Its 3-inch bimetal probe inserts into the heat-exchanger air stream and opens at 160°F if supply-air temperature climbs too high — typically from a dirty filter, blocked ductwork, or a failing blower. This shuts off the burners to prevent heat-exchanger damage, then auto-resets as the cabinet cools.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 1370909S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e High-limit thermal switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Temperature:\u003c\/strong\u003e 160°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProbe Length:\u003c\/strong\u003e 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAction:\u003c\/strong\u003e Automatic reset, normally closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e GDS81155CXA (and compatible Goodman\/Amana furnaces)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman Genuine OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eGenuine Goodman OEM\u003c\/strong\u003e switch guarantees the exact 160°F trip point and correct 3-inch insertion depth so the sensor reads true plenum temperature.
