    Carrier 30RBA160 not staging up

    Hi, need some help here, since Carrier has washed their hands of this problem, I have a 30RB160, 2005, I need to change 1 compressor [again] and need to disable the "A" circuit to work on it, when I do this, "B" circuit will not stage up and maintain water temp, only 1 "B" compressor comes on with Hot Gas, and just runs forever, no other compressor{B circuit} will stage up, I've done this in the past and never had a problem with "B" cuircuit staging up and controling water temp. I've tried to stage on Circuit "A" just to see if I can do that, and it works perfectly. Carrier has asked me to do several things to it and still doesn't work, [so many, I can't name them here] I've had to replace so much on this machine, I wish I could trade it for something else. The last response I got from Carrier was,"We don't know why it's doing this, Sorry" Any help would be greatly appreciated. Lonnie

    Are there any override modes on preventing it from loading up? Has any software been upgraded? Power problems ? Why are your compressors failing , contagious welded?

    It takes three people to do anything around here. Two do the work, one explains to the crowd of people who showed up when they seen smoke and flames.

    Maybe you could explain to me just what a override mode is, I'm not clear on this since I didn't see any override modes,

    Thanks for the replies. No override modes. Don't know reason for failures, but thinking ,like was suggested, need upgraded version and maybe will solve problems, not all the same problem with compressors, 3 were vibrating so bad, it broke the discharge line twice, 2 were shorted, the rest just locked up. Will see if Carrier wan't to talk to me to upgrade my software. Thanks. Lonnie
