Oven emits a strong chemical or burning plastic smell during use.

Safety first: If you see smoke from control area or smell electrical burning, turn off power immediately and do not use the oven.

• New oven burn-in: For new units, run an empty bake cycle at high temperature (per manual) with good ventilation to burn off residues.
• Remove foreign materials: Check for any plastic, foam, zip ties, or cardboard left in the oven or storage drawer and remove them.
• Inspect behind control panel: If the smell is electrical, disconnect power and remove the rear panel to inspect wiring and the control board for signs of overheating or melting. Replace any damaged wiring or the EOC.
• Stop use if unsure: If you cannot identify the source, discontinue use and contact a technician.

Warning: Do not ignore persistent burning smells; they can indicate a fire hazard.
