I've never heard of it or ran into it and cannot think of how that would be. That said, if you really do, then I would have it tested. You never want to smell gas.
My cold air intake pipe is blowing hot air after the inducer fan shut is off, is that normal?
My 1979 Rheem furnace in my upstairs heater closet works well with 1/2 blue 1/2 yellowish pilot flame. Inside the door where it's housed is very hot to the touch and also the inside of the closet is heated up! I'm afraid to use my heater, could it be a fire hazard? What could cause the hot door and heat inside the closet? What should be checked?
When the doors of the furnace are on, the furnace 'buzzes' very loudly like a large bee stuck inside. If I take the doors off, or only partly put them in place, it is quiet. Is it having difficulty drawing air?
My furnace is working fine. It is vented out the front of the house. Why does it have such a strange odor outside only when the furnace turns on?
Does the outside HVAC unit fan need to be running when using the heater?
I'm getting 4 flashing lights from my furnace, meaning an open limit switch. It is -40c today so I'm wondering is it overheating and turning off just because it's having a hard time keeping up? Or is there an actual issue?
