What is the primary risk of using a run capacitor that is not functioning properly?

The primary risk of using a run capacitor that is not functioning properly is compressor overheating. A properly functioning run capacitor helps start the compressor and keep it running efficiently by providing the necessary phase shift in AC motors. When the capacitor fails, the compressor may struggle to start or maintain operation, leading to increased motor current draw. This excessive current can cause the compressor to generate more heat than it normally would, resulting in overheating. Over time, this can lead to thermal overload, reduced compressor lifespan, or complete compressor failure. Thus, maintaining the proper functionality of the run capacitor is critical for the compressor’s operational reliability and longevity.
