How to Fix / Troubleshooting
Safety: Turn off and unplug the microwave at the first sign of burning or electrical smell.
User-level checks:
- Inspect and clean the interior cavity, turntable, and waveguide cover to remove all burnt food and grease.
- Run the microwave with a cup of water for a short time and monitor for smell (do not leave unattended).
If the smell persists or seems electrical (sharp, plastic-like), discontinue use and have a technician inspect internal components such as the magnetron, transformer, and wiring.
