Possible Causes
How to Fix / Troubleshooting
Safety: Press STOP, unplug the microwave, and if there is visible smoke, ventilate the area. Do not open the door if there is active fire inside; keep it closed and unplug the unit.
Steps:
- 1. Inspect interior: Once cooled, open the door and check for burnt food or splatter. Clean thoroughly.
- 2. Check vents: Ensure external vents are not blocked by dust or objects.
- 3. Smell test: If the burning smell is electrical (sharp, chemical) rather than food, do not use the microwave again until inspected.
Electrical burning smells indicate internal component failure (wiring, control board, magnetron). Have a technician diagnose before further use.
