This high-limit control continuously monitors heat-exchanger temperature and cuts power to the gas valve if the furnace overheats — protecting the heat exchanger, blower, and your home from unsafe operating conditions. A failed limit switch is a common cause of short-cycling, no-heat calls, and safety lockouts.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e 20162904\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Type:\u003c\/strong\u003e Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Automatic overheat protection \/ burner cut-off\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Snap-disc auto-reset limit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (genuine OEM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits Model:\u003c\/strong\u003e GCH950453BXAD and related Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are calibrated to a specific trip temperature matched to the furnace's heat-exchanger design.
