How to Fix / Troubleshooting
Safety first: Stop the microwave immediately, open the door, and unplug the unit. If smoke is heavy, ventilate the area.
- Inspect cavity: Look for burnt food, splatters, or packaging that may have ignited. Remove any charred material.
- Check waveguide cover: Examine the cover for burn marks or holes. Replace if damaged.
- Smell source: If the burning smell seems electrical (sharp, chemical) rather than food-related, do not use the microwave again until inspected by a technician.
- Deep clean: Thoroughly clean the interior with a microwave-safe cleaner, then run a short test with a cup of water. If smell persists, internal components may be overheating.
Warning: Do not ignore persistent burning smells; internal fires can occur.
