This Avantco A Plus 44712188296 evaporator motor is a direct replacement for the one that came with AP series reach-ins. The evaporator 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.
