Microwave emits a burning smell, chemical odor, or smoke during operation.

Emergency safety: Press Stop/Cancel immediately and unplug the microwave. If there is visible fire inside, keep the door closed to smother flames and call emergency services if needed.

Steps after it is safe:

• Inspect interior: Look for burned food, packaging, or plastic. Remove and clean thoroughly.
• Check vents: Ensure all vents are clear of dust and obstructions.
• Do not reuse if smell is electrical: If the odor is sharp, chemical, or like burning insulation, do not use the microwave again until inspected.

Service:

• A technician should inspect internal wiring, the magnetron, and the high-voltage circuit for overheating or damage.
