Carol A Walsenburg , CO June 03, 2023 Appliance: Model AP3994981 (WD12X10231) Broken roller assemblies Used pliers to pull off broken parts - lined up replacement wheel assembly and gently tapped it in place as I have done previously when I had four broken assemblies - easy-peasy. Easy lookup on this site - quick and painless purchase and delivery of the product. Took me about one minute to replace the two broken assembly pieces.
