I have one of these Fridges that other than the lights doesn't work at all. The front display has some random LED's lite up which I understand are errors, shouldn't it still run with errors the system picks up? The mainboard has 115V AC going to it but the LED on the board is OFF. Shouldn't it be ON if things are good or Blinking if there is an error. I can't seem to find the service manual for this unit. Any help would be greatly appreciated.
