The Lochinvar & A.O. Smith 100307609 is an OEM replacement flame sensor kit designed to maintain safe and reliable burner operation in compatible Lochinvar and A.O. Smith water heaters and boilers. The flame sensor detects the presence of a burner flame and sends a signal to the control board — if no flame is detected, the control system safely shuts off the gas supply to prevent hazardous conditions.
This kit includes the flame sensor rod, a replacement gasket for a leak-free seal, and the necessary mounting screws, making it a complete drop-in solution that simplifies the service call and eliminates the need to source individual components separately.
