How to Fix / Troubleshooting

Safety: Unplug the air fryer and allow it to cool. Do not touch the fan while it is spinning.

  • Check for loose items:
    • Remove basket and pan.
    • Look up at the fan guard for trapped food, foil, or parchment; remove carefully with long tweezers.
  • Access fan assembly (advanced):
    • Remove the top or rear cover to expose the fan.
    • Inspect blades for bending or cracks; gently straighten minor bends.
    • Tighten any loose fan mounting nut or screws.
  • Assess motor bearings:
    • Spin the fan by hand; roughness, grinding, or side play indicates worn bearings.
  • Replace parts: Replace the fan motor assembly if bearings are noisy or seized. Replace the fan blade if cracked or badly deformed.
