Abstract: The present disclosure relates to a heating, ventilation, and/or air conditioning (HVAC) unit including a condenser coil and a condenser fan assembly. The condenser fan assembly includes a first fan and a second fan, where the first fan and the second fan are each configured to operate to pull air through the condenser coil. The HVAC unit also includes a motor of the first fan including a housing and a shaft, where the motor is configured to operate to rotate the shaft in a first direction. The HVAC unit further includes a unidirectional bearing that is coupled to the shaft and a mounting assembly of the condenser fan assembly, where the unidirectional bearing is configured to block rotation of the shaft in a second direction that is opposite the first direction.
