Fujitsu k9707125054 Ipm Pcb Module RAC24

Product Description

The Fujitsu k9707125054 is an Intelligent Power Module (IPM) printed circuit board designed for use in Fujitsu mini-split and ductless air conditioning systems. This PCB serves as the inverter drive board, controlling the variable-speed compressor output in RAC24-series units. It manages the high-frequency switching signals that allow the system to modulate compressor speed for precise capacity control. Installation is performed by licensed HVAC technicians as part of a compressor drive or control board replacement procedure.

This IPM PCB is specific to the RAC24 platform within the Fujitsu residential and light-commercial ductless lineup. It is commonly replaced during inverter drive failures, where symptoms include unit lockout fault codes, compressor not starting, or erratic capacity output. The board is an OEM-sourced component intended to restore original factory inverter performance in affected systems.

Key Features

• Intelligent Power Module design for variable-speed inverter compressor control
• OEM replacement board matched to RAC24-series system specifications
• Manages high-frequency switching for compressor modulation
• Direct drop-in replacement to restore factory inverter drive function

Compatibility

Designed as an OEM-style replacement IPM drive board for Fujitsu RAC24-series ductless mini-split systems. Also referenced under part number 9707125054.

Installation Notes

Installation of this IPM PCB should be performed by a licensed HVAC technician familiar with inverter-driven ductless systems. Disconnect all power to the outdoor unit at the disconnect and verify zero voltage before handling any PCB components, as residual DC bus voltage in inverter circuits can remain hazardous after shutdown. Use appropriate ESD precautions when handling the board. Follow all applicable local electrical codes and the manufacturer service documentation during reinstallation.
