Lochinvar & A.O. Smith 100309395 Assembly
The Lochinvar & A.O. Smith 100309395 Assembly is a vital Universal ES Module Assembly engineered for precision ignition control and burner management in high-efficiency gas-fired systems. Designed as a direct OEM replacement part, this module facilitates seamless communication between the thermostat and the combustion assembly, ensuring safe and reliable water heater operation. As a veteran in the field, you know that HVAC control board troubleshooting starts with reliable hardware; this assembly effectively replaces legacy part numbers 100263931 and 6911176, providing broad HVAC part compatibility across a wide range of commercial and residential models. The integrated circuitry monitors temperature settings and manages the safety limit circuit to prevent short cycling and intermittent breakdowns. For contractors performing a water heater module replacement, this rugged component ensures stable flame rectification and consistent system diagnostic performance. Its universal design reduces truck stock requirements while maintaining the high factory standards required for modern hydronic and domestic hot water applications.
Key Benefits- Universal Compatibility: Serves as a direct-fit replacement for multiple A.O. Smith and Lochinvar models, streamlining your inventory management.
- Enhanced Safety Logic: Continuously monitors gas-fired burner states to ensure active flame sensing and immediate shutdown during fault conditions.
- Optimized Efficiency: Precision control over combustion cycles reduces fuel waste and extends the service life of the primary heat exchanger.
- Rugged OEM Build: Manufactured to strict factory specifications to withstand the high-temperature environments typical of commercial mechanical rooms.
- Which models does this part fit? This assembly is primarily used in gas-fired water heaters and boilers; it specifically replaces legacy part numbers 100263931 and 6911176.
- Does this module include a diagnostic display? It integrates with the system's existing interface to provide error codes and operational status for faster field diagnostics.
- Is professional installation required? Yes, due to its role in ignition control and gas valve management, it should only be installed by a licensed HVAC technician.
