Lochinvar & A.O. Smith 100233495 Inducer Motor

The Lochinvar & A.O. Smith 100233495 Inducer Motor is a critical combustion blower designed to maintain the precise negative pressure required for high-efficiency gas-fired systems. Pro-grade and cross-compatible, this assembly is a direct replacement for the FAN2402 and FAN2402K models. As a veteran-verified draft inducer motor, it ensures proper exhaust gas evacuation from the heat exchanger, preventing hazardous flue gas accumulation and ensuring the pressure switch closes to initiate the ignition sequence. This 120V centrifugal blower is engineered with high-temperature bearings to withstand the rigorous duty cycles of commercial boilers and residential water heaters. For technicians troubleshooting a furnace inducer motor failure, this unit serves as the OEM replacement motor needed to resolve rattling noises, seized bearings, or HVAC system lockouts. Its heavy-duty housing and balanced squirrel cage assembly are built to meet factory RPM specifications, ensuring consistent airflow and optimal combustion efficiency across a wide range of Lochinvar and A.O. Smith heating applications.

• Direct OEM Compatibility: Seamlessly replaces legacy part numbers FAN2402 and FAN2402K without structural modifications.
• Enhanced Safety: Reliably purges the combustion chamber of combustion byproducts, ensuring standard compliance and occupant safety.
• Durable Construction: Features high-grade steel and copper components designed for longevity in high-heat environments.
• Optimized Performance: Engineered for reduced vibration and noise, maintaining steady exhaust gas flow for consistent ignition cycles.

• Is this motor compatible with my specific boiler model? The 100233495 is a standard replacement for many Lochinvar Copper-Fin II and A.O. Smith commercial units. Verify your current motor's part number or check the unit's technical manual for FAN2402 or FAN2402K cross-references.
• Why is my inducer motor making a loud screeching sound? This typically points to worn-out bearings or a misaligned shaft. Replacing the full assembly is the most cost-effective solution to prevent a total system failure.
• Will this motor fix a 'pressure switch not closing' error? If the inducer motor is spinning below the required RPM or has a clogged housing, it cannot generate enough draft to close the switch. This OEM inducer motor is designed to restore factory-spec static pressure.
