FAQs

This defrost heater is compatible with Frigidaire and Kenmore refrigerators. It serves as a direct replacement for OEM part numbers 218169802, 218657302, 449957, 240356221, AP2114071, PS427308, AH427308, and EA427308.
If your refrigerator is failing to cool properly, the most common sign is a buildup of frost or ice on the evaporator coils. If you notice your freezer is warming up or the refrigerator section is not maintaining temperature, the defrost cycle may not be engaging, often due to a burnt-out heater element.
The defrost heater is positioned at the bottom of the evaporator assembly. Its primary function is to heat the evaporator coils during the defrost cycle to melt away any accumulated frost, ensuring proper airflow and cooling efficiency.
Installation is a standard repair that involves accessing the evaporator compartment inside the freezer. You will need to remove the back panel of the freezer to expose the coils. While the process is straightforward, ensure the refrigerator is unplugged before beginning. Most users find they can complete the replacement in about 30 to 60 minutes with basic hand tools.
Yes. If the defrost heater has failed, it is wise to test the defrost thermostat and the defrost timer (or control board) as well. If the thermostat is faulty, it may prevent the heater from receiving power even if the heater itself is in good condition.
