Keep your GSX130301LB central air conditioner running efficiently with genuine OEM replacement parts from Repair Clinic. The GSX130301LB is a two-and-a-half-ton, 13 SEER R-410A residential outdoor condensing unit using R-410A Puron refrigerant. The 030 identifies approximately 30,000 BTU two-and-a-half-ton capacity and LB identifies the production configuration within the GSX130301 series. The dual run capacitor, contactor, and outdoor fan motor account for the vast majority of service calls. Repair Clinic stocks genuine Goodman OEM parts for the GSX130301LB including the Goodman capacitor parts, Goodman contactor parts, Goodman fan motor parts, and Goodman high-pressure switch parts.

GSX130301LB: Two-And-A-Half-Ton, 13 Seer R-410A Outdoor Condensing Unit Service
Annual capacitance testing of the dual run capacitor before the cooling season is the most cost-effective preventive maintenance step for the GSX130301LB. Match all microfarad values from the installed capacitor label before ordering a replacement. The central air conditioner repair help section covers capacitor testing and contactor diagnosis for this platform.
Most Replaced Parts on the GSX130301LB
Dual Run Capacitor for the GSX130301LB
The dual run capacitor provides starting and running torque for both the compressor and outdoor fan motor. A capacitor reading more than 10% below its rated microfarad value causes the compressor to hard-start. Match all three microfarad values from the installed capacitor label before ordering.
GSX130301LB Contactor
The contactor closes the 240-volt compressor power circuit at every cooling cycle start. Pitted or burned contact surfaces generate heat that transfers to the compressor motor terminals. Replace a contactor with visibly eroded contacts before compressor winding damage occurs.
Outdoor Fan Motor for the GSX130301LB
The outdoor fan motor pulls air through the condenser coil. Test the run capacitor before ordering a replacement motor, as a failed capacitor produces identical slow-start symptoms at a fraction of the motor replacement cost.
High-Pressure Switch for the GSX130301LB
A high-pressure switch that trips repeatedly under normal ambient conditions points to a blocked condenser coil, failed fan motor, or refrigerant overcharge rather than a failed switch diaphragm.

GSX130301LB Parts FAQ
What is the GSX130301LB and what ton size is it?
The GSX130301LB is a two-and-a-half-ton, 13 SEER R-410A residential outdoor condensing unit using R-410A Puron refrigerant. The 030 identifies approximately 30,000 BTU two-and-a-half-ton capacity and LB identifies the production configuration within the GSX130301 series.
Why does my GSX130301LB hum but not start?
A unit that hums but does not start has most commonly failed at the dual run capacitor, which cannot provide adequate starting torque to the compressor or fan motor. Test the capacitor with a digital capacitance meter before testing any other component.
How does the Goodman GSX130301LB differ from the GSX130301BA?
The GSX130301LB and GSX130301BA are different production configuration suffixes within the same two-and-a-half-ton GSX130301 platform. The dual run capacitor, contactor, and outdoor fan motor are typically shared between both configurations. The control board may differ between the LB and BA suffixes.
How often should I test the capacitor on the GSX130301LB?
Test the capacitor annually before the cooling season. A reading more than 10% below the rated microfarad value indicates a weakening capacitor that should be replaced before it fails under peak summer load.
