How to Fix / Troubleshooting
Safety First: Unplug and cool the unit before accessing the fan area.
Step-by-step checks:
- Identify source: Listen carefully to determine if the noise comes from the fan area (top) or control area.
- Inspect fan: Remove the basket and look at the fan. Check for contact between blades and housing.
- Adjust shroud (advanced): With the cover removed, gently adjust the fan shroud if it is touching the blades.
- Replace motor: If the noise is clearly from the motor and persists, replace the convection fan motor assembly.
Note: Some faint electrical whine is normal with PWM motor control, but loud squealing indicates a mechanical issue.
