The Carrier LA01RA220 is a direct-replacement condenser fan blade engineered to restore proper airflow through the outdoor condensing unit on Carrier, Bryant, and Payne residential and light-commercial air conditioners. With a 20 in. swept diameter, 20 degree blade pitch, and clockwise rotation, this blade moves adequate condenser airflow to keep your system running at rated efficiency -- without the vibration and noise that come from a cracked or unbalanced OEM blade.
A damaged or deteriorated condenser fan blade is one of the most common causes of high-head-pressure trips, reduced cooling capacity, and compressor stress during peak summer demand. The LA01RA220 replaces the original blade with the exact geometry -- diameter, pitch, bore, and rotation -- that Carrier specified for the unit, so airflow volume and direction are restored to factory design intent.
This blade is also catalogued under NBK Parts number 20484, making it easy to cross-reference across HVAC supply channels. Its lightweight polypropylene construction keeps motor starting load low while resisting the UV exposure and humidity cycles that cause older blades to warp or crack over time.
Matches factory 20 in. diameter and 20 degree pitch for correct airflow volume and direction on Carrier, Bryant, and Payne condensing units.
1/2 in. bore fits the standard condenser motor shaft used across a wide range of Carrier-family outdoor units -- no adapters or machining needed.
Clockwise rotation (viewed from the motor side) pulls air through the condenser coil in the correct direction to maintain rated heat rejection.
At 0.5 lbs., the blade minimizes starting torque demand on the condenser motor and reduces vibration for quieter, longer-lasting operation.
The LA01RA220 was sourced by Carrier for use across multiple product lines sold under the Carrier, Bryant, and Payne brand names -- all of which share the same parent engineering and component specifications. If your existing condenser fan blade shows a 20 in. diameter, 20 degree pitch, 1/2 in. bore, and clockwise rotation stamp or label, the LA01RA220 is the correct replacement regardless of which brand nameplate is on the cabinet.
The condenser fan blade is under constant UV exposure, thermal cycling, and mechanical stress from repeated motor starts. Over time, blades can develop stress cracks near the hub, warp enough to change effective pitch, or lose a tip -- any of which disrupts airflow and forces the compressor to work harder. Replacing a worn or damaged blade promptly protects the compressor and keeps the system operating within its design efficiency range.
Replacing the condenser fan blade is a straightforward service task on most Carrier-family units:
