Keep your 13ACX-036-230-13 central air conditioner running efficiently with genuine OEM replacement parts from Repair Clinic. The 13ACX-036-230-13 is a three-ton R-22 residential outdoor condensing unit. The unit uses R-22 refrigerant requiring EPA 608 certified technicians for any refrigerant circuit service. The 036 identifies 36,000 BTU three-ton capacity, 230 identifies the 230-volt power configuration, and 13 identifies the production revision within the 13ACX-036-230 platform. 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-036-230-13 including the Lennox capacitor parts, Lennox contactor parts, Lennox fan motor parts, and Lennox high-pressure switch parts.

13ACX-036-230-13: Three-Ton R-22 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-036-230-13. 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.

Dual Run Capacitor for the 13ACX-036-230-13
The dual run capacitor provides starting and running torque for both the compressor and outdoor fan motor in a single can. A capacitor reading more than 10% below its rated microfarad value causes the compressor to hard-start, accumulating heat in the motor windings. Match all three microfarad values from the installed capacitor label before ordering.
13ACX-036-230-13 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 13ACX-036-230-13
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-036-230-13
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-036-230-13 Parts FAQ
What is the 13ACX-036-230-13 and what ton size is it?
The 13ACX-036-230-13 is a three-ton R-22 residential outdoor condensing unit from Lennox’s 13ACX series. The unit uses R-22 refrigerant requiring EPA 608 certified technicians for any refrigerant circuit service.
Why does my 13ACX-036-230-13 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.
How is the Lennox 13ACX-036-230-13 different from the 13ACD-036-230-02?
The 13ACX and 13ACD are different Lennox product series at the same three-ton 230-volt R-22 configuration. Always confirm the full model designation including the ACX or ACD series prefix from the unit data plate before ordering a replacement control board.
How often should I test the capacitor on the 13ACX-036-230-13?
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.
