Installation Guidance

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.
