javob: Qarorni taklif qilish uchun bu erda etarli ma'lumotga ega bo'lmasam-da, texnologik qarashga ega bo'lmasdan, siz nima qilayotganingizni davom ettiraman. Ehtimol, bu xavfli bo'lishi mumkin va siz ko'proq kutganingiz uchun ko'proq pul sarflashingiz mumkin, bezovtalik haqida gapirmasa ham bo'ladi.

Savol: Gaz pechingizni boshqarish uchun 80 daraja issiqmi?

Javob: Menimcha ha. Buni amalga oshirishi mumkin, ammo buning uchun ozgina mablag 'kerak bo'ladi.

Savol: So'nggi to'rt oy ichida mening pechimdagi ateşleyiciyi uch marta almashtirishga majbur bo'lishimning asosiy sababi nima edi?

Javob: Taxminan sizda noto'g'ri qism yoki noto'g'ri kuchlanish bor deb o'ylayman. Turli xil ateşleyiciler turli xil voltajlarni talab qiladi ... odatda 80 yoki 120V va agar qism to'g'ri bo'lsa, lekin voltaj bo'lmasa, bu sabab bo'lishi mumkin. Aks holda, agar siz ateşleyicinin yonib turgan joyiga tegizsangiz, bu sizning yangi ateşleyicilerinizi ham buzishi mumkin. Terimizdagi yog'lar HSI ning kuyishiga olib kelishi mumkin.

Savol: Men pechimdan 4 ta miltillovchi chiroqni olaman, ya'ni ochiq chegara tugmasi. Bugun soat -40c, shuning uchun u haddan tashqari qizib ketadimi yoki uni ushlab turish qiyin bo'lganligi sababli o'chirib qo'yadimi? Yoki dolzarb muammo bormi?

Javob: Sovutish uchun filtrni yaxshi havo oqimi uchun tekshiring. Iloji bo'lsa, havo oqimi yaxshi bo'lishi uchun ulanganligini yoki tozalanganligini tekshirib ko'ring. Bu narsalar bepul. Agar yo'q bo'lsa, sizda faqat yomon limit tugmachasi bo'lishi mumkin.

Savol: Mening nurim to'qqiz marta miltillaydi va mening kodim bu ateşleyici ekanligini ko'rsatmoqda. Men ateşleyiciyi ikki marta o'zgartirdim va hali ham issiqlik yo'q! Har qanday yordam juda minnatdor bo'ladimi?

Javob: Kechirasiz, ushbu kodlar har bir brendga bir xil emas va men ularning hammasini bilmayman. Kod faqat ateşleme muvaffaqiyatsiz ekanligini anglatadi, lekin ateşleyici yomon emas. (O'rnatish paytida siz ateşleyicinin ateşleme qismiga tegizolmaysiz yoki u yangisini qisqartiradi, ammo agar muammo bo'lsa va uning bir qismiga teginsangiz, mumkin, lekin yonib tursa, u bo'lmasligi kerak Pechning o'zini yoqishiga yo'l qo'ymaslikning juda ko'p sabablari borligini aytdim va shu vaqtgacha nima bo'layotgani haqida ko'proq ma'lumot olishim yoki muammoni aniqlash uchun elektr sinovlarini o'tkazishim kerak edi.

Savol: Mening pechim yonadi va ishlaydi, lekin u o'chirilganda har doim chiroq o'chadi, men buni qanday tuzataman?

Javob: Sizga termojuft kerakdek tuyuladi.

Savol: Mening tashqi pechim tabiiy gazning hidini sezadi, lekin ichkarida hech narsa yo'q. Bu normal holatmi?

Javob: Men bu haqda hech qachon eshitmaganman va u bilan to'qnashmaganman va bu qanday bo'lishini o'ylay olmayman. Agar siz haqiqatan ham shunday qilsangiz, men uni sinovdan o'tkazgan bo'lardim. Siz hech qachon gaz hidini xohlamaysiz.

Savol: Agar fanning cheklangan simiga ulanadigan qora simga ulangan oq puflagichli dvigatel simi puflagich korpusiga tegsa va u ishlay boshlasa, bu nimani anglatadi? Bu motorni qisqartirishi, ya'ni almashtirishni anglatadimi? Shamollatgich boshqa yo'lni yoqmaydi va to'sar to'xtab qolaveradi.

Javob: Bu qisqa, ha kabi ko'rinadi.

Savol: Pechim ishga tushganda nima uchun uchuvchi chiroq o'chadi?

Javob: Bu kuchsiz alanga bo'lishi mumkin, shuning uchun har qanday havo orqaga qaytishi uni o'chirishi mumkin. Ehtimol, bu vaqti-vaqti bilan uchuvchi. Men shunga o'xshash juda ko'p sonli o'rnatishlarni bilmayman. Yomon termojuft bo'lishi mumkin. Ehtimol, yomon issiqlik almashinuvchisi. Men u erda bo'lmasdan va ba'zi testlarni o'tkazmasdan aniq aytolmayman.

Savol: "Yonish havosi induktori quvvat bilan ochilgan bosim kaliti" nimani anglatadi?

Javob: Bu shuni anglatadiki, bosim o'tkazgichi "yopilishi" kerak edi va u "ochiq" bo'lsa, elektr energiyasining keyingi bosqichga o'tishiga yo'l qo'ymaydi, shuning uchun ham kalit yomon, yoki uni tortib olishga imkon beradigan narsa bor "yaqin". Yomon induktor yoki bloklangan mo'ri bo'lishi mumkin, lekin odatda bu kalit. Bu men tekshiradigan birinchi narsa bo'lar edi.

Savol: Mening eski pechim bor, taxminan 4 yil. Yaqinda u qisqa tsiklni boshladi. Men hamma narsani tekshirib chiqdim va hatto filtrni o'zgartirdim, lekin baribir xuddi shu narsani qiladi. Men eshikni echib oldim va u yaxshi ishlaydi, lekin eshikni orqaga qaytarganimda, u yana tsikllarni qisqartiradi. Muammo nima bo'lishi mumkin?

Javob: Bu iflos bo'lishi mumkin va ko'proq havo istaydi, lekin bu shunchaki past harorat bo'lishi mumkin, bu esa qurilmani ushlab turish uchun ko'proq ishlaydi. Meniki qiladi.

Savol: Menda Goodmanning 13 yoshga to'lgan majburiy havo pechi bor. Bosim tugmachasini bir necha yil orqaga qaytarib oldim va shamollatgichni taxminan bir yil oldin almashtirdim. Hozirda issiqlik olishda qiynalayapman. Pech ishlaydi, lekin ba'zida u issiq havoni puflamaydi. Bu sodir bo'lganda, burnerlar yonib-o'chayotganga o'xshaydi. Men allaqachon termostatni almashtirdim, ammo bu ishlamadi. Har qanday fikr bormi?

Javob: Agar burnerlar ishdan chiqayotgan bo'lsa va deyarli darhol mening birinchi fikrim olov sensori bo'ladi, lekin bundan tashqari, men taqdim etilgan ma'lumotlarga asoslanib maslahat berolmayman.

Savol: Nega tashqi fanat mening pechimni yoqmaydi? U tiqilib qoldi.

Javob: Agar sizning muxlisingiz "tiqilib qolsa", unda dvigatel qulflangan bo'lishi mumkin va uni almashtirish kerak bo'ladi.

Savol: Issiqlik almashinuvidan chiqadigan havo qanday haroratda bo'lishi kerak? 113 daraja to'g'ri yoki 120-125 daraja orasida bo'lishi kerakmi?

Javob: Ventilyatorni cheklash tugmasi haroratlar qaysi diapazonda bo'lishi kerakligini aytishi kerak. Unda EX- 130-160 daraja muhri bosilishi mumkin.

Savol: Pech uzoq vaqt issiqlik tsiklida (~ 30 minut) bo'lganida, induktor dvigatelining 1 soniya davomida uzilib qolganini eshitaman va keyin u qayta ishga tushadi va ishlashni davom ettiradi. Induktorning 1 soniyali yopilishi 30 minutlik issiqlik aylanishi davomida 3 yoki 4 marta sodir bo'lishi mumkin. Faqatgina induktorli dvigatel bu 1 soniya davomida o'chadi. Pechni puflagich ishlashda davom etmoqda. IDM Honeywell termostatini almashtirishga yoki ehtimol yumaloq qo'llanmaga muhtojmi? 14 yoshli Tempstar pechkasi.

Javob: Statning bunga hech qanday aloqasi bo'lmaydi. Sizda o'zgaruvchan tezlik induktori bormi? Ehtimol, uning tezligini o'zgartirish kerakmi? Agar shunday bo'lmasa, u butun tsiklni ishga tushirishi kerak, chunki agar u to'xtasa, bosim tugmachasi ochilib, jihozni o'chiradi va agar shunday bo'lsa, siz baxtli bo'lasiz, bu bir soniya yoki sizda issiqlik bo'lmaydi. Shoshilinch holatga kelmasdan oldin tekshirib ko'rishni xohlashingiz mumkin.

Savol: Mening gaz pechim o ga aylanib, bir necha daqiqa ishlaydi va keyin o'chadi. Men sug'urta vositasini almashtirdim, shuningdek dvigatelni ham almashtirdim. Bu yana nima bo'lishi mumkin?

Javob: Pulni tejash uchun yomonligini bilmasam, narsalarni almashtirmas edim. Men bu erdagi ma'lumotlarga asoslanib aytolmayman, lekin tsiklning qaysi nuqtasida to'xtashini aniqlash yordam beradi. Ehtimol, nima qidirayotganingizni bilsangiz, elektronni sinab ko'rish eng yaxshisi bo'ladi. Agar yo'q bo'lsa, siz texnologiyani chaqirib, ularga tashxis qo'yishga ruxsat berishingiz kerak.

Savol: Sovutgichni qabul qilish trubkasi induktor foniy o'chirilgandan keyin issiq havoni puflamoqda, bu normalmi?

Javob: Yo'q. Qabul qilish hech qachon havoni puflamasligi kerak.

Savol: Agar induktor foniy ishlayotgan bo'lsa, lekin u eskirgan bo'lsa, bu bosim tugmachasining to'g'ri ishlamasligiga olib kelishi mumkinmi?

Javob: Bu mumkin, ha. Kommutatorni ishga tushirish uchun vakuum etarli emas edi.

Savol: 1979 yil mening yuqori qavatdagi isitgich shkafidagi Rheem pechim 1/2 ko'k 1/2 sarg'ish uchuvchi olov bilan yaxshi ishlaydi. U joylashgan eshikning ichki qismida teginish juda issiq, shuningdek shkafning ichki qismi qizib ketgan! Isitgichni ishlatishdan qo'rqaman, bu yong'in xavfi bo'lishi mumkinmi? Shkaf ichidagi issiq eshik va issiqlikka nima sabab bo'lishi mumkin? Nimani tekshirish kerak?

Javob: Menimcha, u juda issiq, chunki u tabiiy tortish birligi va cheklangan joyda. Agar iloji bo'lsa, 40 yoshga to'lganini ko'rib, uni almashtirish uchun byudjet ajratishni o'ylab, albatta tutun / CO detektoriga mablag 'sarflayman.

Savol: Men yangi Patriot 80 moy pechimni o'rnatdim. Ishdan bo'shatildi va hamma narsa ishladi! Brülör ishga tushdi, aylanishi uchun yugurdi va o'chdi. Ammo keyin men harakatlanayotgan issiqlik uchun puflagich ishga tushmaganini payqadim. Men nimani tekshirishim kerak?

Javob: Qurilmaning yangi ekanligini hisobga olib, avval bo'sh ulanishni tekshirib ko'rardim. U erdan, siz haqiqatan ham sxemalarni sinab ko'rishingiz va buzilish qaerdaligini ko'rishingiz va keyin nima uchun ekanligini aniqlashingiz kerak. Taqdim etilgan ma'lumotlarga asoslanib ro'yxatlash uchun juda ko'p imkoniyatlar mavjud.

Savol: Salom. Menda ikki yillik RUUD gaz pechkasi bor. To'liq 8 daqiqa ishlaydi, keyin hamma o'chadi va 30 soniyadan keyin qayta boshlanadi. Ushbu tsikl kerakli haroratga yetguncha takrorlanadi. Men termostatni chetlab o'tdim va xuddi shu narsa sodir bo'ladi. Takliflar bormi?

Javob: Ba'zan 2 bosqichli o'choq buni bosqichlar oralig'ida bajaradi, lekin agar bu tsikl davomida doimiy ravishda sodir bo'lsa va siz statdan sakrab chiqsangiz, men avval salom chegarasidan shubhalanaman. Filtrni tekshirib ko'ring, agar siz jihozni tozalamagan bo'lsangiz ... bu juda ko'p havo plenumdan chiqmayapti. Bu shunchaki uzoqdan kelgan taxmin va agar u erda bo'lganimda nima tekshirar edim.

Savol: Mening pechim menga "ateşleyici yoki tuproqni tekshiring" degan xatolarni keltirib chiqarmoqda. Shamollatgich ishga tushguncha hamma narsa to'g'ri ishlaydi. O'sha paytda burnerlar o'chadi va shamollatgich bir daqiqaga yaqin ishlaydi. Keyin u o'chadi va jarayon yana qaytadan boshlanadi. Men murojaat qila oladigan narsa bormi?

Javob: Afsuski, siz tuzatishingiz mumkin bo'lgan oddiy narsa bo'lsa ham, men sinovlarni o'tkazmasdan muammoni aniq aniqlashga yordam berolmayman. To'sarni qayta o'rnatib ko'ring va filtringizni tekshiring. Oddiy ko'rinadigan biron bir narsa sodir bo'ladimi-yo'qmi, qarang, aks holda elektr sinovlari o'tkazilishi kerak. Kechirasiz.

Savol: Nimaga elektr pechi o'chirgichni o'chiradi, lekin a / s emas?

Javob: Ushbu ikkita birlik alohida davrlarda (yoki bo'lishi kerak), shuning uchun bu g'ayritabiiy emas.

Savol: Isitgichdan foydalanganda tashqi HVAC moslamasi ishqibozi ishlashi kerakmi?

Javob: Bu issiqlik pompasi bo'ladi va har doim ham emas. Ventilyator kompressorni sovitadi ... hozirda ko'pchilik uchun muammo emas, agar kerak bo'lmasa u ishlamay qoladi.

Savol: Mening pechim 10 yoshda va bir yilda ikki marta bitta kompaniya tomonidan tozalanadi va tekshiriladi. Bir oy oldin fella chiqdi va uni hech kimda bo'lmaganidek tozaladi. Uning hamma joylari bor edi! Endi filtrlar har ikki haftada iflos ... nima uchun biron bir fikr bor? Qora rang.

Javob: Agar ilgari puflagich chiqarilib tozalanmagan bo'lsa, u yaxshi ishlashi mumkin edi, shuning uchun ko'proq changni yutish mumkin edi.

Savol: Yoqilganda portlash bo'lsa va u o'chirilgan bo'lsa, pechni qanday tuzataman?

Javob: Agar bu kanalni yog 'bilan konservalash bo'lsa (odatda bu tovush turi ... ventilyator bilan bosim va bosimni pasaytirish), siz zaif joyni topishingiz va uni kuchaytirishingiz kerak.

Savol: nima uchun shamollatgich doimo ishlaydi va hech qachon o'chirilmaydi?

Javob: Agar u "doimo" ishlayotgan bo'lsa, u holda sizning ventilyatoringiz tugmachasi "avtomatik" o'rniga "fan" ga o'rnatiladi yoki past kuchlanishli simlar, stat yoki taxtada qisqa bo'ladi. To'xtashini tekshirish uchun siz past kuchlanishni taxtadan uzishingiz mumkin. Muammo taxtada (agar u ishlashni davom ettirsa) yoki simlar va statda bo'lsa, bu sizga xabar beradi. Keyin, u erda simlarni qayta ulang va statni uzing. Agar fan ishlayotgan bo'lsa, unda stat yaxshi, va muammo simda. Yashil sim fanni boshqaradi. Shunday qilib, qizil rang yashil rangga tegsa, fan doimiy ravishda ishlashiga olib keladi. Siz nima qilayotganingizni bilishingizga ishonchingiz komil bo'lsa, buni amalga oshiring.

Savol: Men to'rtta rangli nuqta (oq, sariq, qizil va ko'k) bo'lgan to'rtta chegara kalitlari bilan ta'minlangan yangi tortish induktorini (egzoz puflagichini) o'rnatmoqdaman. Mening pechimda faqat ikkita chegara tugmachasi bor, yuqori chegara tugmasi ko'k, pastki qismi sariq nuqta. Men faqat hozirgi sariq nuqta pastki chegara tugmachasini almashtirganim uchun yangi sariq nuqta cheklash tugmachasidan foydalanishim to'g'rimi?

Javob: Sizga turli xil birliklarda ishlatilishi mumkin bo'lgan "to'plam" kelib tushgandek tuyuladi, shuning uchun ha, buni yaxshi bilishingiz kerak bo'lsa ham, ehtimol men ikkala chegarani ham bajargan bo'lar edim, lekin hech bo'lmaganda sizning qurilmangizga o'tadiganlarni zaxira sifatida saqlang.

Savol: Mening pechim yaxshi ishlamoqda. Uyning old qismidan tashqariga chiqarildi. Nega faqat o'choq yoqilganda tashqarida bunday g'alati hid bor?

Javob: Men bilgan yagona yomon hid (chirigan tuxumga o'xshash) yomon issiqlik almashinuvchisi natijasida bo'lgan. Siz ekanligingizni aniq aytmayapman, chunki nima hidlayotganingizni bilmayman, lekin odatda bu teshiklardan yomon hid bo'lmaydi.

Savol: Termostatdan issiqlik chaqiruvi boshlanganda induktorli dvigatel ishga tushmaydi yoki yarim burilishni amalga oshiradi. Dvigatel qo'lni aylantirganda juda yaxshi aylanmoqda. Mening pechimning induktorli dvigateli buzilganmi yoki bosim o'tkazgichi singari boshqa bir narsa ishlamayaptimi? Chiroq menga 31 kodini beradi.

Javob: Sizning induktoringizda kondensator bo'lishi mumkin, bu yomon. Hamma bo'linmalarda ham mavjud emas, ammo ba'zilarda mavjud. Agar shunday bo'lmasa, ehtimol taxta induktorga kuch yubormaydi. Buning sodir bo'lishiga ishonch hosil qilish uchun siz kuchlanishni tekshirishingiz kerak edi va agar u aylansa ham, vosita hali ham yomon.

Savol: Pech ishlaydi va uyni yaxshi isitadi, lekin uy quruqdir. Pechni namlagich ishlamoqda, ammo uy hali ham quruqmi? Men nimani sinab ko'rishim mumkin?

Javob: Namlagich tomonidan yaratilgan namlik foizini oshirdingizmi? Namlikni qo'shish bu muammoni hal qilishning yagona usuli. Ehtimol, namlagichingiz to'g'ri o'lchamagan bo'lishi mumkin. Yana biron bir narsani qo'shishni istardim, lekin haqiqatan ham hamma narsa ishlayotgan bo'lsa, "tuzatish" yo'q.

Savol: Deyarli har kuni ertalab uyg'onganimizda va uyimiz muzlaydi. Bizning pechimizga borganimda, men 10 va 61 xato kodlarini ko'rmoqdaman. Nega biz doimo shamollatuvchi xatoga duch kelamiz? Pech butunlay yangi!

Javob: Bu sizning muammoingiz ekanligiga amin bo'lmasam-da, ko'pincha kimdir puflagich bilan bog'liq muammolarga duch kelganda, bu o'choqqa keladigan havo etarli emasligi sababli. Bu iflos filtr, o'lchamsiz kanal yoki qaytib keladigan havo registrlari etarli emas. Bu, ayniqsa, eski uy kanallariga yangi moslama o'rnatilganda tez-tez uchraydi va kanal yaxshi qayta tiklanmagan.

Savol: Mening gaz pechim modelim nugm100ehb1 yonish havosini uy ichidan oladi, bu to'g'ri yoki to'g'rimi?

Javob: Ha, bo'sh havo maydoni etarli bo'lsa. O'rnatish bo'yicha qo'llanmada sizga qancha kvadrat metr kerakligini ko'rsatadigan jadval mavjud. Bundan tashqari, bu sizning modelingizga taalluqli ekanligiga amin emasman, ammo ba'zilari bu jihozga kafolatni qisqartiradi deb aytishadi. Buni bilish uchun siz o'zingizning qo'llanma va kafolat tafsilotlarini ko'rib chiqishingiz mumkin.

Savol: Bizning pechimiz faqat havo olish trubkasini pechdagi ulanishdan ajratib olganda ishlaydi. Havo qabul qiladigan trubaning aniq bo'lishini ta'minladik. Pech - bu to'qson foiz samarali pech. Takliflar bormi?

Javob: Havo qabul qilish masofasi juda kichik bo'lishi mumkin. Masofani hisobga olgan holda kerakli o'lchamlarni tavsiya qilish uchun siz o'rnatish qo'llanmasiga murojaat qilishingiz kerak.

Savol: Nega mening pechkali gaz klapanim doimo ochilib turadi?

Javob: Men u nuqsonli va almashtirish kerak yoki noto'g'ri simlarga ulangan va buyruqni ochishdan ko'ra doimiy quvvat olayotganini aytmoqchi edim.

Savol: Mening termostatimning taymeri bor (ketish / qaytish va h.k.), shuning uchun mening pechim birinchi marta so'ralganda haroratga ko'tariladi, ammo keyin keyingi intervalgacha o'chadi. Nima deb o'ylaysiz?

Javob: Bozorda yuzlab termostatlar mavjud, shuning uchun sizga qo'llanmani o'qishdan va dasturiy ta'minotingizni ikki marta tekshirishdan ko'proq narsa ayta olmayman. Ehtimol, biror narsa noto'g'ri dasturlanganga o'xshaydi. Afsuski, ularning barchasi boshqacha dasturlashadi, shuning uchun men taxmin qilishni xohlamayman.

Menda 6 yoshli Goodman propan pechi bor va yaqinda o'choq induktori issiqlik boshlanishidan oldin 4-5 marta havo puflashi kerak edi. Xizmat ko'rsatuvchi kishi chiqib, hamma narsani tozalab tashladi va, albatta, u shu erda bo'lganida juda yaxshi ishladi, ammo keyinchalik u yana yangradi. U uning induktorini o'ylaydi, lekin men puflagichning vazifasi havoni puflash deb o'ylardim. Sizda biron bir fikr bormi?

Merlin M 2019 yil 6-oktabrda:

Salom Dan,

Hayoliy maqola, rahmat.

Bizda eski Heil pechi bor, uni tez orada almashtirish kerak bo'ladi. O'sha paytgacha biz sustlashishga harakat qilmoqdamiz (kichik shahar va pudratchilar juda band)

Our furnace get between step 7 & 8 but the short cycles. After the system warms up (flame burns for ~60 sec) the blower comes on but then the system starts to short cycle. Flame is on for about 2sec then off, one 2sec off and so on. Heat is delivered to the vents but clearly this is not right.

I have done the basic, check filter, change thermostat batteries, looks on roof to ensure eventing. At first I thought flame sensor but tow problems with that,

One, if that was the issue why would the furnace warm up. My thought is a bad sensor would prevent this. And two, for the life of me I cannot see a flame sensor on this unit.

Any suggestions?

Camster on March 13, 2019:

Hi Dan. So yesterday a furnace technician came to inspect my 23 year old Lennox High Efficiency Gas furnace. He said that the temperature in one of the ducts registered 68 degrees and if it reaches 70 the furnace will shut down. He said I probably need a new furnace. What is he talking about please?

[email protected] on March 08, 2019:

Every time we cut our furnace on into the old one it's one of the fan blowers fucking ancient and now it smells and it's smoking so when we cut it off and then we try to cut it back on the next day it just doesn't even turn on what could it be it was really dusty and stuff my life but another filter for it and it's just not working we cut the switches back on through the fuse box and it doesn't cut on and it's getting cold man what do I do what could it be

connie on January 01, 2019:

I have a new York furnace in my garage. I noticed that I feel warm air coming out of the furnace box in garage, while it is dispenseing warm air into the living space.

Dan Rid (muallif) 2018 yil 21-noyabr kuni:

Joe689 - So here's a theory. The old stat was perhaps inaccurate thus maybe the furnace wasn't heating up as much. No perhaps it's running longer thus increasing the temperature in the duct. As it heats up, the duct may expand and as the heat shuts off but the fan is still running and the temperature dropping the duct contracts and causes a "thump" or oil canning sound. I can't really see any other way a thermostat could cause this to start happening other than pure coincidence.

Joe689 on November 19, 2018:

Hi Dan, thank you for the detailed run down. Very easy to follow and intuitive. Thanks for making a complex subject a little easier.

I have a Luxaire gas furnace. I just installed a new thermostat, and started to observe some different behavior. When the thermostat reaches its temp, I hear the "clicks", and then right after the furnace make a thump, deep enough to hear through the floor, and then one more thump almost right after. The fans continues to run for a minute, and turns off. This did not happen with old thermostat. The "thumps" also does not happen all the time. I try to recreate it by toggle the temp up and down but can not get it to repeat. Only when it has been on for some time, does this thump upon signal to turn off occur. And it does not happen all the time. By the way, this is for heat. What could this be? I know it is not the fan because the fan does not turn off right away. It is right might the thermostat clicks.

It never happened with old thermostat. I am about 99% sure I wired it correctly. All my wires were labeled, and I also wrote down what lettered slots they were going in on the former thermostat. With that, it was pretty much 1:1 with the new thermostat.

Thanks in advance

Dan Rid (muallif) on November 15, 2018:

Ray - While I can't be sure what the issue you're having is I can say that typically a unit that runs until there is a failure will automatically kick on the blower as a default safety feature but it should shut off within 5 minutes or so after that. If you're having a limit issue, this could be why you're having problems. Perhaps, since the part is cheap and easy to change, try replacing it and see if that doesn't resolve the issue.

Ray Brewer on November 15, 2018:

I have a furnace that if it stays on for a long period of time will trip the limit switch and blow cold air and the only way to shut it off is switch the breaker off. I have a new filter and all my vents are open. Not sure what else to check?

Dan Rid (muallif) on October 29, 2018:

Ryan - There are a few things that could be going on and it would probably be best to get an HVAC technician out there to look at it. Gas isn't anything to mess with and hopefully not but you could have a heat exchanger issue and that would definitely require a tech to repair. Good news would be that you likely still have a warranty on the exchanger if it is your problem. (Not the labor to install it but the part itself.)

Casey Rohman 2018 yil 28 oktyabrda:

Thank you very much for your reply, Mr. Robbins. My post here didn't appear when I checked back after posting, thus my late response. The breaker is the proper size, and no other electrical problems are appearing in the house.

However, your advice regarding an electrical problem was correct. I think that even though I was careful to reconnect the new control panel properly, it seems likely that at least one of the connections was a bit loose. After I went through and rechecked them all as well as other electrical connections in the furnace, the problem disappeared and the furnace has been functioning properly since. Your patience and willingness to help are much appreciated!

Ryan Jewell on October 26, 2018:

I have aTrane 2 stage furnace. It makes it to around item 7 in your start up list. The furnace will be lit for about 15-20 seconds and then go out... I can hear a waffling whistle noise and see fluttering in the flame at the exit of the gas tubes like it has too much air or not enough gas flowing. And then the middle to further away from ignitor gas lines blow out and it cuts gas to the unit to shut off. Any thoughts on what wrong?

Dan Rid (muallif) on October 26, 2018:

You're welcome Brian. Glad I could help some. Best wishes!

Dan Rid (muallif) on October 26, 2018:

Tom - I'm sorry no. There isn't enough here for me to offer sound advice. Perhaps the limit? Those are a common failure in older furnaces.

Brian S. Pollack on October 25, 2018:

Hi Dan,

Thanks for the input. It is the pressure switch. I can now return the control panel I ordered and had someone else install the pressure switch. Next time i'll know. thanks for your expertise!

Tom on October 25, 2018:

I have a old furnace it’s cal a Stewart Warner . It about 40 years old. I just had the thermal coupling replace and it was working fine then it warm up outside so I turn it off. Then when I needed heat again it wouldn’t come on. I can hear the click in the thermostat To on the furnace but nothing any idea?

Dan Rid (muallif) on October 23, 2018:

Don - This sounds more like a pressure switch problem to me. Perhaps check out my article on that and see if it helps.

Dan Rid (muallif) on October 23, 2018:

Brian - I would be more inclined to think it's the flame sensor or pressure switch. If the sensor is dirty or pressure switch is weak, it could be giving a false failure that can happen within split seconds causing the valve to click open and closed but so fast that the flames don't actually go out. This is my thought from a far. Perhaps check them and see.

Dan Rid (muallif) on October 23, 2018:

Casey - When there are multiple part failures in a row like this I always consider the incoming power and circuit. Is the breaker sized properly? Is the furnace on it's own dedicated breaker? Are there any other "occurrences" in the home with other appliances or lights? I wish I had an easy answer here but testing will definitely be required to definitively pinpoint the issue.

don murray on October 20, 2018:

Hi Dan, I have an older carrier furnace, light is on constantly, and no blinking noticed. Inducer spins, I hear the blower sound, igniter glows hot, then everything shuts down.

I just replaced the gas valve, and now the same thing is happening. Har qanday fikr bormi? could the gas valve I just put in be bad ? The gas is turned on to the furnace, lol...

Brian Pollack on October 20, 2018:

I am trying to figure out what going on with my Trane XE80. It can be either the limit switch, control panel, or gas valve that is clicking. The furnace runs, no problems with the start. It remains on and about ten minutes into blowing hot air it will click about 5-10x. The flames will flicker on and off with each click. The furnace is still running, the flames come back continually and the clicking goes away.

I have already checked the thermistor. Har qanday fikr bormi?

Dan Rid (muallif) on October 18, 2018:

While your message isn't clear to me I can say that changing the filter will help keep temps down but has nothing to do with the pressure switch. The problem may be the pressure switch however the 2 are not related. Perhaps check out this article and see if it helps...https://dengarden.com/appliances/Everything-You-Ne...

Reed Wickstrom on October 17, 2018:

I have a Heil 2 stage filter and it does nothing when thermostat calls for heat; however, if I unplug the limit switch the inducer motor starts and then shuts off around 30 seconds later after I reconnect it. FYI, I checked the furnace filter and it was dirty. I am thinking that it overheated. Do you have any suggestions.

Dan Rid (muallif) on October 11, 2018:

Call the company who installed it and ask them to check it out.

Carol miller on October 11, 2018:

I have a 2 month old heater/air con. Installed and it gets very very hot to touch. What should i do?

Dan Rid (muallif) on May 16, 2018:

Craigh S - I can't be sure without testing. Maybe the board is bad? Are you sure it's the rollout switch and not the temperature sensor on the blower housing?

Craigh S on May 14, 2018:

Why would rollout switch error show when it a/c is used but not when heat is used?

Dan Rid (muallif) on May 01, 2018:

Derek - I really can't think off why these two would be running simultaneously because of your cutting concrete unless you got water on the board and shorted something out. I could maybe understand just the blower but not along with the inducer. And are you sure this is a result of your work or that you just happened to notice because you spent so much time down there?

dgrandstaff on May 01, 2018:

I was cutting concrete close to the furnace and there was a lot of dust, now the exhaust fan and the blower run at the same time nonstop.

Dee Kae 2018 yil 25 martda:

Thank you for responding.

Dan Rid (muallif) 2018 yil 25 martda:

Well Dee, Like other mechanical working things, they sometimes just do something weird and turning off and on the stat can trigger a new call and voila, it works. I wish I could offer a better explanation but it does happen. My furnace will sometimes shutdown on a real cold night because I believe the "heavy" cold air along with a right wind direction overcomes the pressure switch/inducer and can trigger a lock out. Wind stops, I reset the unit, voila...it works. It is very difficult when a cause can't be pinpointed. Next time the furnace shuts down see if you can catch the blinking red light code and maybe that would help.

I have a Tud-B series older Trane furnace. It is cleaned professionally every fall and last fall HVAC said it's still in great condition. On Feb. 22, March 3, March 6 and March 25, the furnace stopped working but started again when the thermostat was turned off and back on. I haven't called HVAC yet because it's happened late at night and on weekends so it has seemed to be better to try turning it off and on first. Once last summer the newer air conditioner stopped and they couldn't duplicate the problem because it started working when they got here and turned the thermostat back on. I have a newer electronic programmable thermostat. I've changed the batteries twice (display was still working), cleaned it (no visible dust) and tightened a loose anchor screw. What else could cause my problem besides a faulty thermostat? Turning the thermostat off and right back on has turned the furnace back on all four times. Rahmat!

Dan Rid (muallif) on March 06, 2018:

I would say perhaps you have a slow close gas valve however if it keeps running or goes into lock out then I don't think that's it. It sounds like the valve itself maybe going bad. It's a "normally closed" valve and if the power is being lost in the valve then it will not hold it open and thus creating this intermittent issue. I can't swear to it without running tests but I would have it checked out because it will cause other components to wear out if it's constantly starting and stopping.

RandysPCs on March 06, 2018:

I have a Coleman furnace that acts like it's running out of gas sometimes. I have watched it and what happens is, the induction fan runs, ignitor glows, gas lights but then gradually the flame gets smaller and goes out. Then the gas valve clicks off and the cycle starts over, sometimes it will stay running sometimes it goes into lock out. Har qanday fikr bormi?

Dan Rid (muallif) on March 06, 2018:

Lowski - I'm nearly positive it's the flame sensor and is probably just a bit in need of a cleaning. You likely won't even be able to see dirt on it but it doesn't take much at all. I've written on how to do this so perhaps if you need some guidance you could check that out. O'qiganingiz uchun tashakkur.

lowski on March 05, 2018:

Hi Dan,

I recently replaced the circuit board on my Ruud 80%. Apparently there was a bad relay, causing my inducer motor to constantly switch between hi and low, delaying the furnace from ever igniting. Since I switched out the board, it has worked fine, with the caveat that every once in awhile, when the inducer motor turns on and the pressure switch makes, I hear the gas ignite but then turn off right away; but the blower motor still comes on and blows cold air. Once the blower motor turns off, the inducer comes immediately on and the whole sequence starts again, but this time with the flame staying lit and working properly. Fikrlarmi?

Dan Rid (muallif) 2018 yil 26 fevralda:

Roger, There are a lot of possibilities based on the info you've provided. I would need more to offer any sound advice. Maybe igniter is bad? Maybe inducer/pressure switch is preventing it due to obstruction or part failure? Maybe board? I'm sorry but I can't help much at this time.

Roger 2018 yil 26 fevralda:

furnace turns on but the igniters don't light up.

Dan Rid (muallif) on January 27, 2018:

I don't think it's either to be honest. Sounds more like an intermittent pressure switch issue. See my reply to John.

Dan Rid (muallif) on January 27, 2018:

Sounds similar to how a pressure switch will act sometimes. It's cheap and easy to fix so maybe give it a try if it's in the budget.

Jakobsdad on January 26, 2018:

My furnace works perfectly for one or two cycles then it goes through the start up process but the igniter doesn't come on. The furnace continues through the whole start up process then blows regular air through the system. if I turn the thermostat to the off position and then back to heat it works perfectly for one or two cycles then repeats. do you think this is a thermostat issue or an igniter issue? the igniter works as it should after the manual power cycle from the thermostat.

Jon on January 26, 2018:

My furnace works perfectly for one or two cycles then when the thermostat calls for heat the igniter doesn't light and it blows cold air only. I can turn the unit off then right back on and it works perfectly again until one or two more cycles then I have to repeat a powering down to get it to work

Kathleen8 on January 26, 2018:

You are probably right! hahahhaha I figure it there was a problem, it would have shown itself by now. Rahmat!

Dan Rid (muallif) on January 25, 2018:

And though I hate to say it, that may be exactly why this is an issue for you. Furnaces aren't as quite when you have to sleep next to one as they are in a basement and is likely why the evenings seem worse...it's quieter, colder, and you're right there for it all.

Kathleen8 on January 25, 2018:

Honestly, I don't know about furnaces. It's a Carrier 59SC5A I believe.. I don't believe the manual says it's 2 stage. I thought the filter was dirty, so I changed it with a nice Filtrete filter and no sluggish noises upon the start of cycling. Then 3 weeks later, it started doing it again. I looked at the filter and it was dirty again. So, I jut put in a filter from ACE Hardware and the noise came back. It will only usually happen in the evening when it actually does happen.. You hear the switch and then it's this sluggish noise like it's having a bit of trouble getting going) from what I assume is the air draft inducer and then it starts blowing just fine. My brother thinks maybe it's just working harder? I can't believe I'm the only person with this issue..then again, I live in a tiny house and the furnace is right there next to my bedroom so I hear EVERYTHING.

Dan Rid (muallif) on January 25, 2018:

Kathleen8 - I can't really say much based on the information here but since it's condensing...is there a chance it's also a 2 stage unit??? If so, the gas output and blower speeds may vary by cycle and whether it's calling for the first or second stage.

Kathleen8 on January 25, 2018:

Hi, I have a Carrier Condensing gas furnace. Sometimes, when the furnace kicks on and starts it's cycle, it sounds sluggish before the blowing begins. Most times, you hear the click, the cycling starts and it starts blowing but it seems like since we are in the midst of winter and it's on all the time, it happens for a few cycles during the evening, but not all the time... Any ideas? Could there be dust stuck somewhere? Rahmat!

Dan Rid (muallif) on January 16, 2018:

Unfortunately there are a too many possibilities for me to say anything certain. Maybe a fan limit? Intermittent pressure switch? Gas valve? Circuit board? Unless you just want to start throwing parts at it, you'd need a tech to troubleshoot the circuit.

Phyrfitr on January 16, 2018:

i have a york 90+ 100,000 btu single stage unit, the thermostat will call , the inducer motor will spin up the solid igniter will glow the gas valve will open and the furnace will cycle, for five minutes or so then the flame will go out but the inducer and blower motor will continue to run, the igniter will glow and the gas valve will start clicking constantly and the flame will ignite multiple times causing multiple fuel ignitions sometimes making a Poof sound, I sit and watch it thru the peep hole, this has been going on now for about A week, Any thoughts ?

Bill Fish on January 14, 2018:

Thanks for responding to my question. You said that my problem might be related to the flame sensor, with the limited info I gave ya. So I cleaned the flame sensor, which was very simple, and my furnace is working great again. I probably saved a couple hundred dollars by doing that myself. Yana bir bor rahmat.

Steve Stark 2018 yil 8-yanvar kuni:

I have a 14 yo Tempstar gas furnace. During a long heating cycle, the inducer motor will cut off for a second and then come back on. This happens maybe 3 or 4 times during the heating cycle. Does the IDM need replacement? Or, could the thermostat be faulty? (round manual Honeywell thermostat) Thanks

Deyl on January 03, 2018:

Have a 10 year old furnace, have it cleaned and checked twice a year. A month ago the fella took the thing apart like never before, put it back together and left. Now the filter is filthy after two weeks. That never happened before. Have any ideas what happened? Rahmat. 1/3/18. [email protected]

Earl on January 03, 2018:

My furnace will not stay running unless the door is off, why?

Dan Rid (muallif) on December 30, 2017:

Angelo - It seems maybe the thermostat is the issue since the furnace will only turn on when the stat says to so perhaps it's not reading properly???

Dan Rid (muallif) on December 30, 2017:

Jeff - I'm sorry but there isn't enough for me to offer much. Check your filter. Could be a high limit switch??? Not sure though.

Angelo 2017 yil 29 dekabrda:

I have Lennox Meritt series that's 13 years old. It started to act weird yesterday. It will only turn the furnace on and maintain the house temperature if the thermostat is set at 73 and above. If I set the thermostat below 73, it will will not turn on the furnace.

Jeff on December 28, 2017:

I have a Coleman I replaced the pressure switch and the thermostat it is running a cycle at two set to 70 but any higher it will run as well then shut off and not fire in less I turn it back down to 70 and cut power and reset it

Dan Rid (muallif) 2017 yil 26 dekabrda:

RK - It sounds like you either need a new motor and/or motor capacitor. I don't recommend using your hand. I suppose it may be getting bad voltage from the board as another possibility but you may want to call a tech.

RK 2017 yil 26 dekabrda:

Hello, I have Carrier weathermaker 8000 gas furnance. Very often furnace would not start and I have to rotate the motor by hand and press the cover switch to start again.. If i leave it, it may start randomly after few hours on its own Any suggestions

Dan Rid (muallif) on December 17, 2017:

Craig, Though I can't say for sure from here, I would first check the hi limit and is the coil for your a/c new too? If not, perhaps it is clogged and blocking air flow??? Is the new furnace fan perhaps more powerful? If so, your ducts may not be big enough on the return side...especially if you added an air cleaner. These are my suspects. O'qiganingiz uchun tashakkur.

Kreyg on December 15, 2017:

Have a Goodman furnace installed on 2016. I set the thermostat to 72 the furnace starts up. Runs for a while tries to make temperature but then cuts off and there is red light blinking 4 times. After a while when the temperature has dropped it kicks back in. I replaced the filter. The thermostat was recently replaced. I have checked the airflow outlet and inlet they don't have any objects. Would a leaking window sill or older windows result in this kind of behavior where the furnace cuts off? This is again a brand new furnace.

Dan Rid (muallif) on December 14, 2017:

Greg, I'm not sure what advice to offer based on this info. You experienced some sort of failure that is apparently intermittent so when you reset the breaker it started over and apparently didn't have the same problem at that time. In short, something is happening to shut down the unit and you'd need to know at what point in the cycle the unit shut down and caused the unit to "lockout". Any failure that happens 3 times will put the furnace into "lockout" for a set period of time before it tries again. Sorry I can't be of much help based on this info.

Greg Staples on December 13, 2017:

Furnace stopped working the other day, wiggled wires, tripped breaker back and forth, after a bit it came on and worked through the night fine. Same thing happened again the next night. Replaced the breaker because there didn't seem to be any power going to the furnace. Furnace is working so far today but when it is running it seems to ossolate power now and then. Har qanday fikr bormi?

Dan Rid (muallif) on December 11, 2017:

Thomas - It sounds like you're not getting enough air flow when the filter is in. Perhaps it's restricting the airflow just enough to make the unit overheat and shut down prior to satisfying the thermostat. Often when adding a high end air cleaner, the ducts coming to it need increased in size to allow for more air to keep the unit temperature within it's confines and not overheat the motor or exchanger. Hope this helps at least to understand what the issue MIGHT be. O'qiganingiz uchun tashakkur.

Thomas on December 10, 2017:

If I remove the air filter on my electric furnace then I heat until it reaches the Nest thermostat selected target temperature. If I place the air filter in, it doesn’t reach the selected temperature but is about 4 degrees colder. What is wrong and what is the fix?

Dan Rid (muallif) on December 08, 2017:

Dave - They can vary. The best way to know your range is to check the High Limit/Fan Switch. There is usually a temp range on there for your unit.

Dave on December 05, 2017:

What should the heated air coming out of heat exchange Be is there a minimum temp ??? Like 120 deg ?

Dan Rid (muallif) on November 12, 2017:

John - That's an odd one but likely an issue with communication between the stat and furnace. I'm sorry but can't offer much there other than rechecking your programming and running electrical tests to see what's making the unit shut down in that first cycle.

John Beattie 2017 yil 11-noyabr kuni:

My gas furnace comes on for the 1st program cycle of the morning but doesn't complete the cycle and will stop with out reaching the programed setting. If I turn the furnace on/off it then acts like it completes a heat cycle without the burners on. Then in a minute or so later the furnace comes on and then regularly runs the rest of the day. what might be wrong?

Dan Rid (muallif) on November 10, 2017:

Ozzie - A high efficient furnace has an intake and exhaust pipe and connection usually. Sometimes guys will let the unit pull air from in the home on the intake and not run it all the way outside. In order to do that, they are supposed to make sure there is enough free square footage to provide the needed intake. Taking that door off may be giving you just enough to do the job but you shouldn't have to leave any covers off your unit to make it run. Hope that helps.

OzzieSch on November 10, 2017:

What exactly brings in the outside air for an efficient furnace? I don't get enough outside air to combust the gas. When I take off a little side cover on the furnace to let in inside air, the furnace works properly. Mening muammom nima?

Dan Rid (muallif) on November 08, 2017:

Lee - If that's the case then they may need a good cleaning. I'm a little stunned though since a flame sensor should detect that the burners aren't lit since one needs to fire to fire the next and the next. ???

Dan Rid (muallif) on November 06, 2017:

Marco - I'm sorry but for me to help I would have to perform electrical circuit testing to pinpoint your problem here. I would start with the thermostat. Sounds like it may be suspect.

Dan Rid (muallif) on November 02, 2017:

Thank you Jonas!

Jonas Porter on November 01, 2017:

This was just an awesome explanation. Rahmat. Rahmat.

Dan Rid (muallif) on October 21, 2017:

Kevin - There is obviously a short somewhere. Likely culprits are the transformer and/or entire board. There could be other causes but this is what I'd suspect. O'qiganingiz uchun tashakkur.

Ok i checked the fuse, i clean the heating sensor and the blower is working, glow ignitor comes on, slow flashing green light. I checked the thermostat ....the problem is i cant seem to get a flame ignited i dint know what else to do...i want to call for help to be my last resort.

Jw clink 2017 yil 19 oktyabrda:

I replaced my ignition last year and furnace work fine.

This year it will not even get hot.

I have a Trane Furnace that I determined has a blown fuse on the control panel. When I replace the fuse and push the black switch that the metal panel touches it instantly blows again.

Aaron on October 13, 2017:

I have a Colman Evcon. It is flashing 4 flashes meaning bad limit switch. Tested all switches and checked out. Have a green flash when unit not heating. Bad board?

Dan Rid (muallif) on October 07, 2017:

Duane - It sounds like it. If the inducer fan/motor is shot then nothing will work as it's the first step in the heating cycle and if it is bad, the whole assembly is usually sold as a piece and is typically specific to it's brand so universal parts aren't likely going to be an option for repair. You'll need to find the distributor for your brand of furnace to find the part most likely. O'qiganingiz uchun tashakkur.

Duane on October 06, 2017:

The induction fan does not start it just hums. It does not spin. Is the fan bad or is there something else I should look for?

Dan Rid (muallif) on September 11, 2017:

Amacblue - The coil sits on top of the furnace. It's not part of the furnace. It is not always possible for a homeowner to do this since sometimes there is not way to access the underneath of the coil where dirt and such collects in which case it would need to be removed and that DEFINITELY requires a service technician. If you can however access the underside, congrats and it should be cleaned but carefully and not to bend the fins over so that air can't pass through. O'qiganingiz uchun tashakkur.

I would like to clean my coil on my furnace however o can't seem to locate it. It is a carrier just like the one pictured thank you

Dan Rid (muallif) on July 05, 2017:

Luis - You may have a blown fuse on the board. It's usually 3 amp fuse that is like that in a car. Can't say for sure but that's where I would start. Thank you for reading.

Dan Rid (muallif) 2017 yil 26 martda:

Robby =- There is a laundry list of things to check from here however it doesn't seem coincidental that this is happening after the stat was changed. Sounds like perhaps your white wire isn't making good contact or in the right spot. Double check your stat wiring. Beyond that, there are too many things to check to list here. Fuse on board? Gas valve? Ignitor bad? Limt? Pressure Switch? I'm sorry I can't be more helpful from here. O'qiganingiz uchun tashakkur.

robby on March 25, 2017:

My heater stopped working yesterday nigh (it had stopped once few months ago, we changed the thermostat battery and it worked fine). After it stopped working, I put a new thermostat and still no luck. These are the few observations, please help in letting me know what is wrong

1) the AC works fine with both thermostat. The AC turns on (outside the house) and the blower blows air

2)On heat, the fan ON position gets the blower working (and you can hear the blower unit below the furnace making noise).

2)On heat, auto, nothing is working. The blower does not work, the flame is not lit (however the pilot flame is lit fine)

While changing to new thermostat, twice on Heat/AUTO, the blower came on but it kept pushing cold air for minutes. Now even that is not happening. Manually pushing the switch in the furnace gets the blower going, but there is no furnace flame(only pilot flame).

Please let me know what to do next

Dan Rid (muallif) on March 08, 2017:

Arash - It sounds like you had/have a short circuit somewhere. If you don't have a voltmeter you will have a very hard time finding it. You may want to call a tech or you could find yourself spending a lot of money on parts you don't need or buying a part that will short again because you didn't identify the source. Thank you for reading.

Arash on March 07, 2017:

Hi Daniel, I have a Lennox hvac with two zone. My heater stopped working last month an no power on thermostats. I notice the fuse on zone controller board is blown. I changed the fuse with a 5 amp. The power return to thermostats but heater didn't turned on again. I ordere a new zone controller but again the fuse blown in new board. So I thought the problem is from main controller board. I ordered and replaced the main controller plus adaptor. Still heater doesn't work. The egniter glows but the gas valve doesn't release gas to flame. I checked the voltage on gas valve and it's not 24v. It keeps trying ignite and doesn't go to watch guard mode. Would you please help me to figure it up? rahmat

Ccole456 on February 21, 2017:

Rahmat. I looks up the difference and it appears it is an ignition board. Thanks for confirming. We have a number of things to try and hoping to keep the unit going for at least a few more months!

Dan Rid (muallif) on February 21, 2017:

If you have a spark ignition board then you perhaps will not have what I was thinking of. My apologies. There are so many boards out there and this was not what I was envisioning. It would be in plain site if you could change it and I don't believe you can open those without causing further damage.

Ccole456 on February 21, 2017:

Daniel- Curious if you can assist in locating the fuse on the board. The white Rogers control seems to be sealed. The fuse would be inside the case correct? The main fuse at the switch is fine we did check that one.

Dan Rid (muallif) on February 21, 2017:

Perhaps you've blown the fuse on the board. Typically a 3 or 5 amp automotive type fuse and/or perhaps the 120v/24v transformer took a hit. That could be the humming you hear. All of these are cheap places to start. I'm sorry but troubleshooting over the net is very tough so I try to recommend some of the simplest, cheap repairs to folks.

Ccole456 on February 20, 2017:

Daniel Robbins thanks. Nothing we have read or viewed yet has led us to the capacitor. Haven't been able to make any of the initial trouble shooting techniques give us a clear yes or no. We had a number of power failures from wind the day before it stopped working. If I understand you the the old White Rodgers control panel should illuminate to indicate at least something.

We will look into the capacitor then probably need to call technician if that doesn't work?

Dan Rid (muallif) on February 20, 2017:

Ccole456 - Sounds like the main blower isn't turning and that humming may be the motor trying to start. There is a capacitor usually mounted to the blower housing that may be bad and would be a cheap easy place to start and if that doesn't work, perhaps the blower is shot. That said, if the light on the board isn't lit, then you may have taken a hit electrically and then the potential possibilities get to be too many to cover here. That said, I would start at that capacitor. O'qiganingiz uchun tashakkur.

Ccole456 2017 yil 19 fevralda:

York gas furnace clicks on and then you hear a low continuous buzzing noise (seems to come from near the control panel) and nothing else happens. Replaced inducer motor thinking that was the problem, same issues.

Stat working and fan doesn't turn on when switched "on" at stat. Getting power where stat wires connect to pressure switch. Tubing at pressure switch appears unblocked and in good shape.

Could it be the pressure switch? Could it be the control panel? There is one light on control panel but it doesn't illuminate, no blink code, nothing. Could it be something else? Fikrlarmi?

Jill on February 08, 2017:

Just replaced an oversized furnace with the right sized one as i was having issues with the furnance constantly coming on. I lowered the thermostat several degrees during the day so it would not come on as much. With the new furnace I thought this would all be resolved but it has not. It comes on more frequently and even with the temp set lower it comes on every 10 mins. Any advice? I've been dealing with this for 2 years and I just want an answer!

Wayne Hogan on January 31, 2017:

Have a 2-stage furnace. furnace runs great on high, runs for about 2 minutes on low then gas shuts the gas valve and the cycle repeats many times till thermostat is met. I have replaced the roll out switch and flame rod and it still occurs. Any suggestions?

Chris taft 2017 yil 22-yanvar kuni:

Carrier weathermaker has been having flame out problems, had a tech come out and tell me that the intake/exhaust wad too small and needed to be 3", so all that is changed and now it seems like it won't cycle back to back without having an issue. Turn power off to furnace and back on will work for 1 maybe 2 times. Any advice?

Dan Rid (muallif) 2017 yil 22-yanvar kuni:

Michael Riemer - Not real sure. Could be too large of BTU. Could be the LP kit to make it LP wasn't adjusted properly. Could be a new stat is more accurate and the old one wasn't keeping the temp as consistent. Sorry but this is a tough one that would require further investigation onsite than I can provide here.
