ABSTRACT:
The failure of compressors due to their most common causes of failure are avoided by monitoring the operation of a compressor and operating or locking off the compressor where appropriate. Specifically, the system in run after a predetermined number of pump-downs without a call for cooling and the compressor is locked off if it cycles a predetermined number of times within a preset time period or if a low pressure situation is sensed during a call for cooling.
