Oven emits a strong chemical or burning plastic smell during use, even after several cycles.

Safety first: If you smell burning plastic or see smoke from vents, turn off the oven and breaker immediately.

• Initial burn-in (new ovens): For new LG Studio ovens, run an empty cycle at 400–450°F for 30–60 minutes with good ventilation to burn off manufacturing residues.
• Check for packaging: Once cool, inspect inside the oven, under racks, and behind panels for any leftover plastic, foam, or tape.
• Inspect rear components: With power OFF, remove the rear panel and look for discolored or melted wiring, especially near elements and fans.
• Replace overheated parts: If you find melted insulation or a burnt odor near a specific component (e.g., fan motor), replace that part and any damaged wiring.

Warning: Do not continue using the oven if you suspect electrical overheating; this is a fire hazard.
