Rated at \u003cstrong\u003e160°F\u003c\/strong\u003e, this auto-reset limit monitors supply-air temperature at the heat exchanger and shuts off the burners if the furnace overheats — the usual cause being a dirty filter, closed vents, or a failing blower. When a primary limit fails, you may see short-cycling on the heat call or no heat at all.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 160°F\u003c\/li\u003e\n\u003cli\u003eType: automatic-reset primary high-limit switch\u003c\/li\u003e\n\u003cli\u003eFunction: cuts burner operation on overheat\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMT140-5A and compatible Goodman \u0026amp; Amana furnaces\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1370187\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM B1370187 is factory-calibrated to the 160°F setpoint and uses the correct disc diameter and insertion depth for the GMT140-5A heat exchanger.
