How to Fix / Troubleshooting

Safety first: Disconnect power before removing panels.

Identify noise source: Run the oven briefly (with panels in place) to locate the general area of the noise, then switch off and isolate.
Check convection fan: Remove the rear internal panel and inspect the fan blade. Tighten the central nut and ensure the blade is not bent or rubbing the shroud.
Inspect cooling fan: Access the top rear fan and check for loose mounting screws or contact with the casing.
Tighten panels: Tighten any loose screws on side, rear, and top panels that may vibrate.
Replace noisy motor: If the fan motor is noisy due to worn bearings, replace the motor assembly.

Oven makes loud rattling, scraping, or humming noises during operation, especially in fan modes.
