How to Fix / Troubleshooting

Safety first: Turn off the circuit breaker and unplug the microwave before any inspection. Internal fuses are near high-voltage components.

Check outlet: Plug another device into the same outlet to confirm power is present.
Inspect cord: Examine the power cord for visible damage. Replace if necessary.
Internal fuse (advanced): Remove the outer cover to access the internal line fuse. If blown, investigate the cause (e.g., shorted component) before replacing.
Thermal fuse: Check cavity or transformer thermal fuses for continuity. Replace any open fuses with exact Miele-specified parts.
Professional help: If fuses blow again after replacement, a deeper fault exists and should be diagnosed by a technician.

Microwave display is blank and unit appears completely dead; interior light does not turn on when door opens.
