Burning smell or smoke from oven during normal cooking (not first use or cleaning).

Safety first: Turn off the oven and, if smoke is heavy, switch off at the mains. Do not ignore persistent burning smells.

Steps to check:

• Inspect cavity: Once cool, check for food or grease on elements or oven base. Clean thoroughly with appropriate oven cleaner.
• Check elements: Look for hotspots, glowing unevenly, or damaged sheathing on elements. Replace any suspect elements.
• Rear inspection: Remove the rear panel and inspect wiring for signs of overheating or melted insulation. Repair or replace damaged wiring.
• Ventilation: Ensure vents are not blocked and that the cooling fan operates correctly.
• If smell persists without visible cause: Have the cooker inspected by a qualified engineer to rule out internal electrical faults.
