    so your lead chiller tech is trying to ruin 2 machines? this newly rebuilt chiller obviously has a different problem than the other chiller, so what's the difference between them? it doesn't sound like you had these kinds of problems before the rebuild.

    Could the load on the second chiller be drastically different than the first? Hate to ask dumb questions but I have been screwed by other people telling me, "Of course the strainer is clean I cleaned it myself" or finding startup strainers in five year old jobs.

    Well the oil scavenger line from the evaporator is open about 1/8-1/4, I know that for sure.


    I also know that the vent line solenoid is NO.


    As far as I know before the overhaul the chiller had oil return problems, but I'm not sure what else was behind the decision to overhaul. I know that it is a bid job. We do not have a contract with the customer.

    I agree that there are a lot of unknowns. I was hoping there might be an easy answer or something that would ease my mind about whether what I'll call the mechanical overhaul part was done correctly.

    As far as water temperatures and flow, I think that it is possible that they might have something to do with the problem considering the cold oil temperatures and oil return problems that existed before the overhaul.

    Regarding the open forum, I apologize for the depth that this is getting into. For what it is worth I am an apprentice with Trane factory service and sometimes I don't feel like I get the best answers from some of the other technicians. Therefore I've come here seeking more understanding...but I have to get my post count up to post in the Pro Forums, right?

    To the OP why has the lead tech not been on the phone with lacross since the issue started or have they?

    I am not sure if he has talked with tech support or not. I will follow up if I hear anything. As of right now it is all quiet. Not that that means it is fixed.

    So you're an apprentice for the service agency that's a part of the same company that designed and manufactured the machine, with probably more than a handful of "seasoned" techs in your office, and you have to come to an open internet service forum to try and get answers as to why the chiller in question has a problem? Comment deleted for lack of civility Oddly enough, I know of another manufacturer with that same issue........

    I think someone's going to end up getting called into the office for a little 'chat'.

    some techs will tell you to keep your mouth shut and your ears open....good advice.

    i have seen some techs say that because they can't answer any questions because they don't know the answer and they are grasping at straws.

    which camp are you in? you probably will never know. i hope that there is at least someone in your organization that will act like a true teacher....find them and ask lots of questions, but do your homework and be prepared to answer their questions when they are teaching you.
