Persistent plastic or chemical smell from a new or lightly used air fryer.

Safety first: Ensure good ventilation when performing burn‑in.

• Initial cleaning: Wash the basket and pan with warm soapy water and dry thoroughly.
• Burn‑in cycle: Run the air fryer empty at a high temperature (e.g., 200°C) for 10–15 minutes, then allow to cool. Repeat once or twice if needed.
• Inspect for trapped packaging: Check around the heater and fan area for any leftover plastic films, cable ties, or cardboard. Remove any foreign materials.
• Ongoing smell: If the smell persists after several uses and cleanings, inspect the heater and internal plastics for signs of overheating or melting. Replace any deformed parts and verify temperature control is functioning correctly.
