Maintain your 13ACX-036-230-2 central air conditioner running efficiently with genuine OEM replacement parts from Repair Clinic. The 13ACX-036-230-2 is a three-ton, 13 SEER R-410A residential outdoor condensing unit using R-410A Puron refrigerant. The 13ACX designation identifies a Lennox 13 SEER R-410A residential outdoor condensing unit series. The 036 identifies three-ton capacity, 230 identifies the 230-volt power configuration, and 2 identifies the production revision. The dual run capacitor, contactor, and outdoor fan motor account for the vast majority of service calls. Repair Clinic stocks genuine Lennox OEM parts for the 13ACX-036-230-2 including the Lennox capacitor parts, Lennox contactor parts, Lennox fan motor parts, and Lennox high-pressure switch parts.

13ACX-036-230-2: Three-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 13ACX-036-230-2. 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 13ACX-036-230-2
Dual Run Capacitor for the 13ACX-036-230-2
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.
13ACX-036-230-2 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 13ACX-036-230-2
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 13ACX-036-230-2
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.

13ACX-036-230-2 Parts FAQ
What is the 13ACX-036-230-2 and what ton size is it?
The 13ACX-036-230-2 is a three-ton, 13 SEER R-410A residential outdoor condensing unit using R-410A Puron refrigerant. The 13ACX designation identifies a Lennox 13 SEER R-410A residential outdoor condensing unit series. The 036 identifies three-ton capacity, 230 identifies the 230-volt power configuration, and 2 identifies the production revision.
Why does my 13ACX-036-230-2 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 Lennox 13ACX-036-230-2 differ from the 14ACX-036-230-10?
The 13ACX-036-230-2 is a 13 SEER unit while the 14ACX-036-230-10 is a 14 SEER unit, both at three-ton capacity. The higher-efficiency 14ACX series may use different run capacitor specifications than the 13ACX series at the same tonnage.
How often should I test the capacitor on the 13ACX-036-230-2?
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.
