Fujitsu air con fault (new system)

Hi, we have installed this system from new & when trying to run for the first time, the outdoor unit does not run & the indoor green light flashes 3 times at every 10 seconds (approx) the supplier thinks it is the o.u pcb ! would like to know what the Fujitsu warranty policy is ? do we start fitting boards at our expense or should this be down to our suppliers?...thanks..steve

Steve, first look at the manual if really it is stated in there that the three blinks indicates an o.u. pcb. second, do you install them yourselves?. im not sure regarding warranty if you install them. normally there should be a qualified installer to install it to cover warranty. again if you install them yourself, double check the wires that goes to the outside unit. make sure each wire goes to its corresponding location. any mis-wiring would may also indicate a 3 blink alarm. if its covered in warranty. they should shoulder the expense if it needs board replacement. i hope i was able to solve your problem.. tnx

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.)

I came across a brand new Fujitsu Split System out door unit (AOTR24JCC), so Im look for the indoor unit (ASTA24JCC) Where can I find one? Thanks


Model is over 5 years old so unlikely to get a new one. However, the outdoor units fail while the indoor is good so check eBay or your local installer.

My outside toshiba split system is leaking a lot of water


If the unit is on heat mode, the outside unit is the "cold" end... Sometimes if the ambient air temperature is very cold ( Under 5 degrees C), the outdoor unit can start to ice up. If it ices up too much, the air con will automatically go on to a defrost cycle where the outdoor unit will heat up and melt the ice. Water is then drained out the bottom.. its the opposite of what happens in the summer when the indoor unit has water running out of the drain hose. Especially on humid days..

Fujitsu inverter air cond. Just stopped working properly. Model outdoor AOT30PMAL indoor unit AST30PBA-W. Code oper. Red led flashes fast continously green led (timer) repeats 13 slow flashes. After power...


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.

Water dripping from air con use


If the unit is mounted on an outside wall check the condensate drain that comes out with the line-set to the outdoor unit. If the pipping goes up into the attic than you have a small condensate pump that may have failed. The float in the pump may have stuck in the down position not allowing the pump to come on.

Have just installed a Fujitsu Asta 24lC air con heat pump problem


Hi Shannon,
I would pursue your fight with Fujitsu, normally their units are reliable:(
It could be a really simple problem or a really complex one ranging from many componenets. A air conditioner has many more components that people may think. Keep fighting to get the unit repaired will it is still under warranty, after that Fujitsu wont want to know you. It could also be a wiring and refrigerant fault. Call Fujitsu out again.
I take the time to answer your question, so please rate me.
Thankyou Mat

Will Not Heat


On the outdoor unit the fan should not be running, on the indoor unit the fan should be running. If you then check the outdoor unit with fan not running, you should be able to hear clearly that the compressor is actually working. If this is all correct, it is possible that your fourway reverse valve is seeping and needs to be replaced.

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

Fujitsu AOT30PMAL inverter outdoor unit not working


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.

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
