A system and method for determining a fault condition in a compressor is provided. The current of a motor drive powering the compressor and the outdoor ambient temperature are measured and used to determine if a fault condition or a potential fault condition is present in the compressor. If a fault condition is determined to be present, the compressor can be shutdown to avoid damage to the compressor. If a potential fault condition is determined, remedial action can be taken to attempt to prevent the fault condition from occurring and shutting down the compressor.

System and method for detecting a fault condition in a compressor

A system and method for starting a compressor is provided. An amount of liquid refrigerant that is located in an oil sump of the compressor is determined. Using the determined amount of liquid refrigerant, a starting algorithm for the compressor is selected. The selected starting algorithm is configured to remove the determined amount of liquid refrigerant from the oil sump before the compressor reaches a preselected operating speed. The selected starting algorithm is then executed to start the compressor.
