Lochinvar & A.O. Smith 100167795 Control

The Lochinvar & A.O. Smith 100167795 Control is a critical integrated control board engineered specifically for high-efficiency hydronic systems. This OEM component is the primary interface for Knight XL boiler models KBN601 through KBN801 with serial numbers prior to H10. As a veteran-grade replacement control module, it manages the entire firing sequence, including direct spark ignition, flame sensing via the flame sensor circuit, and precise modulation of the combustion blower. By consolidating multiple safety and operational functions into a single HVAC integrated circuit board, this unit ensures optimized heat exchanger performance and energy-efficient cycling.

When performing a Lochinvar boiler repair, this 100167795 control board is essential for resolving communication errors between the UIM (User Interface Module) and the main boiler logic. It features a technical design that supports advanced HVAC diagnostics, allowing contractors to monitor fault history and current system status. Its robust architecture is built to handle the demanding electrical loads of commercial and residential heating environments, ensuring your Knight XL KBN series unit maintains peak operational reliability through accurate temperature sensing and safety limit monitoring.

• Broad Compatibility: Drop-in replacement for Knight XL models KBN601, KBN701, and KBN801 (S/N prior to H10).
• Integrated Logic: Consolidates ignition control, blower speed modulation, and safety circuit monitoring into one OEM control assembly.
• Advanced Diagnostics: Facilitates troubleshooting by providing detailed error code feedback when paired with the system display.
• High Precision: Optimizes hydronic heating cycles to reduce fuel consumption and prevent unnecessary component wear.

• Which boiler models are compatible with the 100167795 control? This part is specifically designed for Lochinvar Knight XL models KBN601 to KBN801, provided the unit's serial number is prior to H10.
• Does this board control the blower motor? Yes, this integrated control manages the combustion fan speed to ensure the correct air-to-gas ratio across all modulation firing rates.
• Can I use this board for a standard Knight KBN501? No, while similar in appearance, the 100167795 is calibrated for the larger 601-801 inputs; you must verify your specific model and serial range to ensure proper logic mapping.
