The water inlet valve on your refrigerator allows water to enter the ice maker and water dispenser. If your ice maker or water dispenser is not functioning properly, or you notice a leak, you may need to replace the single outlet valve. This single outlet valve has 1/4-inch compressions fittings and is intended for use with refrigerators that make crescent-shaped ice cubes. As per the manufacturer, this valve has a new quick connection. You must cut the retaining nut off your current plastic water line, and gently push it into the new valve. Be sure to disconnect the water and power sources from the refrigerator before you begin this repair.
