Lochinvar & A.O. Smith 100093838 Gas Valve

The Lochinvar & A.O. Smith 100093838 Gas Valve is a critical OEM replacement part designed for precision fuel regulation in high-efficiency water heaters and boilers. Engineered with a 1/2" connection size, this dual-fuel component is factory-calibrated for both Natural Gas (NAT) and Liquid Propane (LP) applications, ensuring versatile field integration. As a redundant gas valve, it incorporates internal safety shut-offs to maintain a secure seal when the controller terminates the 24V signal. Its robust construction is specifically tailored for Lochinvar Knight and A.O. Smith residential units, providing the consistent manifold pressure required to prevent ignition failure or flame rollout. For technicians performing HVAC troubleshooting, this valve facilitates accurate gas pressure regulation and is a direct substitute for legacy part number 9000796005, restoring the appliance to original manufacturer specifications for combustion efficiency and thermal performance.

• Dual-Fuel Compatibility: Engineered for seamless operation with Natural Gas and LP systems.
• OEM Reliability: Genuine Lochinvar and A.O. Smith component ensures exact fitment and 1/2" NPT thread alignment.
• Safety Instrumentation: Features redundant solenoid seats to prevent hazardous gas bypass during standby cycles.
• Standardized Voltage: Operates on standard 24V AC control circuits for broad compatibility with modern electronic ignition modules.

• Does this valve come with LP conversion hardware? This model is built for NAT/LP versatility; always verify the manifold pressure settings with a manometer during installation to match your specific fuel source requirement.
• How do I diagnose a faulty 100093838 valve? Often, an ignition lockout or "No Flame" error occurs. Confirm 24V is reaching the terminals; if power is present but the valve fails to open, a replacement is necessary.
• Is this compatible with older 9000796005 models? Yes, the 100093838 is the official replacement gas valve for the discontinued 9000796005 part number.
