Pull the refrig out and remove the 8 " x 10 " panel . Behind this panel , is the main control board . Unplug the refrig . Remove the BLUE plug from the board , with 3 larger wires going to it . Looking at the blue plug , the sequence will be wire1,wire2,space,wire3 . Get a short piece of insulated wire , and strip about 1/4 inch from each end . Insert 1 end into wire1 , and the other into wire3 . Plug the refrig back in and see if the compressor now runs . If it does , replace the board . If not , compressor is bad . When testing , ONLY the compressor will run and nothing else will .
When the board is removed , look on the soldered side for a " bulls eye " , a spot behind the black relays where solder has melted away from the pin . If you see this , then resolder the pin , reinstall the board and if the compressor runs , you won't have to buy another board . Save a lot of money . If you don't see a bulls eye , replace the board .
Mike, I did the test and the compressor started running. It didnt before. I pulled the main board and one of the pins on the main relay is burnt, no solder. Wife was saying it was running hard before it quit. Before I replace the board or resolder the pin, what would cause that to happen?
factory board will do that . i would resolder the " bullseye " and continue using that board . The melted solder is on the compressor relay pin , which gets hot and melts the solder , so just resolder .
