Oven produces excessive smoke or burning smell during normal baking

Safety first: Ensure good kitchen ventilation. If smoke is heavy, turn off the oven and open windows.

• Inspect interior:
  • Check for heavy grease buildup or spills on the bottom, walls, and elements.
• Clean oven:
  • Use the oven's self-clean cycle if safe to do so, or manually clean with appropriate oven cleaner (avoid spraying directly on door gasket or sensor).
• Check liners:
  • Remove any foil or aftermarket liners that may be touching elements or blocking airflow.
• Door gasket:
  • Inspect and replace the oven door gasket if smoke is escaping around the door edges.
