Unit is unusually loud compared to when it was new.

Safety first: Unplug and cool the unit before opening.

• Relocate unit: Place a silicone mat under the air fryer to reduce resonance and vibration noise.
• Clean fan area: Remove debris and grease from the fan and shroud.
• Tighten hardware: Tighten all accessible screws on the housing and internal brackets.
• Replace fan motor: If noise is clearly from the motor and persists, install a new fan motor.
