216730700 Frigidaire Defrost Heater Assembly for Refrigerator/Freezer

Defrost Heater Assembly for Refrigerator/Freezer
Located at the bottom of the evaporator, this component is essential for preventing frost accumulation and ensuring the refrigerator does not overheat. It is compatible with various brands including Frigidaire, Electrolux, and some models from Sears-Kenmore. The defrost heater is an original equipment manufacturer (OEM) part crucial for the defrost system of Frigidaire refrigerators. It functions by melting frost and ice on the evaporator coils, which allows air to circulate properly and maintains the refrigerator’s cooling efficiency.

Potential reasons for the heater's failure may involve a burnt-out heating element, compromised electrical connections of the heater, or issues in the control system that prevent the heater's operation during the defrost cycle.

Indicators of a malfunctioning defrost heater are:

- Frost accumulation on the evaporator coils, which can impede cooling performance.
- An unusually warm freezer or refrigerator compartment.
- Continuous operation of the appliance as it struggles to reach the desired temperature.
- Water or ice accumulation on the freezer compartment's floor, indicating incomplete defrosting.

This defrost heater is also suitable for use with appliances from Gibson, Kelvinator, and certain Kenmore models.
