How to Fix / Troubleshooting

Immediate action: Press STOP, unplug the microwave, and open the door to ventilate. If flames are present, keep the door closed and unplug; do not open until the fire is out.

Steps:

  • Inspect interior: After cooling, check for burnt food, packaging, or plastic. Remove and clean thoroughly.
  • Check waveguide cover: Inspect the waveguide cover for burn marks or holes. Replace if damaged.
  • Smell from underside: If the smell seems to come from below, the turntable motor or wiring may be overheating. Discontinue use and have it inspected.

Warning: Persistent burning smell without visible food residue indicates a possible internal component failure. Do not continue using the microwave; contact a technician.
