Mounted on the heat-exchanger\/plenum, it opens the gas valve circuit if supply-air temperature climbs too high — typically from a dirty filter, blocked ductwork, or a failing blower. A defective limit causes intermittent shutdowns or, worse, fails to protect the exchanger.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary auto-reset high-limit switch\u003c\/li\u003e\n\u003cli\u003eTrip Setpoint: 150°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003eElectrical: Normally closed, snap-disc action\u003c\/li\u003e\n\u003cli\u003eMounting: Flange\/bracket, OEM plenum location\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMS80805CXAC and related furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 20162903 is matched to the exact 150°F setpoint and disc geometry engineered for this furnace.
