Mounted on the heat exchanger or blower housing, it monitors supply-air temperature and shuts off the gas valve if the furnace overheats — a critical safety device that prevents heat-exchanger damage and fire hazards. A failed limit switch causes short cycling, no-heat conditions, or a furnace that won't fire at all.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 20162903\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary high-limit switch (auto-reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Temperature:\u003c\/strong\u003e 150°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e GKS90703BXAA and compatible Goodman furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e High-temperature safety cutoff for the gas valve circuit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine Goodman limit switch is calibrated to the exact 150°F trip point this furnace requires.
