Abstract
A device for controlling a damper in an appliance is disclosed comprising a motor having a rotatable shaft extending therefrom which is operatively connected to a plate of the damper, a control circuit which transmits current to the motor to rotate the shaft and in turn rotate the plate to a first position and to a second position, and a dynamic brake operatively connected to the motor, which acts to reduce rotation of the shaft when the circuit supplying current to the motor is opened.
