[@user-pb1dz6bd4s]

i think inverter pcb bcoz bcos fan pcb power supply from inveter pcb if im correct .usually i change both pcb

[@boulmo9167]

Change the whole pcb and u good

[@ronaldoxotza9145]

You Must change the Inverter PCB because the middle phase of the noice filter whaits confirmation from the inverter pcb to close the cycle.

sir, how much is the normal refrigerant pressure for the ac vrv ?

[@davecoolaircon]

Is it the(faulty) Filter Pcb output voltage to Inverter Pcb is incomplete, then causing Inverter Pcb fail to work and no DC voltage output to DC fan Pcb right ?
