How to Fix / Troubleshooting
Safety First: Unplug the freezer before accessing controls or fans.
- Step 1 – Monitor with thermometer: Place a freezer thermometer inside and log temperatures over 24–48 hours.
- Step 2 – Check fan operation: Ensure the evaporator fan motor runs consistently when the compressor is on. Replace if it stops intermittently.
- Step 3 – Inspect sensors: Test the thermistor(s) for stable resistance values. Replace if readings jump or are out of spec.
- Step 4 – Replace control: If sensors and fan are good, the electronic control board may be cycling incorrectly and should be replaced.
