The LG Refrigerator water inlet valve opens the water supply to allow water to flow into the dispenser. If you have a faulty valve, it won't open, and water will not dispense. If a frozen water supply is the issue, you can unplug the appliance and allow the tube to defrost. This includes the primary and secondary valves, along with the wire harness. Luckily, this is a part that you can buy and replace yourself with these step-by-step instructions.
