Mounted on the heat-exchanger bulkhead, the primary limit continuously watches supply-air temperature and opens the circuit to shut off the burners if the furnace overheats — the classic symptom of a dirty filter, closed registers, a failing blower, or restricted ductwork. Once the cabinet cools below the setpoint, this auto-reset switch closes again and allows normal operation to resume.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Primary high-limit switch\u003c\/li\u003e\n\u003cli\u003eTrip point: 150°F (factory calibrated)\u003c\/li\u003e\n\u003cli\u003eReset: Automatic\u003c\/li\u003e\n\u003cli\u003eAction: Normally closed, opens on overtemperature\u003c\/li\u003e\n\u003cli\u003eOEM part number: 20162903\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMSS960804CNAA and compatible 96% AFUE furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe trip temperature and disc response curve are matched to this furnace's heat-exchanger geometry.
