La Cornue Worn Convection Fan Motor Bearings

High-pitched squealing or grinding noise from the oven when convection fan is running.

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

Dry or worn motor bearings, Bent fan blade rubbing on shroud, Debris caught in fan, Loose fan mounting screws

Safety first: Disconnect power before removing the fan cover or accessing the motor.

1. Remove fan cover: Take out oven racks and the rear fan cover to access the convection fan.
2. Inspect fan blade: Check for bent blades or contact with the shroud. Straighten or replace the fan blade if damaged.
3. Clear debris: Remove any food particles or foil pieces caught in the fan.
4. Check motor play: Wiggle the fan shaft; excessive play or rough rotation indicates worn bearings. Replace the convection fan motor assembly.
