Before replacing the T6-2108, try cleaning the existing rod with a light scrub using fine steel wool or an emery cloth. This often restores the sensor's ability to detect the micro-amp current of the flame, potentially saving a service call or the cost of a new part. \u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eThe 17J56 is a direct OEM replacement for the following part numbers:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eOEM Numbers:\u003c\/strong\u003e\u003c\/h3\u003e\n17J56, T6-2108, 65209300, 17J5601, 20516002.\u003c\/li\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eAllied\/Armstrong\/Ducane: \u003c\/strong\u003e\u003c\/h3\u003e\n66953. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eExtensive Model Compatibility List:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eNote: Use 'CTRL+F' to search for your specific model and revision number: \u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eLennox LD24 Series:\u003c\/strong\u003e\u003c\/h3\u003e\nLD24-75(A, S), LD24-100(A, S), LD24-125(A, S), LD24-150(A, S), LD24-200(A, S), LD24-250(A, S), LD24-300(A, S) (Various Revisions 01-04).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eLennox LF24 Series:\u003c\/strong\u003e\u003c\/h3\u003e\nLF24-30A, LF24-45A, LF24-50(A, S), LF24-60A, LF24-75(A, S), LF24-100(A, S), LF24-115(A, S), LF24-125(A, S), LF24-145(A, S), LF24-150(A, S), LF24-175(A, S), LF24-200(A, S), LF24-230(A, S), LF24-250(A, S), LF24-300(A, S), LF24-345(A, S), LF24-400(A, S) (Various Revisions).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eOther Compatible Models:\u003c\/strong\u003e\u003c\/h3\u003e\nSpecific models in the CGHA30, CGHA45, and CGHA60 series\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":52878279016811,"sku":"66255112542","price":35.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/17J56.jpg?v=1770053646"}],"url":"https:\/\/tophvacparts.com\/collections\/flame-sensor.oembed?page=2","provider":"HVAC Parts and Equipment Depot Open To Homeowners and Contractors","version":"1.0","type":"link"}
