Hi guys
Today I came on site and found DAIKIN VRV 2 with main circuit breaker off - D63 A . Checked condensing unit and diagnose inverter board faulty . Taken another the same board from same model and fitted . Changed main circuit breaker C 60 A and turned unit ON . Immediate switched unit off because varistor on main PCB board F2S start burning ... see the picture 9054
I am very desperate what going on .... :( It looks like L3 Phase crossing with neutral somewhere but i am not sure . Please if anyone knows what could be problem please let me know or please send me some service manuals on my email Thank You very much .
