A shortage of refrigerant, often caused by leaks, forces the compressor to work excessively hard to achieve the desired cooling effect. The internal components of a compressor rely on precise tolerances and lubrication to function smoothly.

Similarly, voltage fluctuations are a major factor; operating a compressor on a voltage that is too low causes the motor to draw more current to maintain torque, while a voltage surge can cause a sudden, damaging spike in temperature and current. To meet this demand, the motor runs for extended periods at higher currents, generating excessive heat.
This friction generates intense local heat that can quickly overwhelm the system. A compressor is a heat engine, and like any machine running under load, it generates significant thermal energy during operation.

Overheating is not merely a symptom; it is a critical failure state that indicates a malfunction within the thermodynamic cycle or the mechanical system itself. If the heat production surpasses the rate of dissipation, the internal temperature climbs steadily, leading to a cascade of component stress.
