This normally-closed safety control senses excessive temperature at the burner compartment — a symptom of flame rollout caused by a blocked flue, cracked heat exchanger, or restricted combustion air. When tripped, it cuts power to the gas valve and locks out until an operator physically presses the reset button, preventing continued unsafe firing.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Manual reset flame rollout limit switch\u003c\/li\u003e\n\u003cli\u003eAction: Normally closed, opens on high temperature\u003c\/li\u003e\n\u003cli\u003eReset: Manual (push-button)\u003c\/li\u003e\n\u003cli\u003eOEM part number: 10123529\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana (interchangeable)\u003c\/li\u003e\n\u003cli\u003ePrimary fit: AMH80403ANBA and related AMH8 furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a life-safety device, so exact trip temperature and disc calibration matter.
