Which outcome occurs when a hermetic refrigeration compressor loses its refrigerant charge during operation?

💡 Explanation

When refrigerant levels are low, compressor motor loses cooling provided by the refrigerant because the mass flow and phase change of the refrigerant decreases significantly, reducing heat transfer and causing temperatures to rise leading to motor overheating. Therefore overheating occurs, rather than valve failure, bearing seizure, or capacitor burnout, all of which result from different operational faults.
