The ac was running fine and cooling before the power outage. And the power outage was relatively short in duration. not more than an hour max.

Hello, it is quite likely that an electrical spike generated by the power outage damaged your units printed circuit board and that it will need to be replaced.

There are also some other possibilities.

Tell me a lot about your technical skill sets and if you have a multimeter or not please so that I can coach you most effectively.

If none of that is in your skills range, tell me which direction you are from the center of the nearest city and I will get you a short list of the best rated outfits in your area.

We can go from there.

thanks, ***** ***** case take a photo of the wiring diagram glued to the inside of the blower service door, and I will mark it up with trouble shooting instructions. include a photo of the printed circuit card that shows the thermostat wire connections.

(the analog meter does not give false ghost reads, not a bad meter to use here)

Use the paper clip icon at the right end of the tool bar, or the attach files link to the left of your send button to get the pictures to me. Diagram photo must be taken up close, in very good light, from straight on, and exceedingly well focused.

We can go from there.
