Strong burning smell or smoke from oven during normal cooking (not first use or self-clean).

Safety first: Turn off the oven if heavy smoke is present. Open windows for ventilation. Avoid inhaling fumes.

• Inspect cavity: Once cool, remove racks and check for heavy grease, spills, or foreign objects on the bottom and near elements.
• Clean thoroughly: Use a non-caustic oven cleaner or a baking soda paste to clean the interior surfaces, racks, and door glass. Avoid spraying directly on elements.
• Check seal: Inspect the door gasket for damage that might allow smoke to escape excessively. Replace if needed.
• Test again: Run the oven empty at a moderate temperature for 20–30 minutes to burn off any remaining residue, with good ventilation.
