    Induction fan for a carrier 48gp
    I have replaced the induction motor from my carrier 48gp. The guy that took it out (HVAC "freind") will now not answer the phone. I have the unit bolted in and I know where a couple of the wires go, but I need help with the others. There is a yellow, green (ground), brown, and purple coming off the fan assembly its self. I do not have any clue where the purple wire goes. Can you help??

    Is it the right fan? It has a extra wire that the other did not have?

    If it does have an extra wire what do I do??

    Most fans have the same bolt pattern, this does not necessarily mean it is the right fan, some fans are for 2 stage gas valves thus the 3rd wire.

    Does the motor have a wiring diagram label present? The brown suggests a capacitor may be required.

    No I got the motor from a wholesale yard they would not give me any instructions because they do not sell to the public

    I am in drywall sales so this can be a dumb question... do I have to hook all wires up?
    I know dumb

    Is there ANY nomenclature (brand, mfg. #, h/p, voltage, r.p.m. etc.) on the motor?
  • Nov 18, 2009, 04:58 PM
    Joshdta

    Where do you have he other color wires hooked now?
  • Nov 18, 2009, 04:58 PM
    sampson79

    The part is from the carrier replacement parts div. The fan is bolted in so I do not have it next to me at this time

    Green grounded
    Yellow is hooked to a set of four prongs sitting to the right of the mother board (capacitor?)
    And the brown is hooked into the mother board at the top right

    Do these colors match the previous motor?
  • Nov 18, 2009, 05:02 PM
    Joshdta

    Can you post a pic of where you have the yellow going?
  • Nov 18, 2009, 05:02 PM
    sampson79

    That's the problem the guy took the last one and like an idiot I did not take a pic before he started

    Is this a package unit?

    You are taking quite a gamble if you power this motor without verifying correct wiring. It could be a 2-speed motor as Josh said, or it may require a capacitor (the brown lead suggests it does). If you release the genie from the motor, you will never catch him.

    As in ac and heating
  • Nov 18, 2009, 05:08 PM

    As in outside, ac and heat in one.

    I would think that a carrier supply house would get me the correct motor
  • Nov 18, 2009, 05:11 PM
    Joshdta

    Look on the back of the door, the wiring diagram will be there you can see how many wires came off the old motor and where they go.
  • Nov 18, 2009, 05:11 PM
    sampson79

    Yes it is Ac and Heating out side

    It may be the correct replacement, even if it isn't identical to the original. Sometimes change is good.

    Kc you probably do more with carrier then me, do they have package units with 2 speed motors?
  • Nov 18, 2009, 05:14 PM
    sampson79

    What if its two speed then can I hook it up to a single speed unit
  • Nov 18, 2009, 05:16 PM
    Joshdta

    I have never seen a 2 speed fan on a package unit. Did you find the wire diagram on the back of the door?

    Not that I have seen, but some have a capacitor wired as such: brown to CAP1, yellow + L1 to CAP2, purple to L2. I have seen others with yellow & purple reversed.

    I am looking at it now
    The fan says that it is 23 volt
    60 htz
    3450 Rpm
    1/16 HP
    And made by AO smith

    The diag has
    v10
    Yel
    Brn
    Green
    Leaving the capacitor
  • Nov 18, 2009, 05:23 PM
    Joshdta

    If it has just 1 rpm listed it is not 2 speed. If you have 2 that go to the cap, then you only have 1 left. No common that way.
  • Nov 18, 2009, 05:24 PM
    Joshdta
    Is there a purple wire anywhere on that diagram?
  • Nov 18, 2009, 05:24 PM
    sampson79

    I can't believe I forgot and this might help you guys
    There is a cord that has blue white and red running into a female end that plugs into the mother board.
  • Nov 18, 2009, 05:25 PM
    sampson79

    No not that I see
    What is V10 (power?)
  • Nov 18, 2009, 05:28 PM
    Joshdta

    OK so you have a blue and a white. That plug to the board? That should be the power. Then the yellow and the purple should go to the cap. And the green is ground.
  • Nov 18, 2009, 05:28 PM
    sampson79

    I think he marked the Brown
    What is the cap??
  • Nov 18, 2009, 05:30 PM
    sampson79
    Capacitor... sorry
    Is that the two four prongs sitting to the right of the board?

    I forgot about the brown wire I must go to the capacitor also. I am trying to find you wireing diagram online.
  • Nov 18, 2009, 05:35 PM
    sampson79

    Yes I am with you know
    There is a yellow running to the cap already not the one from the fan... so an additional yellow and the brown go to the cap.
