Mounted on the heat exchanger\/blower deck, this auto-reset limit switch monitors supply-air temperature and shuts off the gas valve if the furnace overheats — typically from restricted airflow, a dirty filter, or blower failure. It automatically restores the circuit once temperatures return to a safe range.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 20162904 (OEM Goodman)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Automatic (temperature-actuated)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Overheat safety cutout for the gas valve circuit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GKS90904CXAC and related 90-series furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe trip temperature and probe length of a primary limit are matched precisely to your furnace's heat exchanger.
