Common Symptoms
- Visible frost or ice accumulation on the freezer’s rear evaporator cover
- Refrigerator or freezer compartment warming because airflow is restricted by frost
- Refrigerator running for unusually long periods
- Food warming despite normal temperature settings
Check Before Replacing
- Disconnect electrical power before inspection.
- Look for an unusually thick frost or ice layer on the evaporator cover or evaporator area; this indicates a defrost-system issue but does not by itself prove heater failure.
- With power disconnected and the evaporator area safely accessible, inspect the heater’s glass element, terminals, and wiring for visible breakage, scorching, or loose connections.
- If qualified to use a multimeter, test heater continuity only with the appliance unplugged and the heater isolated as required by the model’s service procedure; an open circuit supports heater failure, but other defrost components can produce similar symptoms.
Pro Tip
A failed defrost heater is only one possible cause of frost-related cooling problems; the defrost thermostat, timer, control, wiring, and airflow should also be evaluated before replacing the heater.

Installation Notes
- Unplug the refrigerator before installation.
- Access to the evaporator and removal of the evaporator cover may be required.
- Allow accumulated ice to clear safely before attempting to remove the heater; do not pry against or damage the glass element, evaporator, wiring, or refrigerant tubing.
- Disconnect the heater wiring before removing the old assembly and confirm that the replacement is seated securely in its original supports before reassembly.
- Verify the exact refrigerator model and part number before installation because visually similar heaters can differ in size or shape.
