To replace a bad relay, what should I have to replace together? My LG Model No. is LSC27931ST.
The part numbers that you will want to replace if the relay is bad is the relay [EBG42993602] and the overload EAF39584205.
My Display on left door will not come on, fridge & freezer both work , lights works just no controls to turn up temp or down. called LG said maybe a relay on mother board?
The first thing that you will want to check is to make sure that the wire harness at the top of the door does not have a broken or loose connection. If this checks ok then the most likely cause of the unit not having a display would be the dispenser board, but you will want to test for power to the board to make sure.
