    I'm working on a cheap Galaxy Box Fan that stopped working.
    I have found what I believe to be a small blown fuse, inline with one of the power feeds.
    I tried to find it on ALLDATASHEET, but came up blank.

    It looks to be ceramic, about 1/2" long with brownish gold lettering, and brownish gold tips on either end,. The info includes:
    <PS>E
    115 C 2A
    M N110
    069

    Continuity test was negative (no conductivity).

    Have I identified this correctly, is it a small fuse?

    Thanks,
    Gary

    It does sound as if it might be a 2 amp fuse. The question now is: why did it blow? If you have a meter, you might check by seeing what the resistance through the coils is. If it is 0, or very close, the motor may have gone bad.

    If you just want to see, go to a hardware store and find an inline fuse holder. Get a 2 amp 120 volt fuse to go in it, and put the fuseholder in with wire nuts. If that fuse blows, consider a new fan.

    This might be one of those one-time circuit interrupters. It works like a fuse, except it is temperature dependent and not just current heating a wire dependence (fuse).
    The question then becomes, why did it clear? Stalled fan motor? Overtemp. area?
    Replacing with a slo-blo fuse of 2A. is a good fix.
