    Carrier Gas pack Model number

    Hi warm people..

    I have a 20 year old carrier combo gas pack on my roof but cant seem to find the model number due to all the info being sun faded here in HOT Tucson. I do have a couple part numbers of two control boards and pictures to boot.

    Anyone out there have knowledge of old carrier unit if I give you a part number off a board and some pictures, CARRIER WON'T TALK TO ME AND WHEN I HAD A DEALER CALL, THE GAVE THEN 200 POSSIBLE PART NUMBERS.

    Or can someone tell me where to find a model or serial number on this unit

    Thanks a MILLION in advance

    Cold person for a week in Tucson...

    Behind a panel on the unit, there's another silver panel covering the electrical control box. Carrier puts another nameplate there. Hopefully that one isn't oxidized or faded away.

    eletrical control box?

    THANK YOU!!!!!!!!!!!!!!!!!!!

    When you speak of the electrical control box are you speaking of the compartment with the control boards? See picture attached

    Thanks

    Yes. Was there not another silver panel in front of the control box?

    You might have to call a tech in to take a look at it. As the dealer said, there's hundreds of possibilities.

    a matter of effort

    lack of a model number does not mean your out of luck, as someone who used to work a parts counter for a carrier distributor i know a thing or two...first of all part numbers can help by narrowing down potential models as carrier distributors have a program to cross refrence those numbers to the various units they were used on (providing the unit isn't too old)...secondly, if you know the age of a unit the results can be further narrowed by what models were manufactured during that period. in the end it is still going to be a guess but narrowing down to a dozen or so candidates is possible. if you post a part number for the control board and the compressor (if readable) and guestimate the age i'll see if i can call a few contacts to narrow down your possibilities a bit

    just hit me the serial number you provided 3190007255 is probably 3190 G 07255 which would be a 1990 model unit. does that sound right?

    a 48n_t model does fit the appearance and time of manufacture from what i see. that information along with knowing how many burners has norrowed down the information to which i have access to the following possibilities...

    48nht030
    48nmt036
    48nht036
    48nmt042
    48nht042
    48nlt048
    48nlt060

    these models do have the stacked circuit boards as show in your picture so if your unit is in fact a 48n model theres a good chance one of the above will apply

    030 = 2.5 ton / 036 = 3 ton / 042 = 3.5 ton / 048 = 4 ton / 060 = 5 ton cooling

    good luck
