Restore your NAC036AKA5 central air conditioner running efficiently with genuine OEM replacement parts from Repair Clinic. The NAC036AKA5 is a three-ton residential outdoor condensing unit using R-410A Puron refrigerant. ICP, Heil, Tempstar, Arcoaire, and WeatherKing are all International Comfort Products brand designations sharing the same platform engineering and fully interchangeable service components. The NAC036AKA5 is the three-ton configuration in the NAC series, above the two-ton NAC024AKA1 and below the four-ton NAC048AKC3. The dual run capacitor, contactor, and outdoor fan motor account for the vast majority of service calls. Repair Clinic stocks genuine ICP OEM parts for the NAC036AKA5 including the ICP capacitor parts, ICP contactor parts, ICP fan motor parts, and ICP high-pressure switch parts.

NAC036AKA5: 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 NAC036AKA5. 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 NAC036AKA5
Dual Run Capacitor for the NAC036AKA5
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.
NAC036AKA5 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 NAC036AKA5
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 NAC036AKA5
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.

NAC036AKA5 Parts FAQ
What is the NAC036AKA5 and what ton size is it?
The NAC036AKA5 is a three-ton residential outdoor condensing unit using R-410A Puron refrigerant. ICP, Heil, Tempstar, Arcoaire, and WeatherKing are all International Comfort Products brand designations sharing the same platform engineering and fully interchangeable service components. The NAC036AKA5 is the three-ton configuration in the NAC series, above the two-ton NAC024AKA1 and below the four-ton NAC048AKC3.
Why does my NAC036AKA5 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 ICP NAC036AKA5 differ from the NAC024AKA1 and NAC048AKC3?
The NAC036AKA5 is a three-ton unit between the two-ton NAC024AKA1 and four-ton NAC048AKC3 within the ICP NAC residential outdoor condensing unit series. The dual run capacitor carries different compressor-section microfarad ratings across all three tonnages.
How often should I test the capacitor on the NAC036AKA5?
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.
