It sounds like your inverter is at fault. You will need an inverter tester ( most good service techs will have one ) to prove that the output to the compressor is correct. If the inverter is okay then it will be the compressor at fault with a location error or it is simply seized. A common fault that caused this was the eev remained closed (coil failure ) and caused the compressor to over heat.

SOURCE: Fujitsu General ASHA09LAC Multi Inverter

Your split system is an inverter model. In it the compressor is powered not simply from the mains thru a relay but from a special and very complex set of converters: a rectifier to convert the incoming AC current to DC and then uses pulse-width modulation of the DC current within an inverter to produce AC current of a desired frequency to power the compressor.
In your case the unit that provided the final AC current to the compressor has failed. The fact this happened a few days after you have started using it is a clear indication of manufacturing defect - some of the electronic components used in that inverter were of a low quality and they haven't been able to cope with the stresses so they failed.
This is something that only the dealer (and its repair crew) can solve and it's covered by the warranty - time to call them. And in the mean time disconnect the unit from the mains.

FUJITSU Inverter wall mounted split air conditioner Model : AST12LSBCW not working, flashing lights


This is a "PFC circuit abnormal" in the outdoor unit meaning that the outdoor controller board is faulty. Try turning the machine off at the isolator switch for 10 mins, then back on to see if the error resets. If not you will need a new controller PCB.

What does error message mean on Fujitsu inverter aircon model ASTA30LCC. red operation light flashes on 5 times with green timer light flashing on twice. Can someone please tell me what the fault is?


This is an "Outdoor unit control error" - specifically, a "Current trip error". There is a problem with one or more of the outdoor boards and you will need a tech to diagnose.

MY FIJITSU inverter is not working correctly, the timer light is flashing continuously and the timer lights flashes 5 times can anyone help pleawe


fujitsu is a good brand.
try one of these two things:

Turn the unit off then on again. After that press test button on remote control (rear side) and look how many times now operation and timer LED flashes. Note that. Then press MANUAL/AUTO button on indoor unit until you hear 3 beeps from buzzer. That will erase error memory.
Switch off and than on unit and see if indication repeat or it is gone. If it is gone, keep using your unit.
If it is repeated post your notes here.

OR+++++++++++++++++++++FOR OTHER MODELS

5 x Operation flash and a constant Timer flash indicates an outdoor unit control error. With this code flashing on the indoor unit, you need to point the remote at the unit and push the test run button. The flash pattern will change to a continuously flashing Operation light and a number of flashes of the timer light which gives more detail on what the error is.

To get the unit to try to restart you need to push and hold the manual/auto button on the indoor unit for a few seconds then reset the mains power supply but leave it off for a minute or so for the unit to power down completely. If you are going to try this make sure you make a note of any error codes first if you have to get someone out to look at it, it will help them a lot.

I have a Fujitsu inverter split system,(ASTA18LCC) which the power was removed for a while. Now when you start it up on any mode the red operation light is on briefely, then the green timer light flashers...


To work out what the error code ispress the orange start/stop button on the remote controller so unit operationis stopped.
Then press and hold "energy save" and "zone control" buttonsimultaneously for at least five seconds, the error code will be along thelines of En:nn where the "En:" is the error code and the":nn" indicates the indoor unit address if there are multiple indoorunits connected to the one controller. If the upper vertical bar on the capitalE is missing so it looks maybe like a 2 or something don't worry for somereasons they just do that
Some common error codes are:
E0 Communication error between indoor unit and wired remote control, check ifthere is 12VDC between terminal 1 + 3 at remote control and 8-9VDC pulsatingbetween terminal 2 + 3. If DC volts out of Indoor pcb is below about 11.6VDC itwill cause this error, the problem is normally dry capacitors in the 12 VDCpower supply section. This model has two power supply sections on indoor pcb.
E1 Communication error between indoor unit and outdoor unit,
EF Discharge temperature abnormal
Is it helpful?
