I'm glad you clarified that. I was wondering if I was doing something wrong with my snowglobes!! :D
Is it mechanical or electronic? If it's mechanical and stored in your basement, it's possible the metal gears etc are corroded due to ambient humidity. I'm not sure how to fix that other than taking it apart and cleaning it.
