ENDMAN Refrigerator Defrost Control Board 5303918476 / 241508001 — Direct-fit replacement, restores automatic defrost

ENDMAN 5303918476 is a direct-fit refrigerator defrost control board designed to restore automatic defrost cycles for compatible Frigidaire, Kenmore, and Electrolux models.

If your refrigerator is building up frost, running unusually cold in the freezer, or the defrost timer no longer advances, the control board that coordinates the defrost cycle may be failing. This ENDMAN replacement board matches common OEM part numbers and is sized to fit typical control housings so you can replace the electronic module without modifying the shell.

How does this control board fix defrost cycle problems?

The defrost control board governs when the compressor and defrost heater switch between cooling and defrost modes. Replacing a faulty board restores the timing and electronic switching that allow scheduled thawing of the evaporator coils. That helps reduce ice buildup that impairs airflow and cooling efficiency.
