I think that your air con is empty from freon. Turn off of the power for 5 minutes. Then turn on and push the emergency button for 10 sec,and see if it's ok. If it isn't i think that for some reason lost all the freon.

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

Fujitsu a/c outdoor model number AOTG12LVC indoor unit economy light flashing continuously, operation light single flash, timer light single flash this sequence repeats


Serial communication error. This means that the indoor unit is not communicating with the outdoor unit usually because the outdoor unit is faulty. You can check the indoor unit by switching it to 'fan' mode and seeing if all functions work normally (fan speed, louvers move as directed). If it responds normally, then it's probably ok so you can turn your attention to the outdoor unit. A common problem with the outdoor controllers is that they are susceptible to bugs, geckos, etc. shorting them out which will mean replacement of the board.

Fujitsu asta24 Lcc timer light flashing all the time even when off no cool air coming thru


A continuous blinking timer light is a "model error" meaning the indoor and outdoor unit is mismatched. If the timer light flashes a number of times, pauses, then repeats, count the number of flashes and then you can work out the error code.

ASTA09JEC Fujitsu model number operation light not on but time light (red/orange) flashing turns on then turns off automatically I have tried the reset button and turned the timer off on the remote


This is a serial signal error which means the outdoor unit is not talking to the indoor unit or vice versa. Most likely the outdoor board is stuffed but you need to count how many times the timer flashes to be absolutely sure which error it is. If you turn power off at the isolator for 5 mins then restart, this can sometimes clear an error caused by power supply fluctuations. If not, you will have to replace one of the boards. Indoor board allow around $200 - $250, outdoor board allow around $300 - $400.

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.

When the indoor unit does not receive the signal for 10 consecutive seconds during the operation >Permanent stop after 30 seconds.
[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.)

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.
