Frig stopped working after power surge to house. Replaced relay and overload on compressor, and frig worked fine for three days after plugging it back in. Then, same problem all over again, compressor would not come on and no cooling or freezing. Unplugged frig for a few hours, and when plugged it back in it worked fine. After about seven days frig stopped again. Again, unplugged it for a few hours and it worked fine after plugging it back in. Any suggestions as to what might be causing this problem.

Thank for the response. Don't have the old relay. Only slight noise when you shook it. Parts store rep said probably bad as a result of power surge. Fans, lights and water dispensor all work. Just compressor that seems to be stopping, which will also restart after unplugging frig for few hours. I do have a volt meter and no problems with using.
Again, thanks.

I took the main board off today to check it, and on the back side there was a clear sign of a burn spot. About a half inch in diameter brown spot. Also, a little brown residue on the back of the frig, where it flared up. I agree with you, that the main board has to be replaced. I've also removed the defrost heater to check it for continuity, and to see if its working.
Thanks, again.
