This Avantco 17816965 evaporator fan motor is a perfect replacement for the one that came with select UDD, UBB, GDS, GDC, and CBE series 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 motor can prevent your unit from maintaining specifications and cause strain on other components, so be sure to replace it promptly.
