Oven emits a strong burning smell or smoke during normal cooking (not during first use or pyrolysis).

Safety first: If you see heavy smoke or flames, switch off the oven and circuit breaker immediately. Keep the door closed to smother flames and call emergency services if needed.

Step-by-step checks:

• Visual inspection: After cooling, inspect the cavity for burnt food, foil, or plastic on elements or base. Clean thoroughly with appropriate oven cleaner.
• Check elements and wiring: Remove rear cover and inspect for signs of burning on elements, connectors, and wiring. Replace any burnt components.
• Check insulation: Ensure insulation is not touching elements or exposed inside the cavity.

When to call a technician: If the smell is electrical (sharp, acrid) and persists, have a technician inspect the wiring and control board.
