1. A transport refrigeration system, comprising:
first and second refrigeration circuits configured to cool first and second transport compartments, respectively;
an electric machine that powers the first and second refrigeration circuits; and
a controller configured to:
monitor a temperature of the electric machine;
reduce a cooling capacity of a selected one of the first and second refrigeration circuits based on the temperature exceeding a first threshold; and
in a first control mode:
determine a difference between a respective current temperature and a respective setpoint temperature of each of the transport compartments; and
select the refrigeration circuit whose associated transport compartment has the greatest difference as the selected refrigeration circuit.
