Strong chemical or plastic smell from a relatively new air fryer that does not diminish after several uses.

Safety first: Ensure good ventilation when performing burn-in cycles.

• Initial burn-in: Run the air fryer empty (or with a small amount of water in a pan if recommended) at a high temperature for 15–20 minutes, then cool. Repeat 2–3 times to burn off manufacturing residues.
• Inspect basket and tray: Check the non-stick basket and tray for peeling or blistering coating. Replace if damaged.
• Check plastic parts: Look for warped or discolored plastic near the heater. Replace affected trim or shields.
• Improve ventilation: Operate the unit in a well-ventilated area away from walls and cabinets.

If the smell remains strong and chemical after multiple burn-in cycles, discontinue use and contact Breville or a service center.
