Common Causes
- 1Defrost heater burned out
- 2Defrost thermostat open

Step-by-Step Troubleshooting

Unplug unit and remove freezer back panel to inspect evaporator coils
- 2
Check for heavy frost/ice on evaporator — confirms defrost heater is not firing
- 3
Test defrost heater continuity with multimeter (expect 20-40 ohms)
- 4
Test defrost thermostat — should be closed (continuity) when cold
- 5
If heater and thermostat test good, the main board defrost relay has failed
