Manual? from Amazon (not spamming!)

The spinning sound may be from the takeup reel spinning. Is film in it? Some cameras spool all the film from the cartridge on to the takeup reel. As we take photos the film is pulled into the cartridge, a safety feature for an accidental opening of the camera back.

if none of the above applies to your camera, then it might need repair. Cost of repair could be much more than it is worth. If you like the camera look at KEH.com for another one of that model.
