Question about Fujitsu Heating & Cooling
Green timer light flashes with no heat coming out
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

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.

try turning the power off at the mains ( Isolator switch next to the unit or at the meter box.. Leave off for about 30 minutes as most AC units have a backup memory for when power goes off. Try restarting. If it still goes into a fault code mode ( flashing lights etc) there may have been damage done to the main board due to a power surge.

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.
