Lochinvar & A.O. Smith 100167774 Control Board
The Lochinvar & A.O. Smith 100167774 Control Board is a critical OEM replacement part designed specifically for the Lochinvar Knight XL KBN399 series heating boilers. As an integrated main control board, it manages the entire sequence of operation, from initial ignition control to flame sensing and blower motor timing. This board is engineered to interface seamlessly with commercial water heaters and high-efficiency boilers, ensuring precise water temperature management and system safety protocols. In the field, techs rely on this boiler control circuit board to resolve communication errors between the thermostat and the combustion system, particularly when dealing with KBN399 control board failures. By regulating the gas-fired water heater burner and safety procedures, this genuine 100167774 integrated control ensures the system operates at peak thermodynamic efficiency, reducing operational overhead and preventing premature component wear across the entire HVACR assembly.
Key Benefits:- Precise Ignition Management: Coordinates the ignition sequence and burner operation to ensure reliable startup in Knight XL heating boilers.
- Direct OEM Compatibility: Engineered as a drop-in replacement for Lochinvar and A.O. Smith systems, eliminating the mounting and wiring issues common with universal boards.
- Enhanced Safety Logic: Continuously monitors system sensors to prevent overheating and manages lockout procedures during flame failure.
- Optimized Energy Efficiency: Fine-tunes combustion timing and blower speeds to maximize fuel utilization in commercial water heating applications.
- What are the signs that my 100167774 control board needs replacement? Typical indicators include erratic LED diagnostic codes, the blower fan running constantly regardless of thermostat calls, or the burner shutting down immediately after ignition.
- Will this board work with the Knight XL KBN399? Yes, the 100167774 is the primary integrated control board specified for the KBN399 model and is essential for maintaining its modular firing rate.
- Is professional installation required for this part? Because this board controls high-voltage components and gas ignition sequences, installation should be performed by a licensed HVACR technician to ensure proper calibration and system safety.
