This normally-closed switch monitors heat-exchanger and blower-compartment temperature and opens the circuit to shut off the burners if the furnace overheats — protecting against restricted airflow, dirty filters, or blower failure. Unlike an auto-reset control, it must be manually reset after a trip, prompting the homeowner or technician to investigate the root cause.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Type: Manual reset high-limit switch\u003c\/li\u003e\n\u003cli\u003eColor: Gray\u003c\/li\u003e\n\u003cli\u003eAction: Normally closed, opens on overtemperature\u003c\/li\u003e\n\u003cli\u003eReset: Manual (press-to-reset button)\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123537\u003c\/li\u003e\n\u003cli\u003eFit: Direct OEM replacement for AMV90905DXAB\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 10123537 is calibrated to the exact trip temperature specified for the AMV90905DXAB, ensuring the furnace shuts down at the safe threshold. A generic limit switch with a different setpoint or mounting footprint can nuisance-trip, fail to protect the heat exchanger, or fit poorly.
