Lochinvar & A.O. Smith 100074652 Wire
When the ignition sequence fails on a high-efficiency heater, the Lochinvar & A.O. Smith 100074652 Wire is often the critical link requiring inspection. This OEM flame rod wire is engineered to carry the low-level microamp DC signal from the flame sensor back to the integrated control board. In the field, we see these high-temperature leads fail due to flame rectification issues caused by heat-stiffened insulation or carbon tracking. This specific flame sensor lead is a direct replacement HVAC part for several Lochinvar and A.O. Smith boiler and water heater models, ensuring the flame rectification circuit maintains a stable 2 to 6 microamp signal. Technicians should verify that the 100074652 ignition wire is properly routed away from the burner plate to prevent thermal degradation of the jacket. As an authentic water heater repair part, it utilizes factory-spec connectors to eliminate high-resistance points that commonly trigger nuisance "no flame" lockouts on the job site.
Key Benefits- Ensures accurate flame rectification signal transmission to prevent system lockouts and nuisance trips.
- Constructed with high-grade insulation designed to withstand the ambient heat of burner compartments.
- OEM precision-fit connectors provide a secure, low-resistance interface between the sensor and module.
- Compatible with a wide range of Lochinvar, A.O. Smith, and Takagi commercial and residential units.
- Lightweight and flexible design allows for standard routing through existing internal wire harnesses.
How do I know if the flame rod wire is the cause of a lockout?
If you have a clean flame rod but still see 0.0 μA on your multimeter, check the continuity of the 100074652. High resistance or an open circuit in this lead often mimics a failed sensor or a bad board.
Can I use a standard 18AWG wire as a substitute?
No. Standard wiring may not have the thermal rating or specific impedance required for the flame rectification circuit. Using non-OEM leads can cause signal interference or premature insulation failure near the burner.
What is the proper way to test this wire in the field?
Set your meter to the microamp (μA) scale and connect it in series between the flame rod and this sensor wire. A healthy circuit should show a steady signal once the main burner ignites.
