I have a problem with my 320v power supply. I am getting error A on the PS that translates to phase AC fault. I am running the machine on single phase. The does this off and on. I disconnect the output to the servos from this to check if there was a problem with something feeding back and the problem is still there. Also, I am in southern Arizona and it has been 110 to 120 here every day. This has not been a problem in the past. I also had the power company out here and they said that my voltage looks good and if there was a problem with line frequency then the grid would automatically shut down. This may be true but if there are line capaciators between me and the substation that are acting up then that may be an issue. The guy that came out did not have the equipment to look at the line AC wave anyway. I took the PS out of the machine and put it in the refrigerator. The machine then powered up and ran normal. I am not getting any over temp errors. Haas says a new PS cost $4050 which is about as close to rape robbery and murder as possible. Does anyone know of different sources for replacement PS and other parts. Does anyone know of anybody that could rebuild one of these. There is about $100 worth of parts on a good day in one of these and putting one together from scratch has also crossed my mind.
