S3QA-036KA: 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-036KA. 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-036KA
Dual Run Capacitor for the S3QA-036KA
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.
S3QA-036KA 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 S3QA-036KA
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-036KA
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-036KA Parts FAQ
What is the S3QA-036KA and what ton size is it?
The S3QA-036KA 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. Service components for the S3QA-036KA are interchangeable with equivalent Nordyne platform models at the same tonnage configuration.
Why does my S3QA-036KA 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.
What brand family does the Nordyne S3QA-036KA belong to?
Nordyne is the parent platform for Coleman HVAC, Gibson, and other residential HVAC brands. The S3QA-036KA and its Coleman HVAC equivalent at the same configuration share the same platform engineering with interchangeable service components.
How often should I test the capacitor on the S3QA-036KA?
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.
