The Whirlpool WPW10128551 Evaporator Fan Motor helps maintain consistent cooling by circulating cold air throughout the refrigerator. Designed for compatible refrigerator models, this motor powers the evaporator fan, which moves chilled air from the evaporator area into the refrigerator and freezer compartments. Proper airflow helps distribute temperatures more evenly and supports efficient cooling of stored food. A functioning fan motor can also help prevent warm spots and reduce cooling inconsistencies caused by poor air circulation. This replacement part is suitable for addressing symptoms such as a noisy fan, weak airflow, or a refrigerator that is not cooling properly.
