Restore your S3QA-036K central air conditioner running efficiently with genuine OEM replacement parts from Repair Clinic. The S3QA-036K is a three-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-036K is the three-ton configuration in the S3QA series, above the two-and-a-half-ton S3QA-030KA. 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-036K including the Nordyne capacitor parts, Nordyne contactor parts, Nordyne fan motor parts, and Nordyne high-pressure switch parts.

S3QA-036K: Three-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-036K. 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-036K
Dual Run Capacitor for the S3QA-036K
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-036K 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-036K
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-036K
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-036K Parts FAQ
What is the S3QA-036K and what ton size is it?
The S3QA-036K is a three-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-036K is the three-ton configuration in the S3QA series, above the two-and-a-half-ton S3QA-030KA.
Why does my S3QA-036K 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.
How does the Nordyne S3QA-036K differ from the S3QA-030KA?
The S3QA-036K is a three-ton unit while the S3QA-030KA is a two-and-a-half-ton unit in the same Nordyne S3QA series. The dual run capacitor carries different compressor-section microfarad ratings between the two tonnages.
How often should I test the capacitor on the S3QA-036K?
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.
