    Angry Mitsubishi Heavy Industries



    Has anyone had any dealings with model number FDCA450HKXRE4A?
    One of the two compressors has no voltage to it although the contactor is pulled in. I have 415v both sides of the contractor. I have replaced the inverter board, but still the same. I'm thinking the power transistor maybe?
    They are a pig to work on!!

    I can't remember these exactly, apart from the inverter board, does it also have a power board?
