Lochinvar & A.O. Smith 100167817 Ignition Module

The Lochinvar & A.O. Smith 100167817 Ignition Module is a critical OEM replacement for RLY3006 and S8610H30-18, engineered to handle sequence control in high-efficiency gas-fired appliances. This 24V intermittent pilot ignition control manages the gas valve, detects flame presence, and provides safety shutoff for residential and commercial heating systems. Operating at 24 VAC (50/60Hz) with a 150mA current draw, it is the direct factory-authorized solution for maintaining the combustion analysis parameters of Lochinvar Knight and CWN series boilers. As a HVAC technician, you know that intermittent flame failure ignition lockouts often trace back to a failing module failing to prove the flame signal. This robust electronic component replaces legacy models like the RLY2017, providing consistent spark generation and lead-lag timing. Ensure proper electrical grounding of the unit and check for negative pressure at the gas valve during your boiler troubleshooting to confirm this burner control is the necessary fix for site-specific lockout codes.

• Direct OEM Match: Provides an identical fit and function for 100167817 and RLY3006, ensuring no onsite field modifications are required.
• Universal Compatibility: Widely utilized in Lochinvar Power-Fin, Knight, and A.O. Smith commercial water heaters.
• Enhanced Safety: High-precision internal circuitry prevents gas buildup by adhering to intermittent pilot ignition safety protocols.
• Contractor Grade: Built with advanced electronic components to withstand the high-temperature environments of boiler cabinets.

• What does a "Flame Fail Ignition" code mean on a Lochinvar boiler? This usually indicates the 100167817 module or the flame rod is not sensing a pilot flame. If the spark electrode is firing but the main burner won't engage, the ignition module is likely failing to send the signal to the gas valve.
• Is the 100167817 equivalent to the RLY3006? Yes, these part numbers are interchangeable. The 100167817 is the current manufacturer part number for the older RLY3006 ignition control.
• Does this module work with 24V systems? Yes, it is specifically designed for 24 VAC circuits. Always verify input voltage at the transformer before installing to avoid damaging the new control board.
