KitchenAid Noisy Convection or Cooling Fan

Oven fan is very loud, rattling, or grinding during operation

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn fan motor bearings, loose fan blade, debris in fan housing, bent fan blade

Safety: Disconnect power before accessing fans.

Identify fan: Determine if the noise is from the convection fan (inside cavity) or cooling fan (behind control).
Inspect blades: Check for loose screws, bent blades, or foreign objects contacting the fan.
Spin test: Rotate the fan by hand; roughness or play indicates worn bearings.

Replace the noisy fan motor assembly. Ensure all mounting screws are tight to prevent vibration.
