    IM trying to get used fans to work.

    I have taken some fans out of a rack mounted computer cabinet. As far as I can see the power goes from the 120 wall to the 4 fans that are in the top of the cabinet. Frankly its hard to see as the rack is still in use and seeing the wires perfectly is very hard. Every once and a while we replace these fans.
    I have a bunch of them now and want to use them in other places to cool things. But when I hook 120 volts up to one of the fans outside the cabinet nothing happens. That is, any of the fans that I have taken out dont seem to work if I hook 120 Volts to them.

    Here are the specs on the fans.
    Xinruilian
    Axial AC Fan
    Model: RAL 1238S2

    100-125Vac~ 50/60Hz
    0.20A Class B
    IMPEDANCE PROTECTED

    Should this work with 120 Volts? From what I see they should work.
    120 volts 60hz 0.20Amps. Looks like no big woop.

    Regards and thanks.

    Yes, it's designed to work with 120VAC 60 Hz. Why it doesn't I can't see
    from here.

    OK thanks all.
    I will keep checking the fans. Some of them worked when we took them out. Maybe I just chose the wrong ones.

    Thanks.

    Suppose these fans are replaced for some reason. Maybe they are replaced for
    not working anymore. Replacing every once a while seems to point to a flaw
    in the design. Either the cabinets or the fans (or both) are not equal to
    their tasks. But that's another tale.

    ** Do you even own a multimeter??

    The winding in the motor has a resistance.

    Petrus.
    We replace all the fans at once because it takes some work to take them out.. If one is going they will probably all go soon enough. We would rather just spend a few extra dollars on the new fans than the labour involved in changing one fan. I suppose its the same as when they replace all the streetlights on your street. They have a life and some will last longer than others, it is best to do it all at once when you have the time and prevent future problems.

    Phil IM sure you didnt mean it but your comment ** Do you even own a multimeter?? seems kinda rude. Im sure you didnt mean it that way.
    It might be better to provide some advice on resolving the problem specifically or try to answer the OP question. I do find people waste a lot of timenot answering questions, and giving all sorts of information that is not related to the questions or passing moral judgements on people. Rather you could have said if you have a multimeter you could check the fan and see if there is any resistence through it. This will tell you if it is working or not. Somethig like that, Im no expert.

    Thanks for contributing though.

    Just out of curiosity, why did you keep the fans that didn't work?

    ** I very much meant it to be rude.
    ** Wrong - the correct way is to judge the post first.

    Is the poster asking a question that is on topic and makes sense.

    Or is it yet another time wasting troll like yours.

    ** Ask a stupid question and you WILL get judged.

    What an arrogant little **** you are demanding your stupid question gets
    answered the way YOU want.

    **** you.
    ** Is this retard for real ??
    ** Piss off - Goggle Groups wanker.
