Oven produces excessive smoke during normal baking (not self‑clean).

Safety first: Ensure good kitchen ventilation. Turn off the oven if smoke is heavy and investigate before continuing.

• Inspect interior: Once cool, remove racks and check the oven floor and walls for heavy grease or food buildup.
• Clean oven: Use a non‑abrasive oven cleaner or a baking soda paste to clean spills. Avoid getting cleaner on the door gasket or sensor.
• Remove foil: Do not line the oven bottom or racks with foil, as this can trap heat and cause burning.
• Burn off new oven: For a new Avanti oven, run an empty bake cycle at 400–450°F for 30–60 minutes with good ventilation to burn off manufacturing residues.
