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

Safety first: Turn off the oven if smoke is heavy. Open windows and use ventilation. Keep a fire extinguisher rated for kitchen use nearby.

Steps:

• Inspect interior: Once cool, remove racks and inspect the bottom and sides for heavy grease or food buildup. Clean with a non-abrasive oven cleaner suitable for Premier ovens.
• Remove foil: Do not line the oven bottom with foil; it traps heat and can cause smoke and damage. Remove any foil from the bottom or racks.
• Burn-off new oven: For a new Premier oven, run an empty bake cycle at 400–450°F for 30–60 minutes with good ventilation to burn off manufacturing residues.
