Bogdan M East Berlin , CT April 29, 2019 Top shelf adjuster replacement. The replacement part kit included two complete adjusters, which seem sturdier (metal) than the original plastic ones. There were no instructions included in the package and online pictures were not very clear, so it took about 1/2 hour to replace. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
