Description

This defrost heater melts frost and ice buildup on the evaporator to restore normal airflow and cooling performance in frost-free refrigerators. It replaces a failed heater to help prevent excessive frost accumulation and compressor overwork. What it does:

• Heats the evaporator coil during defrost cycles to remove frost and ice.
• Helps restore proper airflow and temperature consistency in the freezer compartment.
• Commonly replaced when the freezer has heavy frost buildup or reduced cooling.
• Works as part of the refrigerator's automatic defrost system; not a standalone thermostat or control.

What's included:

• One defrost heater assembly.

Install notes:

• Disconnect power to the appliance before servicing to avoid electric shock.
• Access typically requires removing the evaporator cover/panel in the freezer; follow the OEM service manual.
• Inspect wiring and connectors for heat or corrosion damage and replace any compromised components.
• If defrost issues persist after replacement, check the defrost thermostat, timer/control board, and sensors per OEM troubleshooting.
