A struggling motor drawing high current due to a failing start relay or a jammed rotor will heat up rapidly. A unit that is neglected or placed in a hostile environment will inevitably fail long before one that is properly maintained and installed.
Common Signs of Compressor Overheat and How to Prevent Failure
If the condenser coils are clogged with dust, dirt, or debris, the heat transfer process is inhibited. 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.
Conversely, overcharging the system results in liquid refrigerant flooding back to the compressor, a condition called slugging, which can cause mechanical damage and severe overheating. When a compressor overheats, the underlying issue is almost always a breakdown in the system’s ability to manage heat.
Common Signs of Compressor Overheat and How to Prevent Failure
A shortage of refrigerant, often caused by leaks, forces the compressor to work excessively hard to achieve the desired cooling effect. Oil is responsible for reducing friction, sealing internal components, and carrying heat away from critical areas.
