Loud rattling, grinding, or scraping noise from the air fryer during operation.

Safety first: Unplug the fryer before inspecting internal parts. Do not insert tools or fingers into the fan while powered.

• Identify noise source: Run the unit briefly with an empty basket and listen from different sides to localize the noise (rear, top, side).
• Inspect fan area: Remove the rear cover and fan shroud. Look for screws, foil, or food pieces lodged near the fan.
• Tighten fan blade: If the fan blade is loose on the motor shaft, tighten the retaining nut or screw. If the hub is cracked, replace the fan blade.
• Straighten shroud: If the metal or plastic shroud is bent into the fan path, gently bend it back to provide clearance.
• Check motor bearings: Spin the fan by hand. Roughness, grinding, or side-to-side play indicates worn bearings. Replace the fan motor assembly.
