Terrance B Bemidji , MN December 18, 2016 Appliance: LG Refrigerator LRFD21855ST Lg Refrigerator Lrfd21855st / Astclga: Not making ice. How to replace Refrigerator Water Inlet Valve Assembly. The first thing I tried was thawing out the water tube to the icemaker. When that didn't fix the problem I realized the water valve needed replacing. I watched the video here and the whole process went very smoothly. I couldn't have done it without AppliancePartsPros. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
