Frigidaire 5303918255 Defrost Heater Assembly for Refrigerator

The Frigidaire 5303918255 Refrigerator Defrost Heater Assembly generates controlled heat to melt frost accumulated on the evaporator coil during the defrost cycle. It is fitted directly around or beneath the evaporator coil inside the freezer compartment and connected to defrost circuit through the wiring harness and control system. It operates under timed or sensor-based control to activate heating elements when frost buildup is detected. The component maintain clear ice formation restores proper airflow across the evaporator and supports consistent cooling efficiency and temperature regulation during regular refrigeration and automatic defrost operation cycles.
