SOURCE: Fujitsu Heat Pump - problems

I had the same problem. The heater did not work in heating mode. However it was OK in air-conditioning mode. The operation light and the timer light blink twice and then the operation light blinks for 5 times followed by few seconds non blinking, then the cycle repeats again. I have read on the internet that you better unplug the power cord and then plug it again so that the heater re-sets itself. My only problem was that my heater is directly plugged to the power with no visible plug. So I went to the main distribution board and put off the power for about 20 seconds for the whole home. HOORAY!! The heater worked after that.

SOURCE: The timer light flashes twice about every 15 seconds

This may mean that the filters may need to be cleaned. According to service manual the unit has a "Serial reverse transfer
error at start up operation". Call fujitsu for service if the fault cannot be rectified.

Below is an extract straight from the fujitsu service manual:

Compressor location error
The compressor speed does not synchronze with the control signal. (Including start up failure of the compressor).
> permanent stop.
[Diagnosis Point]
Check if 2-way valve or 3-way valve is left open.
Check the compressor (Winding resistance value, loose lead wire).
Refrigeration cycle defective (Refer to after mentioned "refrigerant cycle diagnosis")

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.

Timer light flashes twice on my asta09lcc but it wont work


If operation light is normal and timer light flashes twice, the error is:
Serial signal (reverse) error, at operation start up
Most likely a faulty outdoor controller PCB. Around $250 for new board plus labour.

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.
