Keep your Lennox 13ACD-036-230-02 central air conditioner running efficiently with genuine OEM replacement parts from Repair Clinic. The 13ACD-036-230-02 is a three-ton, 13 SEER R-22 residential outdoor condensing unit from Lennox’s 13ACD series. The run capacitor, contactor, and outdoor fan motor account for the vast majority of 13ACD-036-230-02 service calls. Annual capacitance testing before the cooling season is the most cost-effective preventive maintenance step on this platform. Repair Clinic stocks genuine Lennox OEM parts for the 13ACD-036-230-02 including the Lennox capacitor parts, Lennox contactor parts, Lennox fan motor parts, and Lennox high-pressure switch parts.

13ACD-036-230-02: Lennox Three-Ton 13 SEER R-22 Outdoor Condensing Unit Service
The Lennox 13ACD-036-230-02 is a three-ton 13 SEER R-22 outdoor condensing unit in the 13ACD residential product line. The 02 revision designation succeeds the 01 revision at the same three-ton 13 SEER 230-volt configuration. Most service components are shared between both revisions. The 13ACD-036-230-02 uses R-22 refrigerant requiring EPA 608 certified technicians for refrigerant circuit service. Annual capacitance testing of the run capacitor before the cooling season catches a weakening capacitor before it fails under peak summer load. The central air conditioner repair help section covers 13ACD capacitor testing and contactor diagnosis.
Most Replaced Parts on the Lennox 13ACD-036-230-02
Run Capacitor for the Lennox 13ACD-036-230-02
The 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, accumulating heat in the motor windings. Match all microfarad and voltage values from the installed capacitor label before ordering.
Lennox 13ACD-036-230-02 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 13ACD-036-230-02
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 13ACD-036-230-02
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.

Lennox 13ACD-036-230-02 Parts FAQ
What is the Lennox 13ACD-036-230-02 and what ton size is it?
The Lennox 13ACD-036-230-02 is a three-ton, 13 SEER R-22 residential outdoor condensing unit from Lennox’s 13ACD series. The 036 identifies 36,000 BTU three-ton capacity, 230 identifies the 230-volt power configuration, and 02 identifies the production revision within the 13ACD-036-230 platform.
Why does my Lennox 13ACD-036-230-02 hum but not start?
A unit that hums but does not start has most commonly failed at the run capacitor, which cannot provide adequate starting torque to the compressor or fan motor. Test the capacitor with a digital capacitance meter before testing the contactor or compressor.
What refrigerant does the Lennox 13ACD-036-230-02 use?
The 13ACD-036-230-02 uses R-22 refrigerant. R-22 is no longer produced for new equipment and requires EPA 608 certified technicians for any refrigerant circuit service using reclaimed R-22 supplies.
How is the Lennox 13ACD-036-230-02 different from the 13ACD-036-230-01?
The 13ACD-036-230-02 and 13ACD-036-230-01 are successive production revisions of the same three-ton 13 SEER Lennox condensing unit. Most service components including the capacitor, contactor, and fan motor are shared between both revisions. The control board may differ between revision 01 and revision 02.
