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

Safety first: If heavy smoke appears, switch off the oven and open windows. Do not leave the oven unattended.

• Inspect interior: Once cool, remove racks and check for heavy grease or food deposits on elements and cavity surfaces. Clean with appropriate oven cleaner (avoid spraying directly on elements or sensors).
• Check for plastic or packaging: Ensure no plastic trays, films, or packaging have been left inside.
• Inspect wiring: If the smell is electrical (sharp, acrid), disconnect power and inspect internal wiring and insulation for signs of overheating. Replace any burnt components.
• Verify temperature control: If food burns quickly at normal settings, test the thermostat/sensor and control board as per overheating fault procedures.
