Display shows CC2 and the freezer compartment is too warm.

Safety first: Unplug the refrigerator before removing panels or working near moving parts.

• Check door seal: Inspect the freezer gasket for tears, gaps, or debris. Close the door on a sheet of paper; if it pulls out easily, the gasket may not be sealing and should be replaced or adjusted.
• Look for frost patterns: Remove the rear freezer panel. A solid block of ice on the evaporator indicates defrost failure; a small frost patch only in one corner suggests a sealed system problem.
• Manual defrost if heavily iced: Unplug and defrost completely for 24 hours to restore airflow temporarily, then diagnose defrost components (heater, thermostat, thermistor, control board).
• Thermistor testing: Test the freezer thermistor with a multimeter. Replace if resistance does not match GE specifications.
• Sealed system concerns: If the evaporator shows only partial frost and the compressor runs continuously, a sealed system issue is likely and must be handled by an EPA-certified technician.
