Mounted on the heat-exchanger\/blower deck, it monitors supply-air temperature and opens the gas\/ignition circuit if the furnace overheats — protecting the heat exchanger from cracking and preventing an unsafe operating condition. A failed limit is a leading cause of a furnace that short-cycles, blows cold air, or won't fire at all.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 20162904 (OEM Goodman\/Amana)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auto-reset primary high-limit control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Opens burner circuit on over-temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Factory bracket on the blower\/heat-exchanger panel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMH950453BXAC 95% AFUE furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e A limit switch is a life-safety device — its trip and reset temperatures must match the furnace's design. Generic limits with the wrong set point either nuisance-trip on normal operation or, worse, fail to trip when they should. This OEM control is calibrated to Goodman's exact cut-out temperature and uses the correct sensing-element length and bracket for an exact fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstall difficulty:\u003c\/strong\u003e Moderate (2\/5).
