This normally-closed high-limit safety opens the burner circuit if furnace temperatures climb past its trip point — protecting the heat exchanger and cabinet from overheating caused by restricted airflow, a dirty filter, or a failed blower. A limit that has tripped permanently or drifted out of calibration will prevent the furnace from firing or cause repeated shutdowns.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip temperature:\u003c\/strong\u003e 160°F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProbe \/ mount length:\u003c\/strong\u003e 3 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContacts:\u003c\/strong\u003e Normally closed, auto-reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e High-temperature safety limit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GDT070-3 and compatible furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman 1370909S\u003c\/strong\u003e is calibrated to the exact 160°F trip point and 3-inch insertion depth Goodman engineered for this furnace.
