Look at the control panel to determine if the refrigerator has a Quick Ice button.
Press the Quick Ice button on the control panel, if it is present, to turn on the Quick Ice feature.
Press the Colder button, located to the left of the word "Freezer" to lower the temperature in the freezer. Each time the button is pressed the temperature setting will decrease one degree. Lowering the temperature in the freezer decreases the time to freeze water, resulting in increased ice production. This setting can be used on refrigerators with or without the Quick Ice setting to increase the production of ice.
