Trane FAN3842 Fan Blade

For high-demand condenser replacements, the Trane FAN3842 (also identified as FAN03842) is the standard 26-inch aluminum OEM replacement fan blade designed for heavy-duty HVACR applications. This 3-blade assembly features a 30-degree pitch and a 1/2-inch bore diameter, specifically engineered to maintain the precise condenser fan airflow required by Trane and American Standard rooftop units and split systems. Replacing a warped or unbalanced blade with this authentic Trane HVAC part is critical for preventing vibration-induced motor bearing failure and ensuring optimal heat transfer across the condensing coils.

Constructed from high-grade aluminum, this propeller is built for corrosion resistance and long-term HVAC system reliability. It provides a direct fit for numerous TCD and YCD series 20-ton to 120-ton commercial units, where maintaining specific static pressure and CFM is non-negotiable. As a veteran-grade air conditioner fan blade replacement, it secures directly to the motor shaft via a robust hub mount, eliminating the need for field modifications and restoring factory-spec performance immediately upon installation.

• Precise OEM Specification: Features a 26-inch diameter and 30-degree pitch to meet exact Trane FAN3842 propeller requirements for static pressure.
• Durable Aluminum Construction: Lightweight yet rigid 3-blade design reduces start-up torque on the condenser fan motor.
• Standardized Fit: 1/2-inch hub bore ensures compatibility with standard HVAC motor shafts across commercial product lines.
• Optimized Cooling: Engineered CW rotation (Clockwise) pulls air efficiently through the coil to maximize compressor longevity.

Is the Trane FAN3842 compatible with American Standard units?
Yes, as an OEM part for the Trane family, this blade is frequently utilized in cross-branded American Standard commercial condensing units that share the same cabinet and motor specifications.

What are the signs that I need a new condenser fan blade?
Technicians should look for excessive unit vibration, visible stress cracks at the hub, or "banging" noises from the outdoor cabinet, which typically indicate an out-of-balance or bent blade assembly.

Does this blade include the set screw for the motor shaft?
Yes, this hub-mounted blade includes the necessary hardware to secure the 1/2-inch bore to the keyed or flat-sided motor shaft for a slippage-free connection.
