How to Fix / Troubleshooting
Safety First: Turn off power before removing any panels. Moving parts can cause injury.
- Identify noise source: Note whether the noise occurs only in convection mode (convection fan) or any heating mode (cooling fan or loose parts).
- Inspect convection fan: Remove the interior rear cover and check the convection fan blade for looseness or contact with the cover. Tighten the mounting nut and reposition if needed.
- Check cooling fan: From the rear, inspect the cooling fan assembly for contact with wiring or insulation. Secure any loose materials.
- Tighten hardware: Tighten any loose screws on internal panels, racks, and supports.
- Replace noisy motor: If the fan motor bearings are noisy or rough when spun by hand, replace the convection fan motor or cooling fan motor as appropriate.
