After some recent bad weather where electrical power had come off and on in my home, my refrigerator and freezer had stopped cooling. I first tried swapping out both relay switches to the compressor. This was not the problem. I then swapped out the mother board thinking perhaps my recent on/off with my electrical power caused damage to the mother board. This was indeed the solution to the problem. The only difficult part of the job was getting the old mother board released from the plastic tabs. Carefully squeezing the tabs with needle nose pliers and pulling the board off gently got the job done. I must say I am highly impressed with the videos on how to repair. I usually have the Midas touch in reverse when it comes to home repair, but Appliance Parts Pros saved me a $2000 expense for a new refrigerator. Thanks !
