Lochinvar & A.O. Smith 100110911 Blower Motor

The Lochinvar & A.O. Smith 100110911 Blower Motor is a high-performance OEM replacement component designed for commercial water heaters and high-efficiency boilers, including Lochinvar Knight and A.O. Smith BTH 400A/500A series units. Operating at 200V with a fixed speed of 6000 RPM, this centrifugal blower motor is engineered to meet precise combustion air requirements and maintain stable manifold pressure. As a critical part of the pre-purge and main burner cycles, the 100110911 ensures the correct air-to-fuel ratio for optimized thermal efficiency. Built with durable Fasco motor technology, this internal assembly handles the high-demand cycling typical of industrial HVACR heating plants. Reliable airflow circulation from this motor prevents blocked drain switches or air pressure switch faults, keeping heating systems operational under heavy load. Verify part number 100110911 against your unit's serial number for exact fitment compliance.

• OEM Compatibility: Precision engineered for Lochinvar and A.O. Smith commercial systems, ensuring seamless integration with existing control modules.
• High-Speed Efficiency: The 6000 RPM rating provides the necessary static pressure for consistent heat exchanger performance.
• Industrial Durability: Specifically designed to withstand the thermal stress of sealed combustion chambers.
• Performance Reliability: Eliminates common blower motor failure symptoms like bearing noise or intermittent ignition trial faults.

What are the signs of a failing 100110911 blower motor?
Technicians typically identify failure through excessive vibration, loud bearing squealing, or the boiler failing to initiate the pre-purge cycle, often resulting in an "Air Pressure Switch Not Closed" error on the display.

Is this motor compatible with 120V systems?
No, this specific part is rated for 200V applications. Installing this motor on a 120V circuit will lead to insufficient torque and potential motor burnout. Always check the nomenclature plate on the existing motor.

Does this assembly include the fan housing?
This part number refers to the blower motor assembly. Depending on the model, it may be supplied as a motor and impeller kit. Contractors should confirm if additional gaskets are required for air-tight combustion sealing.
