This evaporator defrost heater melts frost and ice buildup on the evaporator coils so the refrigerator can maintain proper cooling. It replaces a failed heater to restore normal defrost operation and help prevent over-icing. What it does:
- Heats the evaporator coil during the defrost cycle to melt accumulated frost and ice
- Helps restore normal airflow and cooling when frost is blocking the coil
- Commonly associated with symptoms like excessive frost buildup, reduced cooling, or the freezer running constantly
- Works with the appliance's defrost controls (thermostat/timer/board) to operate only during defrost cycles
