Installation Guidance
Disconnect power before service. Internal microwave components can retain a lethal electrical charge after unplugging. Internal repairs and work involving the door, shielding, or interlocks require a qualified microwave service technician. Follow the manufacturer’s model-specific procedure. Never bypass safety interlocks or operate with damaged doors, shielding, or covers. The technician must complete the required safety checks before returning the microwave to service.

- Unplug the microwave. Internal high-voltage components can retain a lethal charge after power is removed. Follow the service manual, discharge the high-voltage capacitor using approved procedures when cabinet access is required, document wiring and orientation, and verify all shields, interlocks, and covers before operation. Qualified microwave service is strongly recommended.
