Mounted on the heat exchanger or burner box, this thermally activated switch continuously monitors supply-air temperature and shuts off the burners if the furnace overheats — protecting the heat exchanger and preventing unsafe operation. A failed or nuisance-tripping limit is a common cause of furnaces that short-cycle or won't fire, so an exact-fit replacement restores safe, dependable heating.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Primary high-limit safety control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auto-reset thermal limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Overheat protection \/ burner cutoff\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part #:\u003c\/strong\u003e 20162904\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits model:\u003c\/strong\u003e AMS80603AXAA (and compatible Goodman\/Amana furnaces)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003egenuine Goodman OEM limit control\u003c\/strong\u003e is calibrated to your furnace's exact trip temperature and cut-in point.
