I just bought a refrigerator and when I plug it in, the temperature control is off. I don't have any power on it but everything else has it. What can be the problem? Thank you
Answer Hello Manuel,
I would first verify that the harness is connected at the door hinge. If so, you will need to go to the main control board WR49X10152 and verify voltage out at the J4 terminal from pin 2 to pin 1 or 3. This will be a low dc voltage, usually from 12 to 18 Vdc. If it is there, you can go to the display board and check for the same dc voltage to the board. If it is not there, a harness issue exists. If it is there, the display board WR55X10418 has failed.
