Here goes....as of a little over a year ago, the system quit automatically coming on about 90% of the time. We were having to turn on the fan to let it run for a few minutes, then the heat would start working...then we could switch back to auto and everything was good until the next time it wouldn't come on again. Now, the heat is not coming on at all! Any obvious suggestions? I am by no means an electrician or HVAC person!

HELP!

Hi,

No guarantees, but most likely a bad sequencer.

Sequencer # 3115 - 3571 can be seen and ordered here by paging down:
