Mounted on the heat-exchanger\/plenum, the primary limit is the furnace's main overheat safety: it opens and cuts the gas valve when supply-air temperature exceeds the safe threshold, then cycles the blower to dissipate residual heat. A tripped or open primary limit is a leading cause of intermittent no-heat and short-cycling complaints.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: B1370189\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 200°F\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit (auto-reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Heat-exchanger \/ supply-air overheat protection\u003c\/li\u003e\n\u003cli\u003eFits Model: ADV80905CXBB and related Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eTerminals: 1\/4\" spade connectors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM B1370189\u003c\/strong\u003e is calibrated to Goodman's exact 200°F set point and probe\/bracket dimensions, matching the furnace's engineered limit.
