This high-limit switch continuously monitors heat-exchanger temperature and cuts power to the gas valve if the furnace overheats — protecting your equipment and your home. A failed limit switch is a common cause of a furnace that short-cycles, trips on high temperature, or fails to fire.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary (high) limit switch, automatic reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip point:\u003c\/strong\u003e 150°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Over-temperature safety cutout for the heat exchanger\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Direct OEM replacement for GKS90905DXAF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (also fits many Amana furnaces)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eOur \u003cstrong\u003eOEM version\u003c\/strong\u003e is the factory-specified part with the exact trip temperature, mounting flange, and terminal layout your furnace's control board expects — the safest, guaranteed-fit choice.
