This Avantco 17816407 axial condenser fan set is designed to fix a broken one on select UBB series back bar refrigerators. An essential part of your unit's refrigeration system, these fans circulate air through the condenser coil, cooling it down and helping the unit dissipate heat. If your fans aren't operating properly be sure to fix the issue fast, as a broken fan can lead to failures in other key refrigeration system components.
