Fridge capacitors are essential components in refrigerators, playing a crucial role in the appliance's operation. They store and release electrical energy to start the compressor motor, ensuring the cooling cycle begins effectively. Typically found near the compressor, these capacitors help manage the motor's power surge at startup, reducing wear and enhancing efficiency. Over time, capacitors can degrade, leading to compressor issues or failure, making regular maintenance important to ensure the refrigerator runs smoothly and efficiently.
