ASTA12JCC Inverter system coming up flashing LED error


could be the evaporator capacitor in the evaporator that has gone bad.As long as the motor in the evaporator is free to spin ,more likely the capacitor is defective . Its normally on the logic board soldered in place ,between 1-2.5 uf 450volts (rectangular black looking thing with 2 leads)

I have a Fujitsu inverter split system,(ASTA18LCC) which the power was removed for a while. Now when you start it up on any mode the red operation light is on briefely, then the green timer light flashers...


To work out what the error code ispress the orange start/stop button on the remote controller so unit operationis stopped.
Then press and hold "energy save" and "zone control" buttonsimultaneously for at least five seconds, the error code will be along thelines of En:nn where the "En:" is the error code and the":nn" indicates the indoor unit address if there are multiple indoorunits connected to the one controller. If the upper vertical bar on the capitalE is missing so it looks maybe like a 2 or something don't worry for somereasons they just do that
Some common error codes are:
E0 Communication error between indoor unit and wired remote control, check ifthere is 12VDC between terminal 1 + 3 at remote control and 8-9VDC pulsatingbetween terminal 2 + 3. If DC volts out of Indoor pcb is below about 11.6VDC itwill cause this error, the problem is normally dry capacitors in the 12 VDCpower supply section. This model has two power supply sections on indoor pcb.
E1 Communication error between indoor unit and outdoor unit,
EF Discharge temperature abnormal
Is it helpful?

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.

Fault with 241C Aircon


This happen when you use the inverter for a long time and start getting old and over heat...try to power down the units and keep it for about an hour and then starft them again and try to install a small fan to keep them cool.
