Restore your 14ACX-030-230-A18 central air conditioner running efficiently with genuine OEM replacement parts from Repair Clinic. The 14ACX-030-230-A18 is a two-and-a-half-ton, 14 SEER R-410A residential outdoor condensing unit using R-410A Puron refrigerant. The 030 identifies approximately 30,000 BTU two-and-a-half-ton capacity, 230 identifies the 230-volt power configuration, and A18 identifies the production revision within the 14ACX-030-230 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 14ACX-030-230-A18 including the Lennox capacitor parts, Lennox contactor parts, Lennox fan motor parts, and Lennox high-pressure switch parts.

14ACX-030-230-A18: Two-And-A-Half-Ton, 14 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 14ACX-030-230-A18. 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 14ACX-030-230-A18
Dual Run Capacitor for the 14ACX-030-230-A18
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.
14ACX-030-230-A18 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 14ACX-030-230-A18
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 14ACX-030-230-A18
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.

14ACX-030-230-A18 Parts FAQ
What is the 14ACX-030-230-A18 and what ton size is it?
The 14ACX-030-230-A18 is a two-and-a-half-ton, 14 SEER R-410A residential outdoor condensing unit using R-410A Puron refrigerant. The 030 identifies approximately 30,000 BTU two-and-a-half-ton capacity, 230 identifies the 230-volt power configuration, and A18 identifies the production revision within the 14ACX-030-230 platform.
Why does my 14ACX-030-230-A18 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 14ACX-030-230-A18 differ from the 13ACX-030-230-13?
The 14ACX-030-230-A18 is a 14 SEER R-410A unit while the 13ACX-030-230-13 is a 13 SEER R-22 unit, both at two-and-a-half-ton capacity. The 14ACX and 13ACX are different efficiency-tier and refrigerant platforms with different component specifications.
How often should I test the capacitor on the 14ACX-030-230-A18?
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.
