Is your LG refrigerator not dispensing water properly? This genuine OEM water inlet valve might be exactly what you need to fix it. This isn't some generic knockoff - it's the real deal replacement part that matches your LG's original specifications. The part number is 5221JA2006D, and it replaces several other common part numbers too (1266849, AJU34125501, AJU34125513, AP4445614). It measures about 4 inches long, 6.75 inches wide, and 3 inches high. Before you order, definitely double-check your refrigerator's model number to make sure this is the right fit - we've seen too many returns because people ordered the wrong part. If you're not 100% sure, just message the seller with your model number and they'll confirm compatibility. Installation's pretty straightforward if you're handy, and they even encourage customers to share 60-second installation videos to help others. One pro tip: if you're worried about authenticity, ask the seller for pictures of the actual part front and back before buying. This valve controls water flow into your fridge for the ice maker and water dispenser, so if you're getting weak water flow, no ice, or constant running water sounds, this could be your solution. Much cheaper than calling a repair service if you can handle the installation yourself!
