Abstract

An ice dispenser has a duct cap and a controller to control movement of the duct cap. The controller includes a guide, a first control surface, and a second control surface. A first frictional force between the guide and the first control surface is greater than a second frictional force between the guide and the second control surface. The first frictional force controls the duct cap to move at a first rate and the second friction force controls the duct cap to move at a second rate faster than the first rate.
