Inverter Power Drive Unit (PDU) Kit
The Inverter Drive is responsible for converting line voltage into the variable frequency required to spin the compressor. In the XV18 series, the drive electronics are susceptible to thermal fatigue and voltage spikes, leading to a failure where the condenser fan (often DC) operates, but the compressor remains stationary. Replacing the drive assembly restores the necessary electrical commutation and power delivery to the compressor motor.
