Good Morning Glenn,
I looked in the control panel and took the fan cover off to look for burned or disconnected wires and there were none. I do not have an ohmmeter but am trying to get one today.
When I went to the unit this morning, the fan was running, very low speed though. The thermostat was off, I even turned the unitís control panel breaker off, and it was still running. Do not know if that is significant but wanted to mention it. I went back inside to see if the unit would come one. It was 64 in the house; I set the tístat to 65 and turned the heat on. The light on the tístat blinked for a minute or two but nothing ever happened. Adjusted the tístat to 68 to see if the second stage would kick in and it did. The blower came on and started blowing air. However, compressor did not kick on and fan was still running at very low speed. I did the same thing with the cool. I turned it down to 62; the blower came on and started blowing air but fan still running at very slow speed. (System blowing out stale air at this point) In both instances; the system tripped the outside breaker again within 5 or 6 minutes; the fan cut off and has stayed off now.
By the way, I have taken a picture of the control panel and have posted a large version to a website. Don't know if it will help but CLICK HERE
