    Carrier 30gxn discharge superheat?

    Ive got a Carrier chiller that Im trying to troubleshoot but cannot find anywhere in IOM that tells what a typical discharge superheat is for this unit. From what I can tell the Main Processor Board uses that has info to open and close EXV.

    Does your machine have a liquid level sensor? It would be on top of cooler near compressor.
