Description

This defrost heater melts frost and ice buildup on the evaporator so a frost-free refrigerator can complete its automatic defrost cycle and maintain normal cooling. Designed to replace a failed evaporator heater and restore proper defrost operation. What it does:

• Heats the evaporator during the defrost cycle to remove frost and ice buildup.
• Helps restore normal cooling when frost accumulation prevents efficient airflow.
• Common symptoms: visible frost/ice on evaporator, freezer running longer than normal, or heat element showing open continuity.
• Works with the refrigerator's defrost control and thermostat to run only during defrost cycles.

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

• Disconnect power to the appliance before servicing to avoid shock risk.
• Access may require removing the evaporator cover; follow the manufacturer's service instructions.
• Handle the element and evaporator fins carefully to avoid damage; secure heater with original clips or fasteners.
• Test for continuity before and after installation and confirm proper defrost cycle operation once reassembled.
