If the condenser fan motor on your Avantco open-air merchandiser is broken or no longer working properly, be sure to replace it immediately with this Avantco 18939813 condenser fan motor for BMAC-26HC, WMAC-26HC, and MCAC-36 series units. The condenser fan motor is incredibly important to the functionality of your refrigeration unit, because it works to turn the fan blades (sold separately) and blow air across the condenser coil (sold separately), where it cools the refrigerant. If it is not functioning properly, the condenser will overheat, causing the system to eventually get hot enough to burn and emit an odor, and you will end up spending more money in the long run.
