You may need to open the louver and hold down the Manual/Auto button for 10 seconds to see if you can reset the machine. Additionally, unplug the unit for 30 seconds or so and then plug back in.

Check that the gas is not leaking, that would be the most likely cause.

Check your filters. Manual says they need to be cleaned every two weeks under normal operation (and in my case more often during renovations). It seems it may not take much to limit air flow enough for the indoor unit to trip out. Hope this helps.

FUJITSU Indoor Inverter ASTA09LCC/ASTA12LCC airconditioning - not cooling


If the operation button is flashing 8 times, the timer light should also flash 4 times in each sequence. This indicates a failure of the PFC circuit in the outdoor unit which basically means a faulty outdoor board and will have to be replaced.
If the operation light is flashing 8 times by itself, the indoor controller board may have a fault. You can normally test this by putting the mode on the remote to 'Fan' and checking that the controls otherwise work normally - louvers work as directed and fan speed changes correctly when selected on the remote.
Most likely the fault lies in the outdoor board but you should contact a tech to diagnose correctly.

Heater not working


Model ASTA24LCC found that the problem was the valve inside the out door unit that reverses the flow of the R410A, the service fellow gave it a bit of a tap and restarted unit to find that it would work, hope this help some one else out there with a similar problem, the inside unit operation and timer light would flash together twice then just the operation light would flash five times, was told by Fujitsu that this was the code for refrigerant problem.
