Mounted on the heat-exchanger bulkhead, it continuously monitors supply-air temperature and shuts off the burners if the furnace overheats — typically from a dirty filter, blocked ductwork, or a failed blower. This automatic-reset control is essential for protecting the heat exchanger from cracking.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Type: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (snap-disc)\u003c\/li\u003e\n\u003cli\u003eFunction: Opens burner circuit on over-temperature\u003c\/li\u003e\n\u003cli\u003eMounting: Heat-exchanger \/ plenum bracket\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GMS950904CXA and compatible furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM Goodman 20162904\u003c\/strong\u003e is calibrated to your furnace's exact cut-out and cut-in temperatures and uses the correct bracket geometry for proper airflow sensing.
