A/C but No Heat - TempStar - Ignitor Problem?
At the end of last winter my central heat quit working.
The A/C worked just fine all summer. Just no heat.
It's starting to get cool weather so I need to fix this.
I pulled the panel off to inspect it. (power disconnected)
I cleaned all the cobwebs and other junk out of it.
I didn't see anything obviously wrong.
Turned the power back on and got my multimeter.
The unit gets 120vac on both lines coming in.
I unplugged the ignitor circuit from the control valve.
The ignitor circuit has continuity and the control valve
puts out 27volts to the ignitor circuit. (is that correct?)
That was all I could test. I put everything back like it was.
I don't want to just throw parts at it til it works.
So I am hoping y'all have some good advice for me.
TempStar PGF030K080/GPFM20K080 Installed in mid 2003.
Thanks for any help you can provide.
