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

Loose fan blade, worn fan motor bearings, debris caught in fan, bent fan blade

Safety first: Disconnect power before accessing the fan.

Identify noise source: Run the oven briefly and listen to locate whether the noise is from the rear (convection fan) or top (cooling fan).
Inspect fan blade: Remove the rear cavity panel and check for loose screws or debris around the fan.
Check bearings: Spin the fan by hand; roughness or play indicates worn bearings.
Tighten or replace: Tighten the fan fixing nut/screws. Replace the fan motor if noisy or loose.
