We had a similar problem. The timer light would blink 3 times, pause, then blink 3 times again, pause, and so on. The fan was blowing lots of air out, but the air was not cold. The operation light was off.

The technician came and fixed it for free, since it's actually easy to fix. He went to our circuit-breaker box, and cut power (from the box) to the air conditioners for 30 seconds. Then, he restored power - problem fixed!

It's apparently because the air con goes into a "safety" mode when there's a power surge.

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

Ac not cooling

Try turning the main isolator off for 10 minutes to reset the system. If it doesn't clear the error, count how many times the light flashes which will give you the error code.
