Lochinvar & A.O. Smith 100110833 Blower

The Lochinvar & A.O. Smith 100110833 Blower is a critical EPC Blower & Motor Outline Assembly engineered for high-efficiency commercial and residential combustion systems. As a direct OEM replacement part, this 10.92-pound unit provides the precise pulse width modulation (PWM) blower control required for advanced fuel-to-air mixing in Lochinvar boilers and A.O. Smith water heaters. Designed for reliability in demanding heating cycles, the assembly facilitates optimal airflow to ensure your condensing boiler maintains its 96% or higher thermal efficiency rating. For technicians, this 100110833 motor assembly is the standard for restoring factory-spec combustion in models ranging from the Knight series to high-output water heating units. By utilizing a high-torque motor integrated with a durable blower housing, this replacement induction blower minimizes vibration and prevents the common pressure switch errors associated with failing fan assemblies in HVAC systems.

• Optimized Combustion: Precision-balanced impeller ensures consistent air-fuel ratios, critical for high-efficiency modulation.
• Drop-in Compatibility: Genuine OEM construction guarantees a perfect fit, eliminating the need for field modifications.
• Reduced Downtime: Robust motor bearings and rugged housing are built for the high-cycle demands of commercial potable water and hydronic applications.
• Performance Signal: Integrated PWM control allows the system controller to move from low-fire to high-fire with pinpoint accuracy.

What are the symptoms of a failing 100110833 blower?
Technicians typically identify failure through increased mechanical noise (bearing wear), frequent combustion lockouts, or "Low Air" error codes on the unit's control board.

Is this assembly compatible with both Natural Gas and Propane units?
Yes, this blower assembly is used across various fuel types as it manages air intake prior to the gas valve's negative pressure regulation, though you should always verify the specific model's firing rate.

Does this include the mounting gasket?
While the 100110833 is a complete motor and blower outline assembly, it is best practice to inspect the existing blower gasket and replace it if any compression set or tearing is visible to maintain a sealed combustion chamber.
