Yea I did all that thanks. Yea i got the process of elimination part. It just suck when you spend over 500K or more with a vendor and when you ask for a little tech support you don't get it. Anyway. The OSCD logic board was bad and chiller is running good now. But I still don't know if all 6 LEDs are to be lit on the filter igbt cause only 5 r. No faults chillers good. Thanks
i work for said vendor and tech support is difficult for me to get too...once i get it, it is quite good.
