1. A method for cleaning a refrigeration coil of a refrigerated transportation container comprising:
detecting an indication of operational deterioration of a transportation container refrigeration system using one or more sensors to detect that refrigeration operations are deteriorating within the refrigerated transportation container and communicating associated deterioration information to a controller;
in accordance with a determination of a buildup of contaminants within the transportation container refrigeration system based on the associated deterioration information, the controller responds by removing power from non-fan components of the transportation container refrigeration system and implementing a cleaning operation comprising:
reversing a rotational direction of an airflow fan from a first direction to a second direction such that air is drawn over the refrigeration coil and expelled from the refrigerated transportation container using the airflow fan; and
reverting the rotational direction of the airflow fan to the first direction at a conclusion of the cleaning operation.
