Mounted on the heat-exchanger\/blower bulkhead, this auto-reset thermal control watches supply-air temperature. If airflow is lost or the plenum overheats past its setpoint, it opens the control circuit to cut the burners and protect the heat exchanger, then closes again automatically once temperatures return to normal.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 20162903 (OEM Goodman)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary high-limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet Point:\u003c\/strong\u003e 150°F trip temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContacts:\u003c\/strong\u003e Normally closed, automatic reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Over-temperature \/ airflow-loss safety\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMS80805CXAA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine OEM 20162903 carries Goodman's exact 150°F calibration, disc size, and bracket footprint, so it trips at the correct temperature and mounts without modification. Generic limits with a different setpoint can cause short cycling or fail to protect the furnace.
