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

Safety: If you see heavy smoke or smell burning plastic, switch off the oven and disconnect power immediately.

• Inspect cavity: Once cool, remove racks and trays. Check for grease or food spills on the bottom, near elements, and on the fan cover. Clean thoroughly with an oven-safe cleaner.
• Check elements: Look for hot spots or glowing areas on elements that differ from the rest; this can indicate impending failure.
• Wiring inspection: Remove the rear cover and inspect wiring and connectors for signs of overheating or melting. Replace any damaged parts.
• Fan motor: If the smell is strongest near the top/rear, the fan motor may be overheating. Replace if insulation smell persists.
• Test: Run the oven empty at moderate temperature for 20–30 minutes with good ventilation to burn off any remaining residue.
