    RTTA135 Blew compressor terminals

    I was asked to look at this chiller and give our recommended steps to get this machine back on line. The customer advises me Ckt A has had this happen twice and Ckt B has done this once before. He also explains history with coils being dirty and relief valves leaking. So with these things in mine does anyone have any input with experience to root cause the compressor terminals blowing and gas leaking out? They are R series screws doing comfort cooling at a plant. Trane has compressor terminal repair parts in stock... Thanks in advance

I was given this information over the phone and asked to quote so i did today. I have alot of educated theorys but just curious if any body else had any experience with this problem. I'll update if i get the job. Thanks ga.snowman

    You would be wise to put eyes on the comp terminals. You may have to crimp on new studs. Not impossible, but a little time consuming and will need a special crimp tool.
