WR55X31290 - GE Refrigerator Capacitor

The WR55X31290 (WR55X31290) is a genuine part manufactured by GE for use in their refrigerators. This component, sometimes referred to as an electrical energy storage device, is compatible with various GE refrigerator models.

Located near the compressor, the capacitor's primary function is to briefly store and release electrical charges that assist in starting the compressor motor. This process involves providing an extra surge of current needed to overcome inertia and initiate the motor's spinning from a resting state. Once the compressor is operational, the capacitor discharges its electrical function and becomes a passive component within the circuit.

The capacitor is composed of conducting plates separated by an insulating dielectric material. If this part fails, it can prevent the compressor from starting up. Visible evidence of a failing or broken capacitor may include a popped or bulging appearance, indicating the need for replacement.

The role and location of the capacitor can vary depending on your refrigerator's model number. Therefore, it's crucial to verify the compatibility of this part with your specific appliance model before purchasing. This part is instrumental in ensuring the compressor motor receives the temporary jolt of power needed for its initial spin-up.
