Possible Causes
Failed defrost heater, Open defrost thermostat, Defective defrost control on main board, Evaporator fan running but airflow blocked by ice
How to Fix / Troubleshooting
Safety First: Unplug the refrigerator before removing freezer panels or using any heat source.
- 1. Check airflow: Place your hand near the fresh food air vents; weak or no airflow with a cold freezer suggests frost blockage.
- 2. Inspect evaporator: Remove freezer drawers and rear panel. If the evaporator coil is a solid block of ice, the defrost system has failed.
- 3. Manual defrost: Unplug the unit and leave doors open for several hours, using towels to catch water. This will temporarily restore cooling.
- 4. Test defrost components: With a multimeter, test the defrost heater and defrost thermostat for continuity. Replace any open components with Frigidaire Professional‑approved parts.
- 5. Control board: If heater and thermostat are good, the main control board may not be initiating defrost and may need replacement.
