WP4387764 - Whirlpool Refrigerator Capacitor

This Whirlpool Refrigerator Capacitor (WP4387764), a genuine part from the manufacturer, is essential for your refrigerator's compressor motor start-up. As an electrical energy storage device located near the compressor, the capacitor briefly stores and releases electrical charges. It provides the compressor motor with an extra surge of current needed to overcome inertia and start spinning from rest. Once operational, the capacitor discharges and plays a passive role in the circuit. Made up of conducting plates separated by an insulating dielectric material, this part is critical for the seamless operation of your refrigerator. Symptoms indicating the capacitor might be failing include the compressor struggling to start or failing to start entirely. A visibly popped or bulging capacitor also signals the need for immediate replacement. Confirm that your refrigerator's model number matches for compatibility before purchasing.
