How to Fix / Troubleshooting
Safety first: Unplug the unit before removing covers. Allow it to cool.
Steps to reduce noise:
- Identify noise source: Run the unit briefly with an empty basket and listen from different sides to localize the sound (fan area, bottom, sides).
- Inspect fan: Remove the cover to access the fan. Tighten the fan nut or screw if loose. Remove any debris lodged between the fan and shroud.
- Check motor bearings: Spin the fan by hand. Roughness, wobble, or side play indicates worn bearings; replace the motor.
- Tighten hardware: Check all accessible screws on internal panels, heater brackets, and the fan shroud. Tighten any that are loose.
Note: Some airflow noise is normal, but grinding or metallic scraping should be corrected to avoid further damage.
