Raymond K West Covina , CA August 29, 2023 Appliance: LG Refrigerator LSC27925ST Lg Refrigerator Lsc27925st / : Water to ice maker, but not to dispenser. How to replace Water Inlet Valve Assembly. I knew I had water going to the ice maker, but when I tried the water dispenser, I could hear a humming sound but got no water. So I ordered the correct LG part at AppliancePartsPros.com, and replaced the old water regulator unit. The water dispenser works great now. Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
