01 is a comms error as you've no doubt sussed out.

Search for Posistor in the forums, should give you some info which may help depending on your unit model number.

Checked the interconnecting wiring?

If in doubt run a loose cable between the indoor and the outdoor units, I have used extension leads for this in the past.
If it runs on a different cable then you know where the fault is.

:cool:

Either the Diode Bridge or Active Filter module could be faulty- causing the posistor to open circuit. Also, were the outdoor fan motors tested prior to replacing the Main PCB? If not, they could have damaged the new board. Maybe best to contact Fujitsu Tech Support in your local state office when on site.
