Lochinvar & A.O. Smith 100210100 Blower Assembly

When you are troubleshooting a BE-1 No Blower Feedback fault code on a high-efficiency water heater, replacing the Lochinvar & A.O. Smith 100210100 Blower Assembly is often the necessary path to restoring full system functionality. This OEM blower assembly is a critical safety and performance component designed for power vent (PV) and radial fire burner systems in Lochinvar and A.O. Smith units. Rated for up to 165-degree operation, this RBC PV blower ensures the correct draft for efficient combustion and the safe elimination of flue gases. As a veteran tech knows, maintaining precise variable speed blower control via the 5-pin PWM signal socket is non-negotiable to prevent Btu/hr input spikes that could damage the heat exchanger. This assembly is built for HVAC residential and commercial durability, featuring heavy-duty construction that minimizes vibration and emissions. When installing, verify the blower flange gasket integrity and torque mounting screws to no more than 40 inch-lbs to avoid deforming the seal.

• Direct OEM Compatibility: Ensures an exact fit and electrical integration for A.O. Smith Cyclone Mxi and Lochinvar BTH series units.
• High-Temperature Resilience: Engineered to handle 165°F discharge temperatures common in high-recovery heating applications.
• Enhanced Combustion Efficiency: Provides stable airflow to the radial fire burner, reducing the risk of rough operation or ignition failure.
• Integrated Safety: Designed to work seamlessly with the blower prover air pressure switch for reliable safety circuit monitoring.

Common Questions

What does the BE-1 error code mean in relation to this part?
The BE-1 code indicates that the controller is not receiving a speed feedback signal from the blower. This is usually caused by a failed motor control board within the assembly or a disconnected PWM signal plug.

Can I use this blower to replace a different temperature-rated assembly?
No. This unit is specifically calibrated for systems requiring a 165-degree blower assy. Using a lower-rated part can lead to premature failure and safety hazards due to heat exposure.

Do I need to replace the gasket when installing this new blower?
While some gaskets can be reused if they show no signs of compression set or tearing, it is standard professional practice to install a new flange gasket to ensure a gas-tight seal at the blower adapter.
