Abstract
A motorized damper and a control circuit for controlling the damper motor are described. More specifically, and in one embodiment, the control circuit includes a fresh food compartment cold control (FFCC) thermostatic switch, sometimes referred to herein as the FFCC thermostat. The temperature in the refrigerator fresh food compartment is measured by the FFCC thermostat, and when the FFCC thermostat determines that the temperature in the fresh food compartment is too warm, the FFCC thermostat closes providing a signal which energizes the damper motor. When the damper motor is energized, the motor rotates a cam which moves the damper door from a closed position to an open position. When the FFCC thermostat senses that the temperature in the fresh food compartment is acceptable, the FFCC thermostat opens which causes the motor to rotate the cam to close the damper door.
