Oven produces excessive smoke during normal baking (not self-clean), often from the vent or door edges.

Safety first: If smoke is heavy, turn off the oven, open windows, and keep the door closed to limit oxygen until smoke subsides.

Steps to reduce smoke:

• Cool and clean: Once cool, remove racks and clean the oven interior with a non-caustic cleaner. Remove heavy carbon deposits and grease.
• Avoid foil on bottom: Do not line the oven bottom with foil; it can trap spills and block vents.
• Use drip pans: For high-fat foods, place a tray under the food to catch drips.
• Burn-off cycle: After cleaning, run the oven empty at 400°F for 20–30 minutes to burn off remaining residues, with good ventilation.

Note: Persistent smoke without visible spills may indicate a failing element or wiring insulation burning; inspect elements and wiring if odor is electrical.
