Lochinvar & A.O. Smith 100318923 Motor
When you're dealing with a residential or commercial boiler call, a stuck or failed damper is a common culprit for system lockouts and poor combustion efficiency. This Lochinvar & A.O. Smith 100318923 Motor is a genuine 24v Damper Motor designed to provide precise actuation for air intake and exhaust dampers. As a critical component in the combustion assembly, this motor ensures the correct airflow regulation by physically opening and closing the damper blade based on the signal from the integrated control board. Operating on a standard 24VAC control circuit, it is a versatile replacement part compatible with a wide range of Lochinvar boilers and A.O. Smith water heaters. Its 1.66 lb weight and compact form factor allow for straightforward mounting in tight cabinet spaces, ensuring a direct fit for OEM 100318923 replacements without the need for field modifications or bracket fabrication.
Key Benefits for Technicians:
- Direct OEM Replacement: Replaces factory-installed 100318923 motors in Lochinvar and A.O. Smith units, ensuring full electrical and mechanical compatibility with existing 24v wiring harnesses.
- Enhanced Combustion Efficiency: Prevents standby heat loss and optimizes the air-to-fuel ratio by maintaining strict control over the damper position during the pre-purge and post-purge cycles.
- Proven Durability: Engineered to withstand the high-temperature environments typical of boiler jackets, reducing callbacks related to early motor burnouts or gear stripping.
- Simplified Installation: Standard voltage requirements and mounting points allow for a quick "drop-in" swap, getting your customer's heating system back online faster.
- System Reliability: Restores dependable automatic damper control, preventing the nuisance trips and safety lockouts caused by slow or intermittent actuator response.
Common Questions:
What are the symptoms of a failing Lochinvar damper motor?
Technicians typically observe a 'damper failed to open' error code on the control interface or find the system hanging in the pre-purge stage with no ignition, often caused by the 24v damper actuator failing to reach its end-stop.
Can I use this motor on a 120V circuit?
No, this is a dedicated 24v HVAC motor. Applying line voltage will result in immediate component failure. Always verify control transformer output before installation.
Does this motor include the end-switch?
The 100318923 is designed to interface with the unit’s specific control sequence to verify position; always check your specific wiring diagram to ensure the internal or external proving circuit is satisfied after replacement.
