Possible Causes

Protective coatings on heating element burning off, Residual oils on non-stick basket, Low-quality plastic components near heater, Inadequate initial burn-in

How to Fix / Troubleshooting

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

  • Initial cleaning: Wash the basket and drawer thoroughly with warm soapy water and dry completely.
  • Burn-in cycle: Run the air fryer empty at 200–205°C (390–400°F) for 15–20 minutes, then cool. Repeat 2–3 times if necessary, allowing ventilation.
  • Inspect plastics: If odor persists, inspect interior plastic parts near the heater for discoloration or melting. Replace any deformed components.
  • Stop use if odor is acrid: A sharp, electrical or acrid smell may indicate overheating wiring or components; in that case, discontinue use and inspect wiring and control board.
