side by side compressor stops working unplug 4 a while plug back in starts working than stops

Hi guys,

I have a pss26ngpa side by side and notice that it wasn't cooling. Notice the compressor wasn't running so un plugged it and give the grill a cleaning. plugged it back in and it didn't work so I unplugged it and played around with the wires and around part 729 and 733( no idea how to get the cover off). plugged it back in and the compressor started to work. The frig ran for a day or too than it stopped again. Did the same thing and it is working but definitely there is something wrong. Any ideas?

thanks,
-John
