Fujitsu k9710995644 Controller Pcb Hybrid

Product Description

The FUJITSU k9710995644 is a hybrid controller printed circuit board (PCB) designed for use in compatible Fujitsu mini-split and heat pump systems. The controller PCB serves as the primary logic and switching board, managing system operation, signal processing, and component coordination. This is an OEM-specification replacement part intended for installation by licensed HVAC technicians experienced with ductless and hybrid heat pump systems. Replacing a failed control board restores normal system function and protects connected components from erratic operation.

This controller PCB is designed for use in Fujitsu hybrid heat pump systems. It is suited for residential applications where the original board has failed due to electrical fault, surge damage, or age-related component degradation. Compatible model application is limited to indoor or outdoor unit configurations as specified by Fujitsu service documentation. Installation is typically performed during a scheduled service call or warranty repair.

Key Features

• OEM-specification hybrid controller PCB for Fujitsu systems
• Manages logic, switching, and signal coordination within the unit
• Direct replacement for failed or damaged control boards in compatible models
• Sold individually as a single unit replacement component

Compatibility

Compatible with Fujitsu model RIDH18-30AXCJ. Verify model and serial number against Fujitsu service documentation before ordering to confirm fitment.

Installation Notes

Controller PCB replacement should be performed by a licensed HVAC technician familiar with mini-split and hybrid heat pump electrical systems. Disconnect and lock out all power to the unit before removing any panels or handling the board. Follow NEC guidelines when working with low-voltage control wiring and line-voltage connections. Take appropriate electrostatic discharge (ESD) precautions when handling the PCB to prevent damage to sensitive components.
