Oven or cooktop emits a strong burning smell or smoke during normal cooking (not first use).

Safety: If you see flames or heavy smoke, turn off the appliance, keep the door closed, and ventilate the area. Do not use water on grease fires.

• Inspect interior: Once cool, check for heavy grease or food spills on the oven floor, racks, and elements. Clean with appropriate oven cleaner.
• Check cooktop: Clean burnt-on spills from around burners and under grates. Ensure no plastic items are near hot zones.
• Electrical smell: If the odor is chemical or like burning insulation, disconnect power and inspect wiring and control boards for discoloration or melting. Replace any damaged components.
• First-use burn-off: New ovens may smell for the first 1–2 uses; run an empty cycle at high temperature with good ventilation to burn off manufacturing residues.
