    cvhe overcurrent problem?

    can a bad oil pump cause the chiller to go into an overcurrent alarm, if so how and why .? if the pump was bad how would it even attempt to start without the proper diff. ?

    I personally wouldn't think so, but do you have anymore info on the job? Type of starter, what control panel, etc? Maybe a compound problem? Let's hear the details 😃

    No! Should never start because of low or no oil diff!

    Wait, let me start again! If the oil gallies were stopped up with aluminum, it could show normal or high oil diff. This would be a spun bearing. Your chiller module ought to have picked this up. Unless it was reset multiple times. "Hey it went out on surge again! Lets reset it!" You never know what you're running into.
