Compressor Run Capacitor
The GSXC18 uses an ECM fan motor that does not require a capacitor, but the Copeland scroll compressor relies on a dedicated run capacitor to provide the necessary phase-angle displacement for its start windings. When this capacitor suffers a dielectric breakdown, the compressor motor cannot generate the magnetic torque required to overcome static head pressure, resulting in a locked rotor state or a failure to initiate the compression cycle. Because the fan continues to spin, the user perceives the unit as 'running' despite the lack of refrigerant mass flow and subsequent heat exchange.
