Freezer and refrigerator not getting cold. Unplugged for a couple of days and plugged back in. Both sides worked for a few hours and stopped working again; compressor not running. Replaced starter relay and overload protector; unit worked for a few hours and stopped working again. Compressor cooling fan is running, so are the evaporator fans but the compressor is not running again. Checked compressor terminals with meter; readings were 6.0 - 6.2; 2.0 - 2.2 and 7.9 - 8.0. Don't know what to do again. How do I know as to which is the culprit: compressor or control board? HELP!!!!!!!
