Installed on the heat-exchanger\/supply-air side, this auto-reset limit monitors plenum temperature and shuts off the burners if the furnace overheats due to insufficient airflow, protecting the heat exchanger from cracking. It is a factory-spec replacement that fits Goodman and Amana furnaces built on the same chassis.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Limit Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e B1370198\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip Temperature:\u003c\/strong\u003e 150°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary high limit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMH81405DNAC and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine OEM B1370198 delivers the exact 150°F trip point and mounting geometry the furnace's safety design depends on.
