De Dietrich Dry or Worn Fan Motor Bearings

High-pitched squealing noise from oven during fan 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

Aged convection fan motor, worn cooling fan bearings, misaligned fan shaft

Safety first: Disconnect power before accessing fan assemblies.

Determine which fan: Listen carefully to see if the noise comes from the rear (convection fan) or top (cooling fan).
Inspect fan: Access the suspect fan and spin it by hand. A squeal or resistance indicates bearing wear.
Replacement: Fan motors in De Dietrich ovens are generally not serviceable. Replace the noisy motor assembly with the correct part.
Check alignment: Ensure the fan blade is not rubbing against the housing after installation.
