If you can pick up the 2006/2007 Air Conditioning catalogue from NRS (Climate Centre) you will find all the fault codes for Fujitsu, Panasonic and others in the back pages.

Re: 01 fault on fujitsu
o1 error is comms error between indoor and outdoor unit.
disconnect the serial comms wir at the outdoor unit, making sure its safe and out of the way when you turn it back on.
Check the voltage on the #3 terminal (still wired up to the indoor) check the voltage at the wire you removed (which is connected to the outdoor pcb)
you should get 90-120v ac from either, whatever one has no/low voltage is dead.
might be the control board itself, or a board that supplies power the the control board.
My bet is if you had a power surge, possibly more that just the indoor filter PCB and outdoor inveter PCB would be blown too.
I.e there's a outdoor filter pCB and a indoor control PCB.
What does the indoor unit do, is there display on the controller, does the indoor fan turn on when on fan mode?
edit: What does the outdoor unit do, when you first turn it on via the isolator does the power relay click in, do you hear the tx valve hammer open/closed for 5 seconds?Last edited by paul_h; 07-10-2007 at 01:51 PM.
