Possible Causes
How to Fix / Troubleshooting
Safety: If the smell is strong or accompanied by smoke, unplug the microwave immediately and do not use it until inspected.
Steps:
- 1. Inspect interior: Look for burnt food, melted plastic, or discoloration on the cavity walls, turntable, and roller ring. Clean thoroughly.
- 2. Test with water only: After cleaning and cooling, heat a cup of water. If the burning smell persists with no food inside, an internal component may be overheating.
Advanced: A technician can inspect the magnetron, transformer, fan motors, and wiring for heat damage or burning. Replace any overheated components with Sharp-approved parts.
