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 getting cold.
What could be my problem? Signed, "getting cold in Oklahoma"
Is it plugged in?
That's easy. Your furnace is not working. Let me know if you need any more help.

Easy , burn the furniture, and stop trolling.
He is lucky to even have electricity. We have been without power since Monday morning.
Everyone knows you need to replace the thermost at least 4 times before you get one that works right. Bubba
Bingo. Oklahoma - ice storm - no power -
I told my wife that 400K something people in the heartland were without power. She laughed and said to me "no thats 400K something people without a generator " .
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 ignition 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.
The latest count is 564,000 households without commercial power. There are quite a few with generators including me. :) We have been without power since early Monday morning. They are saying it will be 7 to 10 days before everyone is back up.

You know, on alt.hvac, I sometimes feel sorry for you because the guys pick on you so much, but you claim to be at least a furnace tech, and people like me, a landlord with limited skills, no training, and little experience can figure come up with a plan to troubleshoot this, such as:
1) Confirm the breaker is on and you have 115v at the switch (disconnect). 2) Make sure the switch is on. 3) Make sure the lower door is on to hold the door switch down and make sure that switch is passing 115v through 4) Check for 24v at the transformer secondary. 5) Check the fuse on the circuit boardGeez

Liar you have no friends--oh and quit killing my grandkids kittens you f****ng asshole.
Where should she send your fee?
Electricity? Electricity? Why would a gas furnace need electricity?
Thanks, Mikey. I thought it was time for my annual troll.
Latest news I've seen, more like 800,000 "customers" without generators. And, as much as an inch of ice all over everything. I did an ice storm in
2003, but no where near as bad as this. I lost power for four days, which was plenty enough to make me appreciate generators, heat, etc.I suspect 7 to 10 days is optomistic. Ice storm 1991 in NYS was about 14 days plus for some folks.
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.
Because mine does?
Do you think he is going blind too? ;-p
Could be that the several semi loads of FEMA generators that passed me earlier this evening heading north towards OK haven't arrived yet...
Yeah along with deaf and dumber.
