Common Symptoms
- Heavy frost or an ice sheet behind the freezer’s rear panel
- Reduced airflow from evaporator frost blockage
- Fresh-food section warming while the freezer remains comparatively cold
- Refrigerator running for extended periods due to restricted evaporator airflow
Check Before Replacing
- Disconnect electrical power before accessing or testing the heater.
- Visually inspect the glass heating elements for breakage, scorching, or other damage.
- With power disconnected and the heater isolated according to the model’s service procedure, check the heater for electrical continuity; an open circuit indicates the heater cannot operate, but other defrost-system components may produce similar symptoms.
- Inspect the defrost thermostat, thermal fuse, wiring, and connectors because a heater symptom does not by itself identify the failed component.
- Confirm that the replacement’s element length, connector arrangement, and mounting configuration match the removed assembly.
Pro Tip
Do not diagnose the heater from frost buildup alone; verify the heater circuit and inspect the defrost thermostat, fuse, wiring, and controls before replacing the assembly.
