Unusual chemical or plastic smell when the air fryer is used.

Safety first: If the smell is strong or accompanied by smoke, unplug immediately.

• Initial curing: For a new Hisense air fryer, run an empty cycle at medium temperature for 10–15 minutes with good ventilation to burn off manufacturing residues.
• Inspect interior: Ensure only original Hisense basket and accessories are used. Remove any non-heat-resistant liners or containers.
• Check for melted plastic: Inspect the area around the heater and fan for warped or melted plastic parts. Replace any deformed components.
• Inspect wiring: Open the cover and look for discolored or brittle wire insulation near hot areas. Reroute or replace wiring as needed.
• Stop use if smell persists: Persistent strong chemical smell may indicate internal overheating; discontinue use and seek professional service.
