Sounds like your compressor is seized or a start fault. If the unit is under five years old it should be under warranty. Call Fujitsu warranty out to have a look at it for you.
Contact details as follows

Sorry but either way I think your going to need a part there is very little that I can do unless your in WA.

Hope this helps

SOURCE: replace remote control unit model ar-fb2

If your remote control have display but cannot transmit signal to the unit. Confirm first if the remote is really the problem, using your camera or cellphone camera as your eyes point the remote transmitter to your camera and "on" the remote. You should see light emits in your remote control, if no emitted light then the remote control is defective. But if there is a light the defect is in the unit receiver.

Check also if there is a reset or rst button in your remote control and reset it and try.

Check also if there are error codes in the unit, reset the unit by disconnecting the power supply in the unit for 10 sec. and "on" again and try.

The unit can be operate without remote control, use the manual button located in the unit.

If the remote control have no display replacement of remote is recommended.

What does 3 green led flashes in sequence, operation led off mean on Fujitsu ASTA09LCC aircond


This means a "Serial reverse transfer error during the operation"
Diagnosis:
When the indoor unit does not receive the signal for 10 consecutive seconds during the operation
>Permanent stop after 30seconds.
[Diagnosis Point]
Check the indoor /outdoor cable connection (in order). If the cable wiring is not abnormal, measure the voltage of the outdoor
unit terminals and diagnose the defective location.
(Refer to the after mentioned [Serial Signal Diagnosis] for the voltage measuring method and diagnosis method.)

This is generally caused by a faulty controller board in the outdoor unit. Often they are shorted out by geckos or bugs but sometimes a power surge.

I have a fujitsu air con which is flashing 3 times on the timer. It runs for 10 seconds and then shuts down and then flashes 3 times. Model is a AOTR09LCC


Serial signal (reverse) error, during operation.
Try turning power off at isolator for ten minutes and then switch back on. If error code persists, you will probably need a new controller PCB in the outdoor unit.

HOW DO I FIX FUJITSU AOU24CL1 SERIAL SIGNAL (REVERSE) ERROR, AT OPERATION STARTUP


Outdoor controller circuit board sounds faulty. This error means that the indoor and outdoor units cannot communicate. Replace the outdoor controller in this case. Check if there are more than one outdoor PCB as others can be damaged as well.

Repeating flash


Serial signal (reverse) error, at operation start up. Usually a faulty outdoor controller board but this one has about six PCB'S in the outdoor unit so your going to need a tech to look at it.

Eee code displayed


To work out what the error code is press the orange start/stop button on the remote controller so unit operation is stopped.
Then press and hold "energy save" and "zone control" button simultaneously for at least five seconds, the error code will be along the lines of En:nn where the "En:" is the error code and the ":nn" indicates the indopor unit address if there are multiple indoor units connected to the one controller. If the upper vertical bar on the capital E is missing so it looks maybe like a 2 or something don't worry for some reasons they just do that
Some common error codes are:
E0 Communication error between indoor unit and wired remote control, check if there is 12VDC between terminal 1 + 3 at remote control and 8-9VDC pulsating between terminal 2 + 3. If DC volts out of Indoor pcb is below about 11.6VDC it will cause this error, the problem is normally dry capacitors in the 12 VDC power 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

Split unit, I get heat but no cold


I have run into this with the LG brand systems. try shutting power off to the outdoor unit to reset all units. If problem persists, it could have to do with a charge level of refrigerant (freon) or possibly a failed control board.

System will not start up.


This is a signal fault between the indoor and outdoor first make sure the dip switches are set start with the unit closest to the condensor set as unit 1 then next unit as 2 and so on the dip switches are inside the indoor unit on the pc board if you check the manual it will tell you which swithes to set, if this wasnt done when the units where installed they would have never worked i would also check the signal wiring between the wallmount and the splitter box / bc box and make sure there isnt a loose connection when you have ruled this out id say more than likely it is a faulty indoor board on the wallmounted unt
