Microwave emits a burning smell or smoke from vents during or after use.

Critical safety: Unplug the microwave immediately. If you see flames, do not open the door; unplug if safe and call emergency services if fire persists.

• Check interior:
  • After cooling, open the door and inspect for burned food or packaging.
  • Clean thoroughly.
• Smell source:
  • If the smell is electrical (sharp, chemical), do not use the microwave again until inspected internally.
• Internal inspection (if qualified):
  • Remove the outer cabinet.
  • Look for burned wiring, components, or melted plastic near the magnetron, transformer, or control board.

Any ongoing burning smell without obvious food cause requires professional diagnosis and likely component replacement.
