What is the function of a refrigerator capacitor and how does it contribute to the overall operation of the appliance?

A refrigerator capacitor helps the compressor start and run efficiently by storing and releasing electrical energy. It provides the necessary power boost to kick-start the compressor, which is essential for cooling the refrigerator. Without the capacitor, the compressor may struggle to start or fail to operate properly, leading to issues with cooling the refrigerator.
