Keep your AFAIR10B30-A-1 central air conditioner running efficiently with genuine OEM replacement parts from Repair Clinic. The AFAIR10B30-A-1 is a two-and-a-half-ton R-22 residential outdoor condensing unit using R-22 refrigerant. The AFAIR10B30-A-1 is part of the Lennox Aire-Flo residential product line. The 30 identifies approximately 30,000 BTU two-and-a-half-ton capacity, placing it between the two-ton AFAIR10B24-1 and the three-ton AFAIR10B36-B-1 in the Aire-Flo tonnage lineup. The dual run capacitor, contactor, and outdoor fan motor account for the vast majority of service calls. Repair Clinic stocks genuine Lennox Aire-Flo OEM parts for the AFAIR10B30-A-1 including the Lennox capacitor parts, Lennox contactor parts, Lennox fan motor parts, and Lennox high-pressure switch parts.

AFAIR10B30-A-1: Two-And-A-Half-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 AFAIR10B30-A-1. 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 AFAIR10B30-A-1
Dual Run Capacitor for the AFAIR10B30-A-1
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.
AFAIR10B30-A-1 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 AFAIR10B30-A-1
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 AFAIR10B30-A-1
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.

AFAIR10B30-A-1 Parts FAQ
What is the AFAIR10B30-A-1 and what ton size is it?
The AFAIR10B30-A-1 is a two-and-a-half-ton R-22 residential outdoor condensing unit using R-22 refrigerant. The AFAIR10B30-A-1 is part of the Lennox Aire-Flo residential product line. The 30 identifies approximately 30,000 BTU two-and-a-half-ton capacity, placing it between the two-ton AFAIR10B24-1 and the three-ton AFAIR10B36-B-1 in the Aire-Flo tonnage lineup.
Why does my AFAIR10B30-A-1 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 AFAIR10B30-A-1 fit within the Aire-Flo tonnage lineup?
The AFAIR10B30-A-1 is a two-and-a-half-ton unit positioned between the two-ton AFAIR10B24-1 and the three-ton AFAIR10B36-B-1 in the Lennox Aire-Flo R-22 series. The run capacitor carries different compressor-section microfarad ratings across all three tonnages. Never substitute capacitor specifications between the 24, 30, and 36 configurations.
How often should I test the capacitor on the AFAIR10B30-A-1?
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.
