    This upload interface is a little clunky. Hopefully the troubleshooting guide uploaded. Hope this helps.

    The 80ton RTAA was never manufactured with a numeric code display .
    Is posting confidential service bulletins a good idea Scott ???

    They are "GENERAL" Service not confidential. The RTAA is out of production and I'm sure Trane would like to help wherever possible.

    I usually jump in one time, and post with as good information as possible, and then leave the thread. I don't have much time to visit here. I want all Trane equipment to work properly, so just providing what I can. I did not download those TSB off the Trane Tech side of the site. He could have downloaded them himself.

    looks like a confidential service bulletin to me. trane wants all of their equipment running well. but they will not release any confidential bulletins...most confidential bulletins anymore do not contain a lot of "special-super-secret" info...

    LOL...way to go guys, been at Trane a very long time, no need to stick my neck out to help. Don't worry about getting information from this Trane guy anmore. Good job

    I remember trying this forum years ago and ended up in all these side battles. I realized I didn't need to be in the middle of it. After all I don't need to be. Guess what I did the 1st time is what I'll do again. Say good bye

    if you want your panties in a wad then fine...the questioning of the confidential service bulletin posting was for your benefit. if you really are a trane technician (still anyway) then you are probably violating the 'never tell any of the super secret info' clauses that you signed.

    i do not care if any service bulletin gets out...i really don't. but i don't post them because i want to keep my job. if you don't or you are not worried then fine...post away.

    ok my advice check your

    check suction and saturated sensor
    check your connectors on the module
    circuit unit charge
    compressor starts unloaded at around 40 percent should jump up to 60 percent when female is energized
    check expansion valve control response
