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

Safety first: If you see heavy smoke or flames, switch off the oven and mains supply immediately. Keep the door closed to smother flames.

Step-by-step checks:

• 1. Inspect cavity: Once cool, check for burnt-on food or grease on elements and cavity surfaces. Clean thoroughly with appropriate oven cleaner (avoid spraying directly on elements).
• 2. Check elements: Look for glowing hot spots or deformation when the oven is on (qualified person only). Replace any suspect element.
• 3. Inspect wiring: Remove rear and top covers to check for scorched insulation or melted connectors. Repair or replace damaged wiring.
• 4. Verify ventilation: Ensure vents are not blocked by foil or cabinetry.

Warning: Persistent burning smell after cleaning indicates a component fault that should be investigated before further use.
