Possible Causes
Faulty temperature control thermostat or sensor, Blocked air vents by food, Dirty condenser coils, Weak evaporator fan motor
How to Fix / Troubleshooting
Safety first: Unplug the freezer before cleaning coils or accessing fans.
- Verify temperature setting: Ensure the control is set to the recommended setting (often mid-range or 0°F).
- Check loading and vents: Rearrange food so that air vents on the back and sides are not blocked. Avoid packing food tightly against the evaporator cover.
- Clean condenser: Remove the rear lower panel and vacuum the condenser coils and fan blades. Improved airflow can significantly improve cooling.
- Inspect evaporator fan: Open the door while the compressor is running; you should feel strong airflow. If airflow is weak or noisy, replace the evaporator fan motor.
- Test thermostat/sensor: On mechanical models, test the thermostat for continuity when cold. On electronic models, test the thermistor resistance and replace if out of spec.
