Oven produces excessive smoke or burning smell during use

Safety first: If you see flames or heavy smoke, turn off the oven and keep the door closed. Use a fire extinguisher rated for grease/electrical fires if needed; never use water on grease fires.

• Initial burn-in (new oven):
  • For new Kenmore ranges, run an empty bake cycle at 400–450°F for 30–60 minutes with good ventilation to burn off manufacturing residues.
• Clean spills:
  • Once cool, remove racks and clean heavy grease or food spills from the oven bottom and walls with a non-abrasive cleaner.
• Check for foil or liners:
  • Remove any foil or liners that may be touching elements or blocking airflow.
• Inspect wiring (if smell is electrical):
  • Turn off power and remove rear panel.
  • Look for melted insulation or burnt connectors near elements and control.
  • Repair or replace damaged wiring and components.
