This normally-closed high-limit switch monitors heat-exchanger air temperature and cuts power to the gas valve if the furnace overheats — protecting the heat exchanger, blower, and surrounding components from thermal damage. If your furnace is short-cycling on high limit or failing to fire, a faulty limit switch is a common cause.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip temperature:\u003c\/strong\u003e 150°F (L150), auto-reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Normally closed (opens on temperature rise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary high-limit safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM part number:\u003c\/strong\u003e 20162903\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman \/ Amana AMH950704CXAF furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e This is the factory Goodman\/Amana component, calibrated to the exact trip point specified for the AMH950704CXAF.
