Genuine Fujitsu Outdoor Inverter PCB 9709904626 – AOTG45LATL

This is the factory original Fujitsu outdoor inverter printed circuit board, part number 9709904626, used in AOTG45LATL outdoor units. The inverter PCB controls compressor speed and outdoor fan operation and manages the DC bus, so when it fails the symptoms are usually dramatic: the outdoor unit will not start, the compressor trips shortly after starting, the fan does not run, or the system reports a communication or inverter error and shuts down.

Typical symptoms of a failed outdoor inverter PCB

• Indoor unit runs but the outdoor unit never starts
• Compressor starts then trips within seconds or minutes
• Outdoor fan motor does not operate
• Inverter, IPM or communication error codes displayed
• Visible damage on the board: burnt tracks, bulged capacitors, blown fuse, scorching around the power module

Before you order

Confirm the outdoor model and serial number from the data plate and check the part number on the existing board. Inverter boards commonly fail as a consequence of another fault rather than on their own – a seized or shorted compressor, a blocked condenser causing sustained high pressure, a failed outdoor fan motor, or storm and surge damage. If the underlying cause is not corrected, the replacement board will fail too. We recommend having the fault properly diagnosed before purchase, and we are happy to review error codes and photos with you.
