Burning smell or smoke from the unit during use, not just from food.

Safety first: Turn off and unplug the unit immediately. If you see flames, use a suitable fire extinguisher and do not open the door until flames are out.

• Allow to cool: Wait until the unit is completely cool before opening.
• Clean interior: Remove the basket, tray, and any accessories. Clean the heating element area and interior surfaces with a damp cloth to remove grease and debris.
• Inspect wiring: Open the outer cover and look for burned insulation, melted connectors, or scorched areas around the heater and fan wiring.
• Check element surface: Heavy carbon buildup on the element can cause smoke; gently clean with a non-abrasive pad when cool.
• Replace damaged parts: Replace any burned wiring, connectors, or components such as the heating element assembly or main control board if damage is found.

Do not continue using the appliance if electrical burning smells persist after cleaning; seek professional service.
