Mounted on the heat exchanger deck, it opens the burner circuit if supply-air temperature climbs too high, preventing heat-exchanger damage from restricted airflow. A failed primary limit is a common cause of furnace short-cycling or a no-heat condition.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 150°F (high-limit, opens on rise)\u003c\/li\u003e\n\u003cli\u003eType: primary\/high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eAuto-reset on temperature drop\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMH80903BNAB and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1370198\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B1370198\u003c\/strong\u003e is calibrated to the exact 150°F trip point and probe length your furnace requires.
