Maintain your S3QA-030K central air conditioner running efficiently with genuine OEM replacement parts from Repair Clinic. The S3QA-030K is a two-and-a-half-ton residential outdoor condensing unit using R-410A Puron refrigerant. Nordyne is the parent platform for Coleman HVAC, Gibson, and related manufactured home and residential HVAC brands. The S3QA-030K and S3QA-030KA are closely related configurations within the same Nordyne S3QA series. The dual run capacitor, contactor, and outdoor fan motor account for the vast majority of service calls. Repair Clinic stocks genuine Nordyne OEM parts for the S3QA-030K including the Nordyne capacitor parts, Nordyne contactor parts, Nordyne fan motor parts, and Nordyne high-pressure switch parts.

S3QA-030K: Two-And-A-Half-Ton 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 S3QA-030K. 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 S3QA-030K
Dual Run Capacitor for the S3QA-030K
The dual run capacitor provides starting and running torque for both the compressor and outdoor fan motor. A reading more than 10% below the rated value causes the compressor to hard-start. Match all three microfarad values from the installed capacitor label before ordering.
S3QA-030K Contactor
The contactor closes the 240-volt compressor circuit at every cooling cycle start. Pitted or burned contacts 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 S3QA-030K
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 S3QA-030K
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.

S3QA-030K Parts FAQ
What is the S3QA-030K and what ton size is it?
The S3QA-030K is a two-and-a-half-ton residential outdoor condensing unit using R-410A Puron refrigerant. Nordyne is the parent platform for Coleman HVAC, Gibson, and related manufactured home and residential HVAC brands. The S3QA-030K and S3QA-030KA are closely related configurations within the same Nordyne S3QA series.
Why does my S3QA-030K hum but not start?
A unit that hums but does not start has most commonly failed at the dual run capacitor. Test the capacitor with a digital capacitance meter before testing any other component.
Are Nordyne S3QA-030K and S3QA-030KA parts interchangeable?
The S3QA-030K and S3QA-030KA are closely related configurations within the same two-and-a-half-ton Nordyne S3QA series. Most service components including the dual run capacitor and contactor are typically shared between both configurations. Confirm the full model designation before ordering a replacement control board.
How often should I test the capacitor on the S3QA-030K?
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.
