Lochinvar & A.O. Smith 100112328 Thermopile
The Lochinvar & A.O. Smith 100112328 Thermopile is a 25-inch, 750-millivolt generator engineered for high-performance gas water heaters utilizing Honeywell electronic gas controls. This OEM water heater part serves as the primary millivolt source for pilot-operated systems, ensuring reliable voltage to the gas valve electromagnet. Designed for compatibility with high-efficiency natural gas water heaters and propane units, it replaces standard thermocouple assemblies in models from Lochinvar, A.O. Smith, State, and Reliance. In technical field testing, this 750mV thermopile is rated for a maximum operating temperature of 750°C, providing a robust thermoelectric potential of ?750mV at 650°C. With an internal resistance of approximately 3.0?, it effectively resolves common ignition issues, such as a pilot light not staying lit or low status light voltage codes. For veteran technicians, this replacement heating element component ensures precise temperature regulation and long-term system stability in both residential and commercial FVIR applications.
Key Benefits- Universal Compatibility: Works across major brands including A.O. Smith, Lochinvar, Reliance, and Whirlpool with Honeywell valves.
- High Voltage Output: Delivers a consistent 750 millivolt signal to maintain proper gas valve operation and prevent nuisance shutdowns.
- Robust Build: Features a durable 25-inch lead with high-temperature insulation for use in demanding sealed combustion chambers.
- Direct OEM Fit: Ensures exact physical mounting and electrical connection, reducing labor time during water heater repair calls.
Is this thermopile compatible with FVIR-compliant water heaters?
Yes, the 100112328 is specifically designed for Flammable Vapor Ignition Resistant (FVIR) systems and is a standard replacement for many newer manifold burner assemblies.
How do I test if the thermopile is failing?
Using a multimeter set to millivolts, check the output at the gas valve connectors while the pilot is lit. If the reading is consistently below 350mV under load, the thermopile assembly likely requires replacement.
Will this work for both Natural Gas and Propane systems?
Yes, this component is material-compatible for use in both natural gas and liquid propane (LP) water heaters, provided the manifold assembly supports a 750mV system.
