How to Fix / Troubleshooting

Safety first: Unplug the appliance before removing interior panels or touching the fan.

  • 1. Identify noise source:
    • Open the door briefly while the noise is present to confirm it comes from inside the cabinet.
  • 2. Access fan assembly:
    • Remove shelves and the rear interior panel to expose the evaporator fan.
  • 3. Inspect for obstructions:
    • Look for ice, wiring, or insulation contacting the fan blades.
    • Clear any obstructions and secure loose wires.
  • 4. Check fan bearings:
    • Spin the fan by hand; if it feels rough or wobbly, the motor is worn.
  • 5. Tighten mounts:
    • Ensure the fan housing and motor screws are tight.
  • 6. Replace fan motor:
    • If noise persists and the motor is worn, replace with the correct Miele evaporator fan motor.
