Compressor diagnostic system

摘要

A compressor (10) includes a motor protector (54) which stops the compressor's motor when it senses an out of specification condition. A diagnostic system (100) monitors the status of the motor protector (54). The diagnostic system (100) includes logic circuitry (104) that diagnoses the type of problem the compressor (10) is having based upon the running times and status of the motor in conjunction with the times and status of the motor protector (54).
