Installed on the heat exchanger or supply plenum, this control is the furnace's main overheat protection — it opens the gas valve circuit if supply air temperature climbs too high, usually due to insufficient airflow. A furnace that short-cycles on heat or won't stay lit often has a tripping or failed primary limit.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 300°F (opens on rise, auto-reset)\u003c\/li\u003e\n\u003cli\u003eType: primary high-limit switch\u003c\/li\u003e\n\u003cli\u003eFunction: heat exchanger \/ supply air overheat cutout\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GDS80904BXA furnace\u003c\/li\u003e\n\u003cli\u003eOEM part number: B1370195\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman B1370195\u003c\/strong\u003e is factory-calibrated to the exact 300°F set point and insertion depth your furnace requires.
