My Fujistu AST9LSACW split system air-conditioner wont blow cool air. the outside unit AOT9LSAC doesnt seem to be working at all. The power light stays on but the timer light flashed about 15-20 times a minute. please help...

There are two things you can check outside before calling a service technician. The first is the breaker to the outside unit. There is a breaker or disconnect near the unit. If there is nothing wrong with the electrical supply, check the refrigerant level. If the level is low, the pressure switch will cut off power to the compressor to protect it from damage. DO NOT try to recharge the compressor yourself.
