How to Fix / Troubleshooting
Safety first: Turn off power and allow the oven to cool before accessing the fan.
- Check for debris: Remove the rear interior panel and inspect the area around the fan for loose screws, food pieces, or foil. Remove any obstructions.
- Tighten fan blade: Ensure the fan blade nut is tight on the motor shaft. Tighten carefully if loose.
