Abstract:
An ice dispensing assembly in an appliance and a method of controlling a duct door in an ice dispensing assembly is provided. A duct door is actuated to dispense ice using a motor. The motor can be variably driven using an electrical signal having a plurality of different levels or slopes during the actuation of the duct door. The electrical signal can have an increasing slope when the duct door is actuated into an open position. When the duct door is held in the open position, a constant electrical signal can be applied to the motor. The constant value can be lower than a peak value of the increasing slope of the electrical signal. To return the duct door to a closed position, an electrical signal having a decreasing slope can be applied to the duct door motor.
