Heating Won't Come on
I have a strange problem with my heater.
It's gas and has automatic ignition.
The temperature is dropping in the house and the heat won't come on. I can hear the sound of what I guess is the furnace humming, but the blower won't start.
The furnace is some contractor brand that came with the house from Goodman Manufacturing. About 10 years old or a little more.
But if I switch the setting in the thermostat to "Fan On" (instead of "Auto") the fan DOES start. It seems like somehow the heater does not communicate with the fan, but the fan does work.
By the way, I thought I smelled gas earlier, but I don't now.
