Compressor overload switch broke in my hand when I removed it but replacing it and the start relay did not fix the problem. I troubleshot the control board with the help of videos from Grace Appliance (https://www.youtube.com/c/GraceAppliance/videos) and found fans were not getting power. I ordered an aftermarket control board that offered free returns but it kept cycling off and on every minute. I think it might have been overloaded because the main resistor in the evaporator fan drive circuit ran very hot. I ordered the OEM control board and the refrigerator is working fine now.
