How to Fix / Troubleshooting
Safety first: Disconnect power and allow the oven to cool before accessing the fan.
- Access fan: Remove the internal rear panel of the oven cavity to expose the fan blade.
- Check for debris: Remove any loose screws, food particles, or foil pieces around the fan.
- Tighten blade: Ensure the fan blade nut or screw is tight on the motor shaft.
- Straighten blade: If the blade is slightly bent, carefully straighten it to avoid contact with the shroud.
