Lochinvar & A.O. Smith 100111041 Controller
The Lochinvar & A.O. Smith 100111041 Combined Controller is the critical OEM replacement for BTH 250 100 high-efficiency commercial water heaters. As a veteran-grade HVAC control board, this unit integrates ignition control, temperature regulation, and diagnostic functions into a single combined controller module. It serves as a direct, high-performance successor to obsolete part number 9006265005. Designed for demanding commercial environments, this digital controller ensures precise modulation and consistent firing sequences, preventing common issues like short-cycling or intermittent lockouts. When performing a water heater controller replacement, this genuine OEM HVAC part provides the specific logic parameters required for the Cyclone BTH series, maintaining the high thermal efficiency ratings these units are known for. By restoring factory-spec communication between the sensors and the gas valve, technicians can ensure reliable operation and optimal heat transfer without the compatibility risks associated with generic aftermarket boards.
Key Benefits- Direct OEM Compatibility: Specifically engineered for Lochinvar BTH 250 100 and A.O. Smith Cyclone models, ensuring seamless plug-and-play installation with existing wiring harnesses.
- Enhanced Diagnostics: Features advanced internal logic to provide accurate error codes, reducing troubleshooting time during critical service calls.
- System Precision: Replaces the 9006265005 kit, offering improved relay durability and better resistance to electrical noise and voltage fluctuations.
- Integrated Logic: Manages both the ignition sequence and the operating setpoints to maximize combustion efficiency and reduce standby heat loss.
What are the symptoms of a failing 100111041 controller?
Technicians typically observe a blank display, the inducer motor failing to start, or the unit being stuck in a "waiting for ignition" loop despite having valid sensor inputs. A burnt smell or visible damage on the back of the PCB are also clear indicators for replacement.
How do I verify if this board is compatible with my BTH unit?
Confirm that your water heater is a BTH 250 100 model. This 100111041 controller is part-specific and should be verified against the serial number of the appliance to ensure the firmware matches the specific BTU rating and cabinet configuration.
Does this controller require a separate ignition module?
No, this is a combined controller, meaning it integrates the ignition control functionality with the temperature and operating control, simplifying the internal wiring of the water heater.
