Defrost heater that melts frost from the evaporator coil so the refrigerator can maintain efficient cooling. Replacing a failed heater restores normal defrost cycles and helps prevent ice buildup that blocks airflow. What it does:
- Heats the evaporator coil during the defrost cycle to remove frost and ice buildup.
- Restores proper airflow and cooling when ice accumulation was restricting the evaporator.
- Common symptoms of a failing heater: visible frost or ice on the evaporator, freezer running warm, or extended run times.
- Works with the appliance's defrost thermostat and control to complete the defrost cycle.
What's included: One defrost heater assembly. Install notes:
- Disconnect power to the appliance before servicing to avoid shock or injury.
- Handle the heating element carefully; avoid bending or damaging the coil or terminals.
- Verify the part number matches your appliance before installation.
- If other defrost components (thermostat, control board, sensors) show signs of failure, inspect and replace them as needed.
