Customer Questions and Answers for Refrigerator Main Control Board by Ge

P.R. Smith, If it is just the freezer compartment that is not cooling then you will want to pull the rear panel and see what the evaporator coils look like. If the coils have a full even frost pattern then you will want to make sure that the evaporator fan motor is running. If the coil is impacted with ice then the control board would most likely be the issue. If there is very little frost on just the top part of the evaporator then it would be caused by a restrictions or possible leak in the sealed system.
