Hi, We at James Purcell's Snow Globe repair have come across this more than once . Storing the globe upside down is the right way to store it if their is no air bubble in the globe . But if the air bubble comes in contact with the motor shaft ( not all of them are made of stainless steel ) so when the air makes contact with it, rust is the thing that causes the problem . In most cases the shaft getting wet then dry causing the shaft to rust then acting like sandpaper and chewing up the soft latex bushing . causing a slight vibration and also the liquid seeping in to the motor shorting it out and then not working at all . Some motors that have a working space inside of the globe have a short life which is at best should be seen by a Globe Tech. Who might be able to solve your problem . The public is not aware that some globes are reduced to next to nothing because if they are not sold in three years from the date of manufacture they might leak ,Motors quite working, Become air bubble burdened and they
can't be sold easily . Send an "E" ( thelmaandjim@eastlink.ca )
We will tell you your best choice !! Jim.
