Possible Causes

Grease-clogged fan guard, Warped or damaged fan blades, Loose fan on motor shaft, Obstructed exhaust duct

How to Fix / Troubleshooting

Safety first: Unplug and let the unit cool before accessing the fan area.

  • Clean fan guard: Remove the basket and look up at the fan guard. Clean off grease and debris with a non-abrasive sponge and mild detergent. Do not bend the guard.
  • Inspect fan blades: Through the guard, check for broken or heavily greased blades. If accessible, remove the upper cover and clean or replace the fan blade assembly.
  • Check fan mounting: Ensure the fan is firmly attached to the motor shaft and not slipping. Tighten the retaining nut or clip if loose.
  • Clear exhaust path: Clean the rear exhaust vents and any internal ducting you can safely access.
