When energized, the water inlet valve will release water from the supply line into the ice mold and the water dispenser in the refrigerator. If the ice maker is not making/dispensing ice, not dispensing water, or leaking, you may need to replace the water inlet valve. The water inlet valve is in the back section of your refrigerator and will need to be pulled out from the wall and make sure to disconnect both the water and power supply before starting your repair. 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.
