Gaggenau Electrical or fan-related noise

Oven makes a high-pitched whining or humming noise 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, Vibrating transformer or inductor on control board, Loose metal panel resonating with fan

Safety: Disconnect power before tightening panels or accessing internal parts.

Localize noise: Listen carefully to determine if the noise comes from the fan area, control panel, or rear.
Tighten panels: Tighten mounting screws on side, top, and rear panels to reduce vibration.
Fan inspection: Check fan motors for bearing noise by spinning them by hand when power is off. Replace noisy motors.

Note: A faint hum from transformers is normal, but loud or changing pitch noises may indicate impending component failure.
