Possible Causes
Defective temperature control thermostat (mechanical models), Failed thermistor, Control board not cycling compressor off, Temperature set too low
How to Fix / Troubleshooting
Safety: Unplug the freezer before accessing controls.
Steps:
- Adjust temperature: Set the control to a warmer setting and monitor for 24 hours.
- Mechanical thermostat models: If the compressor runs constantly regardless of knob position (including "off"), replace the temperature control thermostat.
- Electronic models: Test the cabinet thermistor and replace if out of spec. If the thermistor is good but the compressor never cycles off, replace the electronic control board.
- Check door gasket: A leaking gasket can cause the unit to run excessively and build frost; replace if damaged.
