Mounted on the heat-exchanger\/burner bulkhead, this 210°F auto-reset switch protects the furnace from overheating when airflow across the heat exchanger drops. When it opens, the gas valve de-energizes and the blower continues to purge heat—preventing heat-exchanger damage and cracking.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip temperature:\u003c\/strong\u003e 210°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 \/ airflow safety\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminals:\u003c\/strong\u003e 1\/4\" male quick-connect\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman\/Amana AMS80453ANA and compatible furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part #:\u003c\/strong\u003e B1370190\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman B1370190\u003c\/strong\u003e delivers the precise 210°F setpoint and factory-matched mounting for guaranteed fit and safety-listing compliance.
