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

Safety first: Turn off the oven immediately if you see flames or heavy smoke. Keep the door closed to smother flames and disconnect power.

• Inspect cavity: Once cool, inspect for heavy grease or carbon deposits. Clean thoroughly with an appropriate oven cleaner.
• Check elements: Look for hot spots, blisters, or cracks on elements that may indicate imminent failure.
• Inspect wiring: Remove rear panel and check for burned insulation or melted connectors. Replace any damaged wiring and connectors.
• Test operation: Run the oven empty at a moderate temperature to burn off remaining residues while monitoring for smells.
