Ok, I guess I am at worse than square 1. The heat ran fine the last few times I needed it. Switched to AC not a problem for two months then major (Pump, Blower Fan and circuit board) repairs. AC good again. Didn’t even think about the heat until my mother told me this morning she tried to use it last night and it wouldn’t come on. When it got warm today I checked it out. AC runs like a charm. Set the heat up to 80 and turn it on, it’s like it never gets a signal. Nothing at all changes even the very minor electric hum I hear. I was too busy to do the AC work myself so I had someone do it. I got a call into him but any ideas you guys might have would be greatly appreciated.
