    new compressor or not

    i have a 5 ton trane hp (i believe XL1000). bad compressor - shorted to ground. i've never replaced just a compressor on a unit. how do i know the reversing valve is working (unit is holding good pressure - appx 150). Next question. On some old units, you can't find the same compressor i was told, so does it really matter what type of compressor as long as it is the same BTU, volts, and size? I don't want to replace compressor and unit not work?
    I was told at the supply house that on these units, changing the condensors only have been burning compressors up within a year. so it seems the best solution might be to replace compressor, thanks for any help

    Sound to me like folks aren't clean up before installing a new Comp. And /or pulling a vacume with a micron gauge to 500 microns.

    if it is a bad burnout i would change the valve with the compressor.
    usually ill get some of the oil out if the comp. & test for acid.
    being a valve that shifts with pressure differential you need an operating
    pump to check how it shifts. 50/50 chance it will work.

    You can't, but surely one of the moderators will.
