Whirlpool WPW10316428 Defrost Heater Assembly for Refrigerator

The Whirlpool WPW10316428 Refrigerator Defrost Heater Assembly is responsible for melting ice that accumulates on the evaporator coils, which helps prevent frost buildup. It operates during the defrost cycle by generating heat to thaw the frozen coils, allowing for proper airflow within the refrigerator. This process maintains consistent cooling performance by reducing excessive frost that could impede efficiency. The assembly is constructed for durability and contributes to energy efficiency while supporting the longevity of internal components. Proper defrosting also minimizes strain on the compressor, which aids in regulating temperature and can lower energy consumption. Replacing a malfunctioning defrost heater with this assembly helps restore the refrigerator's cooling capabilities and prevents food spoilage.
