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 asta12lcc timer flashes 5 times


From the service manual:

Serial forward transfer error during the operation
When the outdoor unit does not receive the signal for 10 consecutive seconds during the operation > Outdoor unit stops.
[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.)

Hi I have a problem with my Fujitsu wall mounted air conditioner ,model AST24RGB-W the outdoor unit fan is running but there is no cold air coming out from the inside unit I put it on high cool to get cold...


I think, your compressor is not working. Check with amphs meter. If less amphs gas leak. Arrest the leak and re charge gas. If tripping with high amphs change capacitor. Still high amps, compressor is defective.

Hi, my fujitsu air-con outdoor machine never start since this summer the indoor machince is working, the model are ASTA18JCC and AOTR18JCC. I set the cool and temp of 20c when outside is about 30c,...


Kelvin, the first step is to turn off the power to the outside unit. The indoor evaporator unit is fed off the outdoor unit. Let it off for 12 - 15 minutes and then turn it back on. This will reset the microprocessor to start up properly. If it does not, then you need to call a service tech to diagnose the problem. They can get phone help from the professionals in NJ - if in the USA.

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

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.
