Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Frost or ice buildup caused by an open or failed defrost heater
• Reduced airflow or cooling performance when evaporator frost accumulates

Check Before Replacing

• With power disconnected, inspect the heater for visible damage or breakage.
• A continuity test can identify an open heater, but a continuous heater does not rule out a failed defrost thermostat, bi-metal, sensor, or control circuit.
• Verify model-specific compatibility before installation because heater shape and application can vary.
