    Indigo Manitowoc

    Have a ID right as it goes in harvest I hear the hot gas open but the cond fan does not shut off. Now I ran manual a couple of time back and forth only 1 time did the fan cycle off. Also as it goes into harvest the txv flooding alarm show.
    It's makes ice beautiful when it get to harvest also so charge is not a worry I think.
    I am thinking the controller failed. I thought I heard the main controller relay chatter also.

    It just seems that when it call for harvest the hot gas and fan do not cycle correctly leading to a moan controller fault

    Will that prevent unit for going into harvest? And I do have it scheduled to Clean in the morning when the place is not busy

    If cleaning does not help, I would give Manitowoc tech support a call on Thursday.

    They may have a better way to determine if the controller is actually on its last legs.

    If the compressor is energized the fan has the ability to run even in harvest. Dirty condenser or faulty fan cycling switch are very common.
