Mounted on the heat exchanger or blower housing, the primary limit switch monitors supply-air temperature and shuts off the burners if the furnace overheats — a critical safety function that prevents heat exchanger damage and fire risk. A failed limit switch is a common cause of short-cycling, no-heat calls, or a furnace that runs the blower but won't fire.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 20162903\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Primary (High) Limit Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Temperature:\u003c\/strong\u003e 150°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Auto-reset high-limit safety\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e GKS90703BXAC (and compatible Goodman furnaces)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch is calibrated to the exact 150°F trip point specified for this furnace.
