Christi G Evergreen , CO January 06, 2022 The roller case and one wheel of the lower dishwasher rack melted. We ordered one wheel and the case that holds them with great support from The Appliance Parts Pros. Using one original wheel, we snapped the parts together. We used the other three cases as examples and snapped the new case into place. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
