How to Fix / Troubleshooting
Safety first: Turn off power and allow the oven to cool before inspecting moving parts.
- Identify noise source: Note whether the noise occurs only in convection mode (fan-related) or all modes (could be panels or racks).
- Check racks and panels: Ensure racks are properly seated and not vibrating against each other. Tighten any loose screws on internal panels.
- Inspect fan: Remove the convection fan cover and check for loose screws or debris in the fan blades. Tighten and clean as needed.
- Motor replacement: If the fan motor is noisy or has play in the shaft, replace the convection fan motor.
