Mounted on the heat exchanger, it continuously monitors supply-air temperature and opens the control circuit to shut off the burners if the furnace overheats — typically caused by restricted airflow, a dirty filter, or blower failure. Unlike a manual-reset limit, the primary limit is an auto-reset control that restores heating once temperatures return to a safe range.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eFunction: Normally closed, opens on overheat, auto-reset\u003c\/li\u003e\n\u003cli\u003eMounting: Heat exchanger \/ supply air\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana VMES961005CNAA furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eGenuine OEM 20162904\u003c\/strong\u003e is factory-calibrated to the trip temperature and sensor length specified for this furnace.
