Fujitsu split system fault codes AST24PBA-W

Red 4 Flashes Green 4 Flashes Power Failure

Off 3 Flashes Reverse Comms Fail In Use

I have one of these units and it has had its fair share of troubles, but great when it is working. My latest issue is the the flap on the indoor unit doesn't open!

This generally works for me. Pull out the isolator outside on the wall or disconnect at the breaker. Leave for a couple of hours. Reconnect and wait 15 minutes. If you are connecting via the isolator you will hear relays clicking and solenoids rattling as the unit goes through a Self Test procedure, then try normal operation.

Most likely a faulty fan motor. You will need a tech to diagnose correctly as this uses a DC motor which has a circuit board inside so has very specific tests. Other possible faults for this code are compressor rotation error, CT abnormal or current trip all of which will need a tech to diagnose.

it means Discharge temp error..did u check it...!?

This link should help.

call in the technicians for a warranty fix

I have same problem like yours to my newly installed Fujitsu multi-split system (the first time use since system installed 1 week ago). I rang the electrician who did the installation; he said it must be the units themselves nothing to do with electricity.

Okay, then I rang Fujitsu and their local service agent. They suggested me to switch off C/B for an hour to reset the units. I followed the instruction but the indoor units still did not respond to remote control...

It simply looks like no power supply to indoor units (they are hard-wired to the outdoor unit). So I used a multi-meter to test the power terminals of indoor units (Danger! If you have no idea about this, don't even try! ): it seemed no power supply even C/B is on. I turned to the isolator which next to the outdoor unit. The isolator was making arcing noise when I switched it on and off. The indoor units suddenly turned on for few minutes then died again.

So I figured out the problem is that crooked isolator. I called the unhappy electrician to replace the isolator. End story....

I hope my experience will help you a little bit.

communications error
try resetting the breaker
this should clear the eprom

I had a similar problem with only fan air then the blinking lights, found out that mice had got into the circuit board and corroded some connections with their urine. I would try the above solution by turning the power off for ten sec first but remember that you have to leave it for a few minutes before you operate remote.
