The flame sensor monitors combustion activity within the burner assembly, sending a signal to the control board to confirm that ignition has occurred and that the burner is operating safely. If the sensor fails to detect a flame, the control board shuts down the burner to prevent unburned gas accumulation. This part is installed by licensed plumbers and HVAC technicians performing diagnostics or preventive maintenance on water heating equipment.\u003c\/p\u003e\u003cp\u003eThis flame sensor is a direct replacement component for the AO SMITH Legend 1000 water heater platform. It is appropriate for residential or light commercial service calls where the original sensor has failed, corroded, or produced nuisance lockout faults. Technicians typically replace this part when the unit cycles off on flame-loss fault codes despite confirmed ignition, indicating a weak or failed sensor signal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eOEM-style replacement flame sensor for the Legend 1000 platform\u003c\/li\u003e\n\u003cli\u003eRestores proper flame detection and burner safety shutoff function\u003c\/li\u003e\n\u003cli\u003eDirect drop-in fit eliminates need for field modification\u003c\/li\u003e\n\u003cli\u003eDesigned to work with the existing control board and ignition circuit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement flame sensor for the AO SMITH Legend 1000 water heater.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified HVAC technician.
