Excessive smoke or a burning smell from the oven during normal baking (not first use or self-clean).

Safety first: If you see flames, turn off the oven and keep the door closed. If smoke is heavy, ventilate the area.

• Inspect interior: Once cool, check for heavy grease or spills on the bottom, walls, and elements.
• Clean oven: Use the manufacturer-recommended cleaning method. Avoid covering racks or the bottom with foil that blocks airflow.
• Check temperature: Use an oven thermometer to verify the oven is not overheating. If it is, test the temperature sensor and control.
