Well I got the new relay with no change. The universal replacement had multiple leads so I tried hooking it up according to wiring diagrams with no change so tried swapping them around, no change then either.
So I am fairly confident its not the relay but I'm not sure what else it could be except from what I read the control board or the compressor. Would be surprised if it was either because they were both performing great until the compressor shut off right in the middle of working fine.
Fan works great when I turn it on. When I set the thermostat to just COOL and ON the fan runs then as well but the compressor doesn't start. If I put it on AUTO the fan nor the compressor starts.
I think its significant when on AUTO not even the fan turns on or seems to attempt to run the compressor. It makes me think something that would give those commands is not working properly. I suppose it could be the control board despite it looking pristine, which I had some way to test it and what results I should be looking for.
I really wish there was some temporary bypass I could try to just tell the compressor to turn on regardless of other signals to see if it will even run.
