Lochinvar & A.O. Smith 100137144 Fan Assembly

The Lochinvar & A.O. Smith 100137144 Inducer Fan Assembly is a mission-critical 115V component engineered for precise combustion air delivery in high-efficiency systems. As a direct OEM replacement for FAN2410 and FAN2410K, this assembly is purpose-built for Lochinvar Knight boilers (models 150-400), Noble combi units, and select A.O. Smith residential pool heaters. For contractors troubleshooting "no ignition" or "low airflow" faults, this 3,450 RPM motor provides the necessary static pressure to clear the venting system and ensure safe combustion cycles.

Constructed with a permanent split capacitor motor, this 115V inducer fan is designed to handle the corrosive environment of condensing exhaust gases without premature bearing failure. When replacing a Knight boiler fan assembly, verifying the 100137144 part number ensures full compatibility with existing control modules and wiring harnesses. This heavy-duty draft inducer is essential for maintaining strict air-to-fuel ratios, preventing heat exchanger overheating, and ensuring the long-term reliability of the burner assembly.

Key Benefit List:

• Direct OEM Integration: Operates as the official successor to FAN2410 and FAN2410K, requiring no field modifications to the mounting bracket.
• High-Performance 115V Motor: Delivers consistent 3,450 RPM to maintain calibrated pressure across the flue sensor and pressure switches.
• Durable Combustion Flow: Specifically designed for Knight and Noble series boilers to manage exhaust cycles and prevent moisture-related stall.
• Enhanced Reliability: Heavy-duty construction minimizes vibration and noise, common precursors to system-wide lockouts in Lochinvar heating systems.

Common Questions & Troubleshooting:

Is this compatible with my older Lochinvar model?
Yes, if your service manual calls for FAN2410 or FAN2410K, this 100137144 assembly is the current manufacturer-spec replacement for your 150-400 series unit.

Does this unit include the required gaskets?
While the assembly includes the primary inducer motor and housing, it is industry standard to inspect the flue sensor gasket and blower seals during installation as these often degrade alongside the motor.

How do I fix a squealing noise in my Lochinvar blower?
A high-pitched squeal usually indicates bearing wear. Replacing the assembly with a genuine 100137144 fan prevents the fan blades from eventually contacting the housing, which can lead to expensive control board damage.
