    Model number would help. Is this a 2 compressor or 3 compressor unit? Are A&B on the same circuit or separate circuits?

    I thought in the menu there was an option to disable or take a circuit or single compressor out of service.

    We're running a 300T until with just compressor C, since circuit 1 has too many leaks in impossible to fix locations, so its' been abandoned. The building only actually need 100-120 Tons anyway.

    Yes, in the service test menu.

    I will cycle through pumpdown cicuits, then EXV test and then lockout circuit A, B,.

    Idividual compressors on a tandem (twinned ? ) configuration can be isolated by pulling the control wire.

    Is one bad ?

    If it's a burnout I wouldnt recomend running it.

    I dont like to isolate individual compressors on a tandem assembly after compressor failure.

    Large/small, fat/thin, short/tall, smart/stupid, ugly/pretty, normal/weird: all depends on who you're standing next to at the moment.

    That's a fair question concerning the idiosyncracies of the American English language. Not knowing you personally, I can't comment on how it actually applies in your case......
