How to Fix / Troubleshooting
Safety first: Stop the microwave immediately, open the door, and unplug the unit. If you see smoke or flames, follow fire safety procedures and do not open the door until the fire is out.
Inspection:
- After cooling, inspect the interior for burned food, melted plastic, or charred packaging; remove and clean thoroughly.
- Check the mica or plastic waveguide cover (usually on a side wall) for burn marks or holes.
If the smell is electrical (sharp, chemical) and not from food:
- Do not continue using the microwave.
- Contact a Wolf technician to inspect internal wiring, high-voltage components, and the waveguide cover; replace any damaged parts.
