SOURCE: i have a Fujitsu ASTA24LCC

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.

SOURCE: Operation and timer light flash

Please cancel your timer setting by reset the power. And also remove battery from your remote and reset it. Now start your unit.

SOURCE: 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

LG aircon operation flashes blinking light 8 times and then shifts to timer light flashes blinking light 4 times


Sounds like a 48 code. (There is no 84 to my knowledge).
Outdoor unit coil outlet (liquid line) thermistor has disconnected or has shorted out.

call a LICENSED hvac repairman

Heat pump won't start, red light flashing


I do warranty work for Fujitsu ACs. You need to be more specific with the "Flashing" How many flashes of both the timer, and operation light are there? These relate to problems/faults. Take note next time and post it back here.
