Possible Causes
Worn convection fan motor bearings, Loose fan blade, Bent fan shroud contacting blade
How to Fix / Troubleshooting
Safety First: Turn off power and allow the oven to cool completely before accessing the fan.
- Confirm source: Run a convection cycle and listen to locate the noise. If it changes when switching between convection and regular bake, suspect the convection fan.
- Access fan: Remove oven racks and the rear interior panel to expose the convection fan assembly.
- Check blade: Ensure the fan blade is tight on the motor shaft and not rubbing the shroud. Tighten the mounting nut if loose.
- Spin test: Rotate the fan by hand. If it feels rough or wobbly, replace the convection fan motor assembly.
