Abstract
A damper suitable for use in a refrigerator provides for linear motion of a damper plate toward and away from a damper seat. The damper plate may be driven by an axial lead screw attached to a small DC motor and may employ a non-foam gasket to reduce water absorption and possible formation of obstructing ice.
