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"
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 " .
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.
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.

Well, I'm in Oklahoma and fortunately I didn't lose power. But as to how
long it will take. The last 2 ice storms (Christmas 2000 and January 2007)
at McAlester here in Oklahoma my brother-in-laws house was without power
for 11 days. But it depends on a lot of factors. Out in the country
there were people without power for up to a month. Some places they
couldn't get trucks in and had to carry everything in.
After the Dec/Jan blizzard/ice in '05 across W KS/E CO, there were areas
which were well over 30 days owing to such severe conditions and so
much. Sunflower, the distribution arm of the W KS electric co-ops, lost
over 20,000 poles alone. There were a dozen or so of the large HV
cross-country transmission towers down in one area; a section of line
just NW of us was taken down for a complete run of 27 miles with not a
single pole left standing...
While bad, it can be even worse...this time, we were on the SW corner
and stayed just above freezing for the most part. Did get the first 1"
moisture since July 4 weekend so we're pretty happy, actually... :)
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.
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,
1) Confirm the breaker is on and you have 115v at the switch
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 board

Yeah, yah. Is that your best shot? Why don't you be creative, and mention my

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.
