Oven emits a strong burning smell or smoke during normal use (not first-time burn-in).

Safety first: If you see heavy smoke or suspect an electrical burning smell, switch off the oven and power immediately.

Steps to check:

• Once cool, inspect the cavity, elements, and fan cover for burnt-on food or grease; clean thoroughly with oven-safe cleaners.
• Pull the oven out and inspect the rear for signs of burned wiring or melted plastic, especially near the terminal block and elements.
• Check that the cooling and convection fans operate correctly to prevent hotspots.
• If the smell is clearly electrical (sharp, acrid), do not use the oven until a technician inspects and repairs any overheated components.

Warning: Do not operate the oven with suspected electrical faults; risk of fire.
