ABSTRACT:
A system includes a compressor having a shell and a motor disposed within the shell. A first sensor is provided for monitoring a discharge temperature of the compressor, a second sensor is provided for monitoring a temperature of the motor, and a third sensor is provided for monitoring at least one of current and voltage. Processing circuitry receives sensor data from the first sensor, the second sensor, and the third sensor and processes the sensor data to diagnose the compressor.
