This critical safety component is responsible for detecting the presence of a flame once the gas valve opens. By sending a microamp signal back to the furnace control board, it confirms that ignition was successful, preventing the system from pumping unburned gas into your home.\u003c\/p\u003e\n\u003cp\u003eEngineered for durability in high-heat environments, this sensor features a high-grade Alumina ceramic insulator and a specialized metal alloy rod capable of withstanding constant exposure to temperatures exceeding 1800°F. The \u003cstrong\u003e90-degree bend\u003c\/strong\u003e is specifically designed to position the sensing rod directly in the path of the burner flame for rapid and accurate flame rectification. Choosing a genuine S1-2702-311P ensures the correct mounting alignment and electrical resistance required by your specific York control board.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eKey Features and Function:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRapid Flame Detection:\u003c\/strong\u003e Optimized rod geometry ensures the control board receives a steady microamp signal within seconds of ignition.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003e90° Offset Design:\u003c\/strong\u003e Precision-bent to provide an exact \"reach\" into the flame header for specific York and Coleman burner assemblies.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eHigh-Temperature Ceramic Base:\u003c\/strong\u003e Prevents electrical leakage to the ground, ensuring the signal is not lost or \"ghosted\" by moisture or heat stress.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eDirect-Fit OEM Quality:\u003c\/strong\u003e Eliminates the need for bending or modifying universal sensors, which can lead to brittle rod failure.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eProduct Details and Key Specifications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePart Number:\u003c\/strong\u003e S1-2702-311P (Replaces 2702-311, S1-02530777000)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eManufacturer:\u003c\/strong\u003e York \/ Johnson Controls (Genuine OEM)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003ePart Type:\u003c\/strong\u003e Flame Sensor Rod\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eRod Shape:\u003c\/strong\u003e 90° Degree Bend\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eConnection:\u003c\/strong\u003e 1\/4\" Male Quick-Connect Terminal\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eInsulator Material:\u003c\/strong\u003e Alumina Ceramic\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eMounting:\u003c\/strong\u003e Single-hole screw flange\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003e🛠️ HVAC Depot Pro Tip: The \"Steel Wool\" Secret\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eFlame sensors are the #1 cause of \"3-Flash\" or \"Ignition Failure\" codes. Before replacing, you can often restore function by lightly cleaning the rod with a piece of fine steel wool or a Scotch-Brite pad to remove carbon buildup. However, if the ceramic insulator has a hairline crack, the sensor must be replaced, as electricity will \"leak\" to the furnace frame and cause intermittent lockouts.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eCross-Reference \u0026amp; Compatibility:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eThe S1-2702-311P is a direct replacement for the following part numbers:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eYork\/JCI Numbers:\u003c\/strong\u003e 2702-311, 2702-311P, 025-30777-000, S1-02530777000\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eSource 1:\u003c\/strong\u003e S1-2702-311P\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e\u003cstrong\u003eExtensive Model Compatibility List:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eYork Affinity \u0026amp; Latitude Series:\u003c\/strong\u003e TG8S, TG9S, TM8T, TM9T, TM9V, TMLV\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cstrong\u003eColeman \/ Luxaire:\u003c\/strong\u003e Fits various high-efficiency and standard-efficiency models including TG, TM, and G8\/G9 series.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"York","offers":[{"title":"Default Title","offer_id":52612031054187,"sku":"S1-2702-311P","price":52.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/S1-2702-311P.jpg?v=1764021551","url":"https:\/\/tophvacparts.com\/products\/york-s1-2702-311p-genuine-oem-furnace-flame-sensor-90-bend","provider":"HVAC Parts and Equipment Depot","version":"1.0","type":"link"}
