Oven emits a persistent chemical or plastic smell even after several uses.

Safety first: Ensure good kitchen ventilation when running the oven at high temperatures.

Steps:

• Confirm that all packaging, stickers, and plastic films have been removed from inside and outside the oven.
• Run the oven empty at 200–250°C for 1–2 hours with good ventilation to burn off manufacturing residues (if not already done).
• Inspect inside for any foreign objects or melted plastic; remove carefully.
• If the smell persists and seems electrical or plastic-burning, disconnect power and have the wiring and insulation inspected by a technician.
