Fujitsu Triple Split.

[bucko]

Hi I have a fujitsu triple split indoor units run and there are no flashing lights to indicate a fault,just the operation light is lit,however the outdoor unit will not run in either heat or cool mode any ideas?

Thank you in advance for any help.

Maybe you have a communication error if you have your indoor units wiring running through a switch or isolator check them for continuity or chocky block 2 and 3

Hi I have checked continuity and there is no problem there,i have also changed the main outdoor pcb with no luck.

Try taking 1 indoor out of the daisychain at a time to see if an indoor pcb is at fault start with the first 1 on the comms cable.

On the outdoor board is there a light flashing in a sequence if so then it is a fault code give fujitsu a ring and they will tell you what it is other than that just go round and check all the wiring and fuses on the indoors and just to state the obvious all of your switches to the indoors were on before you turned the outdoor on.
