The indoor unit has the problem and it's the air thermistor. You need to replace it.

My Fujitsu ASTA30JCC has the timer light ( green) flashing twice every 15 seconds and is not cooling


Serial signal error. This means that the outdoor unit is not talking to the indoor unit. There are 5 circuit boards in the outdoor unit and the faulty board could be any one or combination of these. Usually it's the controller board but you will need a tech to diagnose.

Serial signal reverse error. Basically the outdoor unit is not talking to the indoor unit. This is normally due to damage to the outdoor controller PCB and it needs to be replaced.

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.

On my Fujitsu ASTA24JCC wall mounted A/C The operation and timer light flash together x 2 then operation lightred flashes another 3 times after. Then repeats all over again


CT abnormal. This is the current transformer error. It usually means there is a problem with your controller board in the outdoor unit. You will need a tech to check that the compressor and fan motor are OK before ordering a new controller board.

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.
