Possible Causes

Loose fan blade, Worn motor bearings, Foreign object in fan housing, Loose internal screws or panels

How to Fix / Troubleshooting

Safety first: Unplug and allow the unit to cool before opening. Moving parts can cause injury.

  • Step 1 – Identify noise source: Listen carefully to determine if the noise is from the top (fan/motor) or bottom (vibration against surface).
  • Step 2 – Check placement: Ensure the air fryer is on a stable, level surface. Vibrations can amplify noise.
  • Step 3 – Inspect basket and accessories: Remove the basket and any racks or crisper plates. Run the unit briefly. If the noise disappears, the issue may be with a loose accessory.
  • Step 4 – Internal inspection (advanced): Remove the housing to access the fan. Check that the fan blade is tight on the shaft and not contacting the shroud. Remove any foreign objects.
  • Step 5 – Motor evaluation: If the motor makes grinding or squealing sounds even with the fan removed, the bearings are likely worn and the motor should be replaced.
