Mounted on the heat-exchanger partition, the primary limit is the furnace's main overheat protector: it opens the heating circuit and shuts down the burners if supply-air temperature climbs past the safe threshold, guarding the heat exchanger against cracking. A furnace that heats briefly then shuts off, or short-cycles on the limit, often needs this part.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip temperature:\u003c\/strong\u003e 160°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset type:\u003c\/strong\u003e Automatic reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Primary high-limit safety control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Goodman\/Amana AMH80703ANAC and compatible furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e 1\/4 in. quick-connect spade\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e Genuine OEM B1370187 is set to the exact 160°F cutout and insertion-depth your furnace requires.
