Keep your AFAIR10B36-B-1 central air conditioner running efficiently with genuine OEM replacement parts from Repair Clinic. The AFAIR10B36-B-1 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 AFAIR10B36-B-1 and AFAIR10B36-B are successive revisions of the same three-ton Aire-Flo platform, and the AC10B36-B is a closely related model designation. Most service components are shared across all three designations. 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 AFAIR10B36-B-1 including the Lennox capacitor parts, Lennox contactor parts, Lennox fan motor parts, and Lennox high-pressure switch parts.

AFAIR10B36-B-1: 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 AFAIR10B36-B-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 AFAIR10B36-B-1
Dual Run Capacitor for the AFAIR10B36-B-1
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.
AFAIR10B36-B-1 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 AFAIR10B36-B-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 AFAIR10B36-B-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.

AFAIR10B36-B-1 Parts FAQ
What is the AFAIR10B36-B-1 and what ton size is it?
The AFAIR10B36-B-1 is a three-ton R-22 residential outdoor condensing unit from Lennox’s Aire-Flo residential product line. The unit uses R-22 refrigerant requiring EPA 608 certified technicians for any refrigerant circuit service.
Why does my AFAIR10B36-B-1 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.
Are the Lennox AFAIR10B36-B-1, AFAIR10B36-B, and AC10B36-B parts interchangeable?
The AFAIR10B36-B-1 and AFAIR10B36-B are successive production revisions of the same three-ton Aire-Flo platform sharing most service components. The AC10B36-B is a closely related model designation. Always confirm the full model designation before ordering a replacement control board.
How often should I test the capacitor on the AFAIR10B36-B-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.
