This Avantco 17813227 door bushing is a direct replacement for the one that came with select Avantco GDC, GDW, and GDICE series units. It is a vital part of your unit's door assembly, working to create a firm door seal and keep the cabinet set to the right temperature. A broken or malfunctioning door hinge can prevent your unit from maintaining specifications and cause strain on other components, so be sure to replace it promptly.
