Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the refrigerator before accessing sensors or fans.
Sensor and fan checks:
- Locate and test the freezer thermistor for proper resistance.
- Inspect the evaporator fan for intermittent operation or loose wiring.
Door seal:
- Check the freezer gasket for gaps that may allow warm air in intermittently.
Repair: Replace a faulty thermistor or evaporator fan motor. If fluctuations persist with good components, the main control board may need replacement.
