Everything seems to be working fine, but then when the thermostat trips off, and the furnace blower fan turns off as it should, the compressor outside keeps running. If I take the cover off the electrical section and give it a sharp rap, it lets go and turns off. So it appears it has to be a relay that's not letting go.
Well, all I can see in there is the main contactor, which has pretty pitted contacts, and the hard-start relay. I was planning on replacing the contactor, but wondered if it could possibly be the start relay that's not letting go.
Thanks
