I could not figure out why the high wire doesn’t operate. There is no speed selector switch to test. The wires are plugged into the control board.
Unfortunately I think I blew the electronic compressor circuit on the expensive Bluetooth thermostat because when I hooked it back up the compressor would not stay on. I re-installed the original thermostat and it’s working. I didn’t hook up the hi fan since it sparks on application of power.
So it could be the wire or the control board I guess.
The impeller turns freely as does the fan blade but I noticed the impeller has a chip in it wher part of a fin is broken off. That seems weird.
