Description

Defrost heater melts frost and ice from the refrigerator's evaporator coils so the cooling system can run efficiently. Replacing a failed heater restores proper defrost cycles and helps prevent frost-related cooling issues. What it does:

• Heats the evaporator to melt accumulated frost and ice on the coils.
• Restores normal airflow and consistent temperatures when frost buildup reduces cooling performance.
• Common symptom linkage: visible frost or ice on the evaporator, long or continuous run cycles, or uneven/warmer compartments.
• Works with the defrost thermostat and control to complete the defrost cycle.

What's included: One defrost heater. Install notes:

• Disconnect power to the appliance before accessing the evaporator or heater — always prioritize safety.
• Handle evaporator fins and the heater element carefully to avoid damage; follow OEM routing and attachment points.
• Verify heater continuity and inspect the defrost thermostat and control before and after replacement; replace any failed defrost components as needed.
