Possible Causes
Door gasket leak allowing warm air in, Dirty condenser coils, Failed temperature control or thermistor, Low refrigerant charge or weak compressor
How to Fix / Troubleshooting
Safety First: Unplug the freezer before cleaning coils or accessing internal components.
- Step 1 – Check door seal: Inspect the gasket for gaps, tears, or warping. Close the door on a strip of paper in several spots; if it pulls out easily, adjust hinges or replace the gasket.
- Step 2 – Clean condenser: Remove dust and debris from condenser coils to improve heat rejection.
- Step 3 – Verify temperature: Use a thermometer to confirm actual temperature. If normal, long run time may be due to heavy usage or hot ambient conditions.
- Step 4 – Test control/thermistor: On mechanical models, test the thermostat. On electronic models, test the thermistor and replace if out of spec.
- Step 5 – Sealed system check: If the compressor runs constantly but the evaporator shows only partial frost, a sealed system issue is likely and requires a professional technician.
