Whirlpool Whirlpool WRS331SDHM 21 cu. ft. Side-by-Side Refrigerator 2 Error Fix: Defrost Heater Failure

Diagnostic flash code: the defrost heater has failed (open circuit). The defrost heater is a glass tube or metal element mounted on or near the evaporator coils inside the freezer. During defrost, it heats the coils to melt accumulated frost. A failed heater causes the evaporator to ice over completely, blocking airflow and making the refrigerator and freezer warm up gradually. Test the heater for continuity — it should show some resistance. An infinite reading means open circuit. Replace the defrost heater.
