Oven emits a burning smell or smoke during normal cooking (not first use or self-clean).

Safety first: If you see heavy smoke or flames, turn off the oven and power at the breaker immediately. Keep the door closed to smother flames and call emergency services if needed.

Steps to investigate:

• Inspect cavity: Once cool, remove racks and check for heavy grease or food residue on the elements and cavity surfaces. Clean thoroughly with an oven-safe cleaner.
• Check elements: Look for localized glowing spots or cracks on elements during operation (observe through the door). Replace any element with visible damage.
• Inspect wiring: Remove rear and top panels to check for wiring that has fallen onto or too close to hot surfaces. Re-route and secure with high-temperature clips; replace any burnt insulation.
• Verify cooling fan operation: Ensure the cooling fan runs during high-temperature use. Replace the fan motor if it does not operate.
• Test: After cleaning and repairs, run the oven empty at a moderate temperature to burn off any remaining residue and confirm that the smell does not return.
