The flame sensor monitors the burner flame signal and provides feedback to the control system, confirming ignition and enabling safe operation. Without a functioning flame sensor, the control board cannot verify combustion, causing the unit to shut down on lockout. This component is installed by licensed plumbers and HVAC technicians during routine maintenance or after a no-heat diagnostic call.\u003c\/p\u003e\n\u003cp\u003eThis flame sensor is suited for residential gas water heater applications where the OEM sensor has degraded, corroded, or failed to produce an adequate microamp signal. Flame sensors typically require replacement when the sensing rod is coated with oxide buildup that prevents accurate flame detection, resulting in nuisance lockouts or failure to light.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eOEM-style flame sensor rod for accurate flame signal detection\u003c\/li\u003e\n  \u003cli\u003eDirect replacement designed to restore proper burner operation and lockout prevention\u003c\/li\u003e\n  \u003cli\u003eCompatible with gas-fired appliance control systems that rely on microamp flame sensing\u003c\/li\u003e\n  \u003cli\u003eDurable construction suited for high-temperature burner environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement flame sensor for AO SMITH gas-fired water heaters and related heating appliances.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified HVAC technician. Shut off gas supply and disconnect power to the appliance before servicing any burner components. The sensing rod must be positioned correctly within the burner flame path to achieve an adequate microamp reading. Follow all applicable local codes and the manufacturer service documentation when replacing burner components.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: Flame Sensor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AO SMITH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 100112678\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TAILWIND","offers":[{"title":"Default Title","offer_id":51149780255026,"sku":"100112678","price":51.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305989934.jpg?v=1778601259","url":"https:\/\/voomisupply.com\/products\/ao-smith-100112678-flame-sensor-1","provider":"Voomi Supply","version":"1.0","type":"link"}
