How to Fix / Troubleshooting
Safety first: Unplug the air fryer before inspection.
- Step 1 – Identify noise source: Run the unit briefly and listen to locate the area of the noise (top, back, side). Then unplug.
- Step 2 – Check for debris: Remove basket/racks and inspect the fan area for loose screws, food pieces, or foil. Remove any obstructions.
- Step 3 – Tighten hardware: With the cover removed, tighten mounting screws for the fan motor, heater bracket, and internal panels.
- Step 4 – Inspect fan blade: Ensure the fan blade is not bent and is firmly secured to the motor shaft. Replace the fan blade if cracked or warped.
- Step 5 – Replace noisy motor: If the noise is a grinding or squealing from the motor itself, replace the convection fan motor.
