The Whirlpool W11430645 Refrigerator Water Inlet Valve controls water entering the refrigerator. It opens when water is needed for the ice maker or dispenser and closes to stop the water supply. Designed for compatible Whirlpool refrigerators, this replacement valve provides a proper fit and restores normal water flow when the original valve is damaged or worn. https://www.hnkparts.com/w11430645-whirlpool-valve
