Charge K / Preclean HVPS has failed.

Check the fuse F402 on the AC Drive PWB for an open condition, if not Replace the Charge K /Preclean HVPS. Part# 105E12593
Problem keeps happening time to replace the MCU PWB! Part# 160K95233

Hope This Helps..

Well just in case check for 24vdc at HVPS after that all roads point to MCU PWBA.


Hope this help,
