Mounted on the heat-exchanger bulkhead, it senses supply-air temperature and cuts the burners if airflow is lost or the plenum overheats — protecting the heat exchanger from cracking. It automatically resets once temperatures return to a safe range.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eConfiguration: Normally closed, auto-reset\u003c\/li\u003e\n\u003cli\u003eFunction: Heat-exchanger overheat protection\u003c\/li\u003e\n\u003cli\u003eMounting: Bulkhead \/ vestibule panel\u003c\/li\u003e\n\u003cli\u003eApplication: 80% AFUE gas furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part #: 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 20162904 is factory-calibrated to the exact open\/close temperatures for this furnace and uses the correct mounting flange and probe length. Generic substitutes with different trip points can cause short-cycling on limit or, worse, fail to protect the heat exchanger. For a primary safety, OEM is strongly recommended.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (1\/5).\u003c\/strong\u003e Two spade terminals and two mounting screws.
