This kit includes the components needed to replace or install a SA-10K thermistor-based sensing element in 2 to 4 channel configurations. The thermistor provides the control board with real-time temperature data, enabling precise regulation of heating cycles. Installation is typically performed by licensed plumbers or water heater service technicians during routine maintenance or component failure diagnosis.\u003c\/p\u003e\u003cp\u003eThis sensor assembly is suited for residential and light commercial water heating applications where multi-channel temperature sensing is required. The 2 to 4 channel design allows the kit to serve systems that monitor multiple zones or positions within the water heater, such as inlet, outlet, or tank body locations. Technicians replacing a failed thermistor or upgrading sensor coverage will find this kit provides the necessary hardware for a complete assembly replacement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSA-10K thermistor sensing element for accurate temperature detection\u003c\/li\u003e\n\u003cli\u003eSupports 2 to 4 channel temperature monitoring configurations\u003c\/li\u003e\n\u003cli\u003eComplete assembly kit includes all components needed for replacement\u003c\/li\u003e\n\u003cli\u003eDesigned for integration with compatible AO SMITH water heater control systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement temperature sensor assembly for AO SMITH water heating systems utilizing SA-10K thermistor-based multi-channel control configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified water heater service technician. Always shut off power to the water heater at the breaker and allow the unit to cool before handling internal sensor components. Follow local plumbing codes and the manufacturer service documentation when routing and connecting sensor leads to the control board. Do not overtighten sensor fittings or force connectors into place.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensor Type\u003c\/strong\u003e: SA-10K Thermistor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChannel Configuration\u003c\/strong\u003e: 2 to 4 Channel\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 100291049\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TAILWIND","offers":[{"title":"Default Title","offer_id":51150232518962,"sku":"100291049","price":35.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305990180.jpg?v=1778608178","url":"https:\/\/voomisupply.com\/products\/ao-smith-100291049-temp-sensor-assembly-kit","provider":"Voomi Supply","version":"1.0","type":"link"}
