Serviceman here on 10/21/2015 took out the igniter, had to order another one.
Came back on 10/23/2015 put in new igniter. still nothing. said I needed new
brain board. so put one in and said it was good to go. he did not turn on the
unit before he left to see if it was working properly. On 10/25/2015 at
approximately 4:30 a.m. central time I turned on the furnace to rid house of the
chilly air and it ran and ran but no heat. he did not check the thermostat that
may be an issue I don't know I am no electrician. HELP
Tell him to get his butt back there and fix it.
Hope you did not pay.
The guy is an idiot for not testing it but you should also have insisted
that he demonstrates it to you as working.
Hope you did not pay the bill yet.
Sounds like someone who swaps parts wildly in the hope he'll find the
one that's bad.
The most common failures are the igniter, the thermocouple and the gas
valve. Unlikely to be the thermostat or the control board.
The thing is, you can test all of these. You can try lighting the
furnace manually to see if the igniter is bad. You can try opening the
gas valve by applying 24VAC to the terminals to see if it's working
(with the gas off) and if it does open then the thermocouple is suspect.
You can see if the controller board is opening the gas valve or
detecting some other fault.
This is a silly question and not meant to be insulting. People just do
silly things sometimes. Is it set on fan rather than heat? It seems odd
the fan is working before the heat comes on.
Part of my job is trouble shooting. Testing the repair is as much a
the job as replacing things. There are times when we can't test things
always bugs me. I leave with a nagging feeling that I will have to come
at a most inconvenient time.

If over temp. limiter triggers furnace will shut off(lock out mode)
fan will run until furnace cools down.
(this is lock out period) Unless it is very old furnace, it ought to
have diagnostic LED on the board.
Easy to help. Get the guy back and have him fix it. Do NOT pay another
penny either. He should have fired it up before he left. Once he gets
it going, post his phone number some place so you can be sure NEVER to
call him again.
That's for sure. It looks like you have some real idiots working on your
furnace. If you have not paid them, call another REPUTIBLE company.
Report these idiots to the Better Business Bureau too. Anyone with even
half a brain, will test a furnace of anything they are repairing.
However, if the fan is running and it's not heating, make sure the
thermostat is not on the COOLING mode, or FAN ON CONTINUOUS mode.
There could be a bad switch on that thermostat too. You could just
remove the thermostat and (assuming there are only 2 wires), just clip
or twist the wires together and see if the furnace works. If it does,
your thermostat is defective. If it still dont work, it's not likely the
Call the president of the company and tell hir you want it fixed and
you want the bill for the part you didn't need cancelled or refunded.
Be firm but not angry. Read him your post. And get back to us to
say what happened.
