Possible Causes
Worn fan motor bearings, Loose fan blade, Foreign object in fan housing, Bent fan blade
How to Fix / Troubleshooting
Safety: Disconnect power. Fans can start unexpectedly if the oven is hot.
- Identify fan: Determine if the noise comes from the convection fan (inside cavity) or the cooling fan (top/rear of cabinet).
- Check for debris: Remove the internal rear panel and inspect the convection fan for loose screws, foil, or food debris. Remove any obstructions.
- Tighten blade: Ensure the fan blade nut is tight on the motor shaft.
- Spin test: Rotate the fan by hand. Roughness or play indicates worn bearings; replace the fan motor assembly.
- Cooling fan: Access the top of the oven and inspect the cooling fan similarly. Replace if noisy or wobbling.
