Mounted on the burner bracket, it is a normally-closed safety control that opens and cuts power to the gas valve if it senses abnormal heat from flame rollout — a serious condition usually caused by a blocked heat exchanger or restricted venting. Because it is manual-reset, it stays open until the button is physically pressed, forcing the homeowner or technician to investigate before the furnace can restart.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 10123529\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual-reset flame-rollout limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Normally closed; opens on overtemp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual push-button\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman VMS80804BNAA gas furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 10123529 is calibrated to the exact trip temperature Goodman's engineering specifies for this furnace.
