Mounted on the heat-exchanger bulkhead, it monitors supply-air temperature and shuts off the gas valve if the furnace overheats due to a dirty filter, blocked ductwork, or a failed blower. Replacing a nuisance-tripping or open limit with the correct OEM part restores reliable heat and keeps the safety chain intact.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary auto-reset high-limit control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Opens gas circuit on over-temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Factory bracket \/ bulkhead location\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMEC800803BXAA and related Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part #:\u003c\/strong\u003e 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are calibrated to a specific cut-out temperature matched to the furnace's heat exchanger.
