This Avantco 17815868 condenser coil is a perfect replacement for the one that came with Avantco A-19F-HC, GDW-23-BBC, and GDW-23-BB units. It is a vital part of your unit's refrigeration system, working with the other components to help your unit dissipate heat and keep the cabinet set to the right temperature. A broken or malfunctioning coil can prevent your unit from maintaining specifications and cause strain on other components, so be sure to replace it promptly.
