This is the ice actuator or ice actuator arm for your refrigerator. When you depress the actuator arm with a glass or bucket, ice is normally dispensed. If your current actuator arm is broken, missing, or if the ice dispenser isn’t dispensing ice, you may need to replace it. To access the actuator, you will first need to remove the dispenser assembly, and then remove the actuator from the assembly. Be sure to shut off the water and power source from your refrigerator before you begin this repair.
