Coldest weekend of the year and our heater goes! Wondering if anyone has ideas about this; 9 year old Rheem, ignitor working, fan working, gas coming into house - burner is not firing up... any thoughts?? thanks!
You should post the model number and attach pictures here of it with the doors open or off -- are there any codes showing blinking? The more info you can give will help with someone knowledgeable replying.
What kind of air filter on the furnace do you use and when was it last replaced? They may want to know this.
