The thermistor feeds real-time temperature data to the control board, which uses that signal to regulate burner output and maintain consistent delivery temperatures. The kit includes an O-ring, mounting bracket, and screw, giving technicians everything needed for a complete sensor replacement in a single package. This is an OEM-specified component designed for accurate, reliable performance in the demanding thermal environment of a tankless gas appliance.\u003c\/p\u003e\u003cp\u003eThis thermistor kit is intended for use in Rheem tankless gas water heater systems where the outlet temperature sensor has failed, drifted out of calibration, or been damaged. A faulty outlet thermistor commonly causes error codes, erratic temperature output, or burner lockout conditions. Replacing the sensor restores proper closed-loop temperature control and allows the unit to resume normal operation. Installation is typically performed by a licensed plumber or HVAC technician during a service call on a residential or light-commercial Rheem tankless unit.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSenses hot water temperature at the heat exchanger outlet for accurate burner modulation\u003c\/li\u003e\n\u003cli\u003eFeeds real-time data to the control board to maintain consistent delivery temperature\u003c\/li\u003e\n\u003cli\u003eKit includes O-ring, mounting bracket, and screw for a complete replacement\u003c\/li\u003e\n\u003cli\u003eOEM part number ensures proper fit and calibration within Rheem control systems\u003c\/li\u003e\n\u003cli\u003eAddresses common fault codes and erratic temperature symptoms caused by sensor failure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement outlet thermistor for Rheem tankless gas water heater systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified service technician. Shut off the cold water supply and disconnect power or gas to the unit before beginning sensor removal. Allow the heat exchanger to cool completely before handling the thermistor or O-ring to avoid burns. Ensure the O-ring is seated correctly and the bracket screw is snug before restoring power and testing for proper temperature response.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type\u003c\/strong\u003e: Water Heater Parts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSub Type\u003c\/strong\u003e: Outlet Thermistor Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKit Contents\u003c\/strong\u003e: Thermistor, O-ring, bracket, screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RHEEM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: rtg20319r\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RHEEM","offers":[{"title":"Default Title","offer_id":51672652022066,"sku":"RTG20319R","price":22.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6be8fae3b164a71c4860e594b47735b.jpg?v=1787970342","url":"https:\/\/voomisupply.com\/products\/rheem-rtg20319r-outlet-thermistor-kit","provider":"Voomi Supply","version":"1.0","type":"link"}
