Whirlpool WP61002045 Defrost Heater for Refrigerator

The Whirlpool WP61002045 Refrigerator Defrost Heater functions to reduce frost accumulation inside the refrigerator. During the defrost cycle, this heater activates to melt any ice that has formed on the evaporator coil. These coils take in heat from the interior of the refrigerator, which helps keep food cool. If frost builds up on the coils, it can insulate them, reducing their effectiveness and causing the refrigerator to work harder to maintain the desired temperature. This can lead to increased energy costs and may impact the appliance's performance. The WP61002045 serves as a replacement for a faulty defrost heater, restoring the defrosting capability and assisting in maintaining proper food storage conditions.
