GE Refrigerator: not defrosting
What is this symptom?
Is your GE refrigerator not defrosting? This common issue results in frost or ice buildup on evaporator coils, leading to blocked airflow and diminished cooling performance. The automatic defrost cycle may be malfunctioning, preventing proper temperature regulation in both the freezer and refrigerator compartments.
Possible Causes
Defrost heater failure
How to Identify: Evaporator coils remain covered in frost or ice; multimeter continuity test shows open circuit on the defrost heater; fridge runs but coils stay frozen.
Part: Defrost heater assembly
Defrost thermostat (termination thermostat) fault
How to Identify: Thermostat does not close at low temperatures when tested; frost remains because heater doesn't receive power; located near evaporator coil.
Part: Defrost thermostat
Defrost timer or defrost control board failure
How to Identify: Refrigerator never enters defrost cycle; manually advancing timer does not engage heater; control board may show signs of failure or no signal to defrost components.
Part: Defrost timer / defrost control board
Clogged defrost drain
How to Identify: Ice or water pooling at bottom of freezer; water doesn’t drain during defrost; frost buildup recurs quickly after manual defrost.
Part: Defrost drain tube
