Abstract

A diagnostic system for a compressor is provided. The compressor includes a compression mechanism and a motor. The diagnostic system includes processing circuitry and memory and may be operable to differentiate between a low-side fault and a high-side fault by monitoring a rate of current rise drawn by the motor for a first predetermined time period following compressor startup. The diagnostic system may be operable to predict a severity level of a compressor condition based on a fault history stored in the memory.
