W11780227 Whirlpool Refrigerator Evaporator Fan Motor – Fix Your Fridge That Won't Cool, Has Frost Buildup, or Makes Loud Humming Noise
The W11780227 is the current OEM evaporator fan motor for a wide range of Whirlpool, KitchenAid, Maytag, Amana, and Kenmore side-by-side and top-mount refrigerators. This motor drives the fan blade that circulates cold air across the evaporator coils and throughout the refrigerator and freezer compartments. When it fails, cooling stops — food warms up, frost accumulates unevenly, and you may hear a loud hum or grinding from the freezer section.

✓ Installation Tips
Unplug the refrigerator before beginning any repair. Access the evaporator fan by removing the freezer back panel — typically held by 2–4 screws. Disconnect the wire harness from the old motor, remove the fan blade, and transfer it to the new motor. Reconnect the harness, reinstall the panel, and plug the refrigerator back in. Allow 24 hours for temperatures to stabilize. Most installations take 20–45 minutes with basic tools.
