Oven emits a burning plastic or electrical smell during use.

Safety first: If you suspect an electrical burning smell, turn off power at the breaker immediately and do not continue using the oven until inspected.

• New oven burn-in: For new installations, some odor is normal during the first few uses. Run the oven empty at 400–450°F for 30–60 minutes with good ventilation.
• Inspect wiring: With power off, remove the rear panel and inspect wiring near the elements, terminal block, and control board for melted insulation or burn marks. Repair or replace damaged wiring.
• Check for foreign objects: Inspect the oven cavity for plastic utensils, packaging, or liners that may have fallen onto the element and remove them.
• Terminal block: Tighten any loose connections at the power terminal block; heat from arcing can cause burning smells.

Warning: Persistent electrical odor indicates a serious problem. If you are not experienced with electrical repairs, contact a professional.
