Fujitsu Split AC errors

[parlox1]

hi.

I have a fujitsu split AC. Indoor is an ASYA24LCC & the outdoor is an AOYR24LCL.

The problem is that the green timer light is showing a fault. Firstly it flashes twice then after a few minutes flashes 3 times. The operation light is off whilst this happens.
According to the info I do have it says the fault is reverse comms fail on start up and reverse comms fail in use.
I have no more info on how to remedy this fault.
I have checked the wiring and all is as it should be. Is it simply a fault with the indoor or outdoor PCB? or is there more to it?
Btw,I have no manuals on these units.


Any help much appreciated

Make sure the outdoor unit has 240v AC supply to the PCB and out, into the inverter and out 320V DC

Hello PW,

Does your condensor fan or compressor run at all? Got the same unit and my problem is condensor fan only runs for a few seconds ...no signs of life from compressor either in cool/heat...juice to it and managed to blow a board connected to comp! Would be interested to know if you've had similar problems???

Thanks,
