Lochinvar & A.O. Smith 100074228 Motor
The Lochinvar & A.O. Smith 100074228 Fan Motor is a critical OEM component engineered for high-efficiency condensing tankless water heaters and specific boiler models. As a veteran-grade HVAC replacement motor, it is designed to manage the precise air-to-fuel ratio required for optimal combustion. This centrifugal fan motor facilitates the consistent circulation of air and exhaust gases, ensuring the ventilation system operates within manufacturer parameters to prevent overheating and premature heat exchanger fatigue. Built for continuous operation, this blower motor assembly is a direct replacement for A.O. Smith tankless parts, specifically compatible with T-H3, ATI, GTS, and GT series units. Integrating a genuine 100074228 motor kit restores system pressure balances and eliminates common low air flow errors often associated with bearing wear or electrical failure in aging induction fans. By maintaining stable RPMs, it ensures high-performance thermal regulation and long-term reliability in demanding residential and commercial hydronic applications.
Key Benefits- Ensures precise combustion air delivery for high-efficiency condensing units.
- Direct OEM replacement for seamless fitment in Lochinvar and A.O. Smith platforms.
- Reduces the risk of exhaust gas recirculation and combustion instability.
- Robust construction designed for continuous duty cycles in diverse environments.
- Optimizes thermal regulation to protect the primary heat exchanger from hot spots.
What are the signs that my Lochinvar 100074228 motor is failing?
Technicians typically identify failure through audible bearing noise (vibration), a "low air" fault code on the interface, or if the motor housing is hot to the touch while the fan remains stationary.
Is this motor compatible with the T-H3 series tankless heaters?
Yes, this specific part number is the verified OEM replacement for the T-H3, T-H3S, T-H3J, and T-H3M models, as well as several condensing series from State and American Water Heaters.
Does this kit include the necessary gaskets for installation?
This is the fan motor assembly; for a full combustion service, technicians often recommend inspecting the Venturi gaskets and igniter O-rings to ensure a complete airtight seal during replacement.
