Frigidaire 5304491703 Refrigerator Defrost Heater

The Frigidaire 5304491703 Defrost Heater for Refrigerator melts accumulated frost from the evaporator area to maintain proper cooling system airflow. This replacement heater is positioned near the evaporator coils and activates during the refrigerator’s automatic defrost cycle, generating heat that removes frost and ice buildup from the coils. Keeping the evaporator clear allows air to circulate properly and supports consistent cooling performance. Replacing a failed or damaged heater can restore the defrost cycle when excessive frost develops or cooling performance becomes inconsistent.
