1. A system comprising:a compressor operable in a refrigeration circuit;
a first sensor detecting first data indicative of an operating condition of a high-pressure side of the refrigeration circuit;
a second sensor detecting second data indicative of an operating condition of a low-pressure side of the refrigeration circuit;
processing circuitry configured to: (i) receive the first data and the second data, (ii) determine a fault based on at least one of the first data and the second data, (iii) categorize the fault as one of a mild low-side fault, a severe low-side fault, a mild high-side fault, and a severe high-side fault based on the first data and the second data, (iv) operate the compressor in a limp-along mode by at least one of restricting power to the compressor and reducing a capacity of the compressor in response to categorizing the fault as one of the mild high-side fault and the mild low-side fault, and (v) shutting down the compressor in response to categorizing the fault as one of the severe high-side fault and the severe low-side fault.
