How to Fix / Troubleshooting

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

Inspection and cleaning:

  • Once cool, inspect the cavity, elements, and fan cover for burnt-on food or grease; clean thoroughly with appropriate oven cleaner.
  • Remove the rear internal panel and check for spills that have reached the fan or ring element.
  • Access the rear of the oven and inspect wiring and insulation around the elements for signs of charring; replace any damaged parts.

If the smell is clearly electrical (sharp, acrid) and not from food, do not use the oven until it has been inspected by a technician.
