Oster air fryer emits a chemical or paint-like odor even after multiple uses.

Safety: Use good ventilation when operating a new fryer. If the odor is very strong or causes irritation, discontinue use.

• Extended burn-in: Run the fryer empty at 375–400°F (190–200°C) for 15–20 minutes several times, allowing it to cool between cycles.
• Clean interior: Wipe all accessible interior surfaces with a damp cloth and mild detergent, then dry thoroughly.
• Inspect for discoloration: Look for areas of paint or plastic that appear scorched. If present, the unit may be overheating and should be inspected by a technician.
• Contact support: If odor persists after several burn-in cycles and cleanings, contact Oster support; replacement may be warranted.
