This normally-closed switch monitors furnace temperature and opens to cut the burners if heat rises beyond a safe threshold — a core safety feature that protects the heat exchanger and blower assembly. When this switch fails open, the furnace may lock out or refuse to fire; when it fails closed, overheating protection is lost.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 10728343\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e High-temperature limit \/ safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Normally closed, opens on high temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GMPE100-4A furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e Spade connectors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman\u003c\/strong\u003e switch carries the correct trip temperature and mounting footprint for the GMPE100-4A.
