A method and apparatus for controlling the operation of a refrigeration system, for example, is provided which includes a first sensor for monitoring the sump temperature of a compressor used in conjunction with the refrigeration system, and a second sensor which monitors compressor ambient air temperature. The refrigeration system includes an electrically operable expansion valve and the sensors are employed in a control device operatively connected to the electrically controlled expansion valve to control the operating position of that valve. Refrigeration system operation can be controlled precisely, thereby maximizing the efficiency of the system, by monitoring the sump temperature and ambient temperature of the compressor.
