A friend of mine writes this:
I live in a two story raised ranch. I have a Carrier furnae in the cellar,
it's natural gas. I have the thermostat all the way to the hottest, and I
even tried another thermostat. The furnace does nothing. Doesn't hum, and
the gas valve doesn't click. The inducer doesn't come on. The house is
What could be my problem? Signed, "getting cold in Oklahoma"
All joking aside -
You need electricity and gas--
Then you need a flame ignition - pilot light or electronic spark.
Then if the thermostat call for heat, the main burner kicks on with flame
With the main burner on, the heat exchanger heats up to a pre-set amount,
and finally a relay kicks in and eclectic power is applied to the fan motor.
Several things can go wrong, mostly around the safety feature(s) that the
main gas valve has to prevent it from opening with no main burner ignition.
Trust me; safety features you don't want to bypass.
Your post focused on thermostat, which is (are) mostly reliable these days.
No information on your fault isolation on electric power, or pilot light
(electronic spark?) ignition.
The worst fault to find in your case might be a broken thermostat wire
between the furnace and the thermostat. Any remodeling last summer? This
is a very remote chance. I think it is pilot light, or electricity.
Yeah, yah. Is that your best shot? Why don't you be creative, and mention my
testicles or something? Oh, no, I guess that's old, too. I guess you could
mention my religion, no, well, that's been done.
Maybe you better stick to kitten insults. They are relatively easy. Anyhow,
you're welcome to flame me again.
