Customer Questions and Answers for Refrigerator Main Control Board by Ge

Chris, If the fans and compressor are working, then the issue would be a restriction or a loss of refrigerant in the sealed system of the refrigerator. You'll need to remove the evaporator cover (freezer back wall) and check for a smooth even frost pattern on all the evaporator coils. A partial pattern would indicate a restriction, and no frost pattern would indicate a loss of refrigerant.
