How to Fix / Troubleshooting
Safety first: Turn off power and allow the oven to cool before inspecting moving parts.
- Identify noise source: Note whether the noise occurs only in fan modes or all modes.
- Inspect fan assembly: Remove the inner rear panel and check the convection fan blade for looseness or contact with the shroud. Tighten the center nut if loose.
- Check cooling fan: Access the top fan and ensure it is securely mounted and free of debris.
- Tighten panels: Tighten any loose screws on side panels, back panel, and trim pieces that may vibrate.
If the fan motor bearings are noisy (grinding or squealing), replace the affected fan motor.
