If your furnace is tripping this limit, Diagnostic Check your air filter and evaporator coil for dirt buildup before installing the new 1370908S. A limit switch usually fails because it has been forced to \"cycle\" too many times due to restricted airflow; replacing the switch without fixing the airflow issue will lead to a repeat failure of the new part.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eCross-Reference\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eSuperseded \/ Legacy Numbers:\u003c\/strong\u003e\u003c\/h3\u003e\n1370908, B1370908, B13709-08, 0130F00038, 0130F00038S\u003c\/li\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eTexas Instruments \/ Klixon Equivalents:\u003c\/strong\u003e\u003c\/h3\u003e\n20500 Series L200-40\u003c\/li\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eWhite-Rodgers \/ Emerson Equivalents:\u003c\/strong\u003e\u003c\/h3\u003e\n3L01-200\u003c\/li\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eDrawing Numbers:\u003c\/strong\u003e\u003c\/h3\u003e\nB13709 Series Safety Controls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eModel Compatibility\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGMS8\u003c\/strong\u003e (Suffixes: 0403AX, 0603AX, 0804BX, 1005CX, 1205DX)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGDS8\u003c\/strong\u003e (Suffixes: 0403AX, 0603AX, 0804BX, 1005CX)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGMP \u003c\/strong\u003e(Suffixes: 050-3, 075-3, 100-3, 100-4, 125-5)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGMPN \u003c\/strong\u003e(Suffixes: 040-3, 060-3, 080-4, 100-4)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGHS8 \u003c\/strong\u003e(Suffixes: 0403AX, 0603AX, 0804BX)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGMNT \u003c\/strong\u003e(Suffixes: 040-3, 060-3, 080-4, 100-4, 120-5)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":52759404151147,"sku":"1370908S","price":55.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0922\/9683\/9531\/files\/1370908S.jpg?v=1768512357","url":"https:\/\/tophvacparts.com\/products\/goodman-1370908s-furnace-limit-switch-200-f-l200-40f-oem-hvac-safety-control-switch-24-volt","provider":"HVAC Parts and Equipment Depot","version":"1.0","type":"link"}
