    I had a produce line down the other day. Couldnt figure out why this one unit wasnt coming on. I checked the little bitty fuse in the rack controller and sure enough ... it was blown.

    So I just paid a visit to another rack controller and robbed Peter to pay Paul.

    Just curious why it would do that....

    Control circuit is what those fuses are tied to. Check for shorts and loose wires on your control circuit side of things...i.e. sport valve coils, sorit valve coils...anything on that relay board on that individual relay is suspect.....Eric
    If you cant find the time to do it right the first time, then you wont find the time the second time around....

    Talking about an R.O point? Most of the time it's the contactor coil, if not--- the compressor board. Wiring burns up sometimes. Depends what you're controlling.

    No. What do I do? Tie a shunt meter inline with the load on that circuit?
