How to Fix It
1
Remove the back panel inside the freezer to inspect the evaporator coils for heavy frost or ice
2
If heavily frosted, this confirms a defrost system failure; manually defrost by unplugging for 12-24 hours
3
Test the defrost heater for continuity with a multimeter (should be 20-50 ohms)
4
Test the defrost thermostat (bi-metal) for continuity when cold (should be closed below 15 degrees F)
5
If both test good, replace the defrost control board or timer
