How to Fix / Troubleshooting
Safety first: Press STOP/CANCEL, open the door carefully to vent smoke, and unplug the microwave. If flames are present, follow fire safety procedures and do not open the door until the fire is out.
Steps to try:
- Identify source: Once safe and cool, inspect inside for burnt food, packaging, or plastic containers that may have melted.
- Clean thoroughly: Remove all residue and clean the cavity with mild detergent. Remove and clean the turntable and roller ring.
- Check exterior vents: Ensure vents are not blocked and filters are clean.
- Test briefly: After cleaning and airing out, run a short test with a cup of water. If burning smell persists without any food, stop using the unit.
- Service: A technician should inspect internal wiring, fan motor, and magnetron for overheating or insulation damage.
