I you already tried the power supply reset in the unit ("off" and "on" the supply) may be there something wrong with your thermistor, out of range thermistor can cause error display (flashing LED).Or running the unit with under charge refrigerant is also one of the cause. If the unit operates but no cool at all then that is the cause of error display. Please call a qualified technician to check your unit.

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.

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 Aircon model AST24PBA-W has green Timer light continuously flashing and red Operation light giving 5 flashes. Outside unit fan will not run. What does this code indicate has failed?


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.

Fujitsu asta18lcc has a constantly fast flashing green light and the red light flashes slower 5 times with a small gap between each 5 flashes. Unit wont work at all apart from lights.


The red light (operation) flashing 5 times can be one of four things depending on the green light (timer) but the green light should flash at the same rate as the red light, not faster - either 2,3,5 or 6 times. Anything other than these is abnormal and you will need a tech to diagnose.
Could be a faulty controller board or compressor.

Fujitsu ASTA12LCC operation and timer lights flashing


You need to record how many times each light flashes before it pauses and then repeats. This indicates a specific error that a tech will be able to diagnose and directs them to the components that have failed.

Timer light on fujitsu heat pump flashes not heating


the light flashing indicates there is a problem. you can try reseting the system by turning the power supply off and back on again 30 sec later, if the same thing happens you need to count the number of light flashers and that relates to a fault code

Have you checked for compressor operation? If it is not running you may need to replace the hard start relay/capacitor. If you remove it and get the numbers it is available on ebay for a fair price. eBayeBay
