If the condenser coils are clogged with dust, dirt, or debris, the heat transfer process is inhibited. Additionally, restrictions in the suction line or a failing expansion valve can starve the compressor of refrigerant, causing the motor to overwork without the cooling effect of the evaporating fluid.
Addressing High Current and Extended Runtime Issues to Prevent Overheat
The internal components of a compressor rely on precise tolerances and lubrication to function smoothly. If the oil level is low due to a leak or degradation due to contamination, the bearings and pistons begin to grind.
A compressor is a heat engine, and like any machine running under load, it generates significant thermal energy during operation. According to Joule’s law, resistance converts electrical current into heat energy.
Addressing High Current and Extended Runtime Issues
Mechanical and Electrical Failures Beyond refrigerant dynamics, mechanical wear and electrical anomalies are significant contributors to thermal failure. 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.
