It is not normal for the paddle not to move in these units. First we have to determine weather the paddle is striped or the gear is stripped. At the bottom of the paddle there is a hole that attaches to the turning gear on the machine. Look and see if it still matches the sprocket
in the bottom of the ice cream maker. If it does not still match I would suggest buying a new paddle. You can purchase a new paddle from Cuisinart for $8.00 and here is a link to the page. http://www.cuisinart.com/parts/ice_cream/ice-20.html
However, if it is not the paddle please post back to this thread and I will see if it is worth changing out the bottom gear.
