Whirlpool Refrigerator Evaporator Motor (W11578030)

The Whirlpool Refrigerator Evaporator Motor drives the evaporator fan inside the freezer compartment, pulling air across the evaporator coils and circulating cold air throughout both the freezer and fresh food sections. This fan motor keeps temperatures consistent by moving refrigerated air continuously while the compressor runs, making it a core part of your refrigerator's cooling system.

The Whirlpool Refrigerator Evaporator Motor can fail from normal wear over time, ice buildup that jams the fan blade, or electrical issues within the motor windings or harness. A damaged or seized motor will reduce or stop airflow entirely, causing the refrigerator to lose its ability to maintain proper temperatures even when the compressor is still running.

These symptoms may point to a failing evaporator fan motor in your refrigerator:

- Refrigerator or freezer not staying cold enough

- Loud humming, buzzing, or squealing noise from inside the freezer

- Fan blade spinning slowly or not spinning at all

- Frost or ice buildup around the evaporator fan area

- Refrigerator running constantly without reaching set temperature

- Fresh food section warm while freezer stays cold

- No airflow felt when the freezer door is open
