Part WPW10436849 Defrost Heater – Whirlpool Refrigerator
Purpose
Melt frost from evaporator coil
Details
This OEM defrost heater warms the evaporator coil during the defrost cycle, melting accumulated frost so air can circulate freely through the refrigerator and freezer compartments. If the heater fails, frost buildup may occur on the coil, causing poor cooling, warm temperatures, restricted airflow, or ice forming on shelves or vents. Replacing a failed heater restores proper defrost operation and ensures consistent cooling performance. Some sources also associate WPW10436849 with non-heater components; compatibility varies by model—confirm with your model’s diagram before ordering.
