This normally-closed thermal switch opens at approximately 120°F to protect the blower compartment and heat exchanger from overheating, shutting the furnace down before unsafe temperatures are reached. A failed auxiliary limit is a common cause of a furnace that short-cycles, throws a limit fault code, or 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 B1370155\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auxiliary limit switch (thermal cutout)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Temperature:\u003c\/strong\u003e 120°F (auto-reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e AMH80453AXAA (80% AFUE gas furnace)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContacts:\u003c\/strong\u003e Normally closed, opens on rise\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a factory OEM part built to Goodman's exact trip-point tolerance.
