SOURCE: We have a Fujitsu ASY-40UIM3
There are two things that can cause this.
1. Is the high voltage line energized. Is the power coming to the unit, make sure the disconnect is not tripped or manually shut off or pulled out and reversed. Check that the circuit breaker is not tripped.
2. Was some wiring error made with the control wiring that connects the outside condenser to the inside evaporator? Is there power here? Is the transformer working?
I am assuming that the unit was properly filled with gas.

the manual said that error code is cause of discharged thermistor..
-The detection value of the discharge thermistor is either open or shorted > Compressor, outdoor fan: OFF (automatically
releases when the value is returned to normal)
-Check the thermistor resistance values (refer to thermistor value chart)
-controller pcb defective...
