    trying to jump out an XM board on heat pump

    Carrier wshp
    Model# 50RVC036LCC60130
    Serial# 3907V39197
    460v 3 ph

    keeps going into "fault retry"...slow flash intermittently

    Flushed out system, virgin r22 and same thing

    supply V - 464v average

    control V - 25v........So I know its not a UNDER/OVER voltage issue

    how would I jump out this board to get it running til i get a new xm board? OR CAN I???
