Oven produces excessive smoke or burning smell during normal baking (not self-clean).

Safety: Ensure good kitchen ventilation. Avoid inhaling heavy smoke; turn off oven if flames appear.

• Initial burn-in: For new ovens, run an empty bake cycle at 400–450°F for 30–60 minutes with windows open to burn off manufacturing residues.
• Clean spills: Once cool, remove racks and clean the oven interior with a non-abrasive cleaner. Remove heavy grease from elements and bottom.
• Avoid foil on bottom: Do not line the oven bottom with foil, as it can trap spills and cause smoke.
