Possible Causes
Loose fan blade, food debris caught in fan, worn fan motor bearings, bent fan blade rubbing on shroud
How to Fix / Troubleshooting
Safety: Isolate power and allow the oven to cool before removing the rear panel.
- Access fan: Remove the screws holding the internal rear cover inside the oven to expose the fan blade.
- Clean and tighten: Remove any debris around the fan. Check that the central nut securing the blade is tight. Gently straighten any bent blades.
- Spin test: Spin the fan by hand; it should rotate freely without grinding. If stiff or noisy, the motor bearings are likely worn.
- Replace motor: From the rear of the cooker, remove the fan motor mounting screws and transfer the blade to the new motor. Refit and test.
