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

Safety First: Ensure good kitchen ventilation. Avoid opening the door rapidly if heavy smoke is present.

• Inspect interior: After the oven cools, remove racks and check the bottom panel and walls for heavy grease or food spills. Clean with a non-abrasive oven cleaner approved for Thor Kitchen ovens.
• Remove foil: Do not line the oven bottom or racks with foil, as this can trap grease and cause smoking.
• Burn-off cycle: For a new oven, run an empty bake cycle at 400–450°F for 30–60 minutes with good ventilation to burn off manufacturing residues.
• Use proper cookware: Use deep pans for fatty foods to prevent drips and splatter.
