Looks like you said it, the outdoor unit is not working. Check for power to the outdoor unit or try cutting power to it, then after a minute restore power in attempt to reset it.

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.)

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.

Error code timer light blinks twice


Depending on the model, this usually means "Serial signal (reverse) error at start up" which means that the indoor unit is not receiving a response from the outdoor unit when it tries to "talk" to it. It can be several causes but In my experience, it is usually the outdoor controller board. Again, depending on the model, there can be several boards in the outdoor unit any or all of which could be causing the fault as well as a faulty fan motor or compressor. The bottom line is that you are going to need a tech to take a look at it to diagnose properly.

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.
