Is This the Right Part?

✅ Cross Reference Information

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.
