Smeg oven emits a burning smell or smoke during normal cooking (not first use).

Safety first: If you see heavy smoke or suspect an electrical burning smell, switch off power immediately and do not use the oven until inspected.

• Inspect cavity: When cool, remove shelves and check for heavy grease or food deposits on elements, walls, and floor. Clean thoroughly with appropriate oven cleaner (avoid spraying directly on elements or sensors).
• Check around elements: Inspect areas around the grill and bottom elements for burnt-on residue. Carefully clean without bending elements.
• Ventilation: Ensure vents are not blocked and that the cooling fan operates correctly.
• Electrical smell: If the smell is sharp and chemical (insulation burning), remove the oven and inspect wiring, especially near elements and the control board. Replace any burnt wiring or components and investigate cause of overheating.
