Mounted on the heat exchanger vestibule, this normally-closed switch opens at approximately 150°F to shut down the burners if the furnace overheats — protecting the heat exchanger, blower, and your home from unsafe temperatures. If your furnace is short-cycling on heat or the burners ignite then drop out, a failed limit switch is a common cause.\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\u003eFunction:\u003c\/strong\u003e Primary high-limit safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Point:\u003c\/strong\u003e 150°F (open on rise, auto-reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Type:\u003c\/strong\u003e Normally closed (SPST)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e AMH80805CXBA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Genuine Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a \u003cstrong\u003efactory OEM Goodman\u003c\/strong\u003e part built to the exact trip temperature and mounting footprint your furnace's control logic expects.
