ge fridge no cooling at all no lights on temp control

my ge fridge quit working on both sides. fridge and freezer nothing runs, and the digital temp control does not light up. ice maker and water work, all lights work, just no cooling no temp diplay. the board inside the temp display has been replaced and did not make a difference. wondering if anyone had any other ideas thanks:eek:

Most likely the problem is a bad main control board (#801 on the [B]AP4297272
