Lochinvar & A.O. Smith 100167824 Control Board
The Lochinvar & A.O. Smith 100167824 Control Board is a critical integrated component designed for high-efficiency Knight XL heating boilers, specifically the KBN501 series. As a direct replacement for the obsolete RLY30066, this OEM control board manages essential system parameters including hot surface ignition, flame sensing, and temperature regulation. It ensures precise HVAC system timing and safety protocols by monitoring the air pressure switch and blower assembly feedback loops to prevent short-cycling and operational failures.
Engineered for technical reliability, the 100167824 features an onboard microprocessor that generates user-friendly diagnostics for rapid troubleshooting in the field. This board is polarity sensitive and requires a verified 120 VAC ground to function correctly. By accurately regulating gas valve signals and modulation rates, this integrated controller optimizes thermal efficiency for both residential and light commercial heating applications, maintaining stable performance in demanding boiler repair scenarios.
Key Benefits- Direct OEM Replacement: Seamlessly replaces obsolete RLY30066 models in Knight XL systems without field modifications.
- Advanced Diagnostics: Simplifies troubleshooting with real-time error code reporting for sensors and ignition components.
- Integrated Safety Logic: Continuously monitors flame current and exhaust venting to ensure fail-safe operation.
- Optimized Efficiency: Precision control over the combustion process minimizes fuel waste and stabilizes heat output.
Is this board compatible with all Knight boiler models?
This specific board is engineered for the Knight XL KBN501 series (beginning with serial H10). Always verify your boiler's serial number and current control board part number before installation.
What does an "AC Reversed" error mean on this board?
This indicates that the 120 VAC power supply polarity is reversed. The board is sensitive to wiring orientation and requires the "hot" and "neutral" wires to be correctly terminated for the flame sensor to establish a circuit.
Does this part involve the ignition sequence?
Yes, it manages the entire startup sequence, including the blower pre-purge, igniter energization, and flame rectification check to ensure the burner remains lit safely.
