Carrier LA660003 Fan

The Carrier LA660003 Inducer Cooling Fan is a critical OEM replacement part designed for high-efficiency furnace draft inducer motor assemblies. This cooling fan blade is the direct performance alternative for the discontinued 326100-401, engineered to provide essential thermal management for the inducer motor during high-load combustion cycles. Constructed from durable, heat-resistant materials, the LA660003 maintains a precise 3-1/4 inch diameter and 15/16 inch height to ensure proper clearance within the housing. It features a 5/16 inch bore compatible with single side flat shafts, utilizing a counter-clockwise (CCW) rotation from the hub end. By facilitating consistent airflow and heat dissipation, this fan protects the motor windings from premature failure, ensuring the exhaust system effectively vents combustion gases. A metal retaining clip (AS31XH280) is typically required for a secure press-fit installation onto the motor shaft to prevent vibration-induced slippage.

• Precise OEM Fit: Direct replacement for 326100-401, ensuring zero-clearance issues in Carrier, Bryant, and Payne units.
• Thermal Protection: Optimized blade pitch for maximum inducer motor cooling, extending the service life of the draft assembly.
• High-Temperature Durability: Engineered for high-efficiency furnace environments where consistent heat cycles are standard.
• Quiet Operation: Balanced fan wheel design minimizes mechanical noise and vibration during the ignition sequence.

• Will this fan fit my 5/16" motor shaft? Yes, the LA660003 is specifically bored for 5/16" single flat shafts used in most residential inducer motors.
• Does this part include the metal retaining clip? This listing is for the fan blade; verify if your existing AS31XH280 clip is salvageable or if a new one is required for the install.
• Can I use this if my old fan is 326100-401? Absolutely. The LA660003 is the official factory-authorized successor to the 326100-401.
