Abstract
A method of detecting airflow blockage of a transport refrigeration system including the steps of: activating a heater powered by an electric generation device; measuring an output voltage of the electric generation device; determining a predicted heat output of the heater in response to the output voltage; determining a predicted temperature rise across the heater in response to the predicted heat output; detecting a measured temperature rise across the heater; and determining an airflow reduction percentage in response to the predicted temperature rise across the heater and the measured temperature rise across the heater.
