How to Fix / Troubleshooting
Safety: Unplug the microwave immediately if you smell burning plastic or insulation. Do not continue to use it.
User checks:
- Inspect the interior for burnt food or splatters on the cavity walls, ceiling, and turntable.
- Clean thoroughly and run a short test with a cup of water. If the smell persists, stop using the unit.
Persistent electrical or plastic burning smells usually indicate internal component failure and require professional inspection of the magnetron, transformer, wiring, and control board.
