Microwave emits a strong burning, electrical, or plastic smell during or after operation.

Safety First: Stop the microwave immediately and unplug it. Do not inhale smoke directly.

• Inspect interior: Look for burned food, packaging, or plastic. Remove and clean thoroughly.
• Check accessories: Inspect the glass tray, roller ring, and any racks for melting or scorching. Replace damaged parts.
• Listen and observe: If the smell is electrical and accompanied by unusual noises or no heat, a component such as the magnetron or transformer may be failing.
• Do not reuse until inspected: If the source is not clearly food-related, have a technician inspect the internal components for overheating or damage before using the microwave again.
