it's a rheem heat pump, copeland scroll compressor
had an issue two weeks ago, seemed to be worn contactor, replaced it, things seemed ok for a couple of days
next replaced thermostat, old mercury switch type for digital, again seemed to have helped but compressor just worked inconsistantly
tonight it just will not stay on, it's almost midnight and it's hot
checked stuff with voltmeter as some other threads suggested, but can't
make sense of it
what readings should be where?
any help appreciated
