A method for controlling power to a condenser fan of a transport refrigeration unit (TRU) includes disconnecting power to the condenser fan; detecting a fan voltage produced by back emf of the condenser fan; obtaining an input volume flow rate corresponding to airflow over a condenser in response to the fan voltage; comparing the input volume flow rate to a lower limit volume flow rate; disconnecting power to the condenser fan when the input volume flow rate is greater than the lower limit volume flow rate.
