This Avantco A Plus 44712188086 condenser motor is a direct replacement for the one that came with AP-23R and AP-49R reach-ins. The condenser motor 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.
