Common causes of A/C compressor failure and the key features of MSG Equipment’s MS111 bench for testing compressors off the vehicle.
The main causes of A/C compressor failure are moisture and dust entering the system, low oil level and overheating. Early diagnosis can prevent costly repairs, while a seized compressor has to be replaced entirely.
MSG Equipment’s MS111 bench checks new and remanufactured compressors off the vehicle, measuring parameters such as pressure, evaporation and condensation temperatures and drive speed.
- adapters for all compressor types from different manufacturers
- LCD touch-screen control and automatic air and refrigerant evacuation
- smooth speed adjustment, saving and printing of results
Oil condition should be checked before diagnostics: clear oil indicates a healthy unit, while a grey tint and particles mean the compressor needs to be dismantled.
