This thermal safety device opens the heating circuit if it detects an overheat condition — typically from restricted airflow or a failed blower — protecting the heat exchanger and home from damage. Because it is a manual-reset type, it must be physically reset (and the root cause cleared) after a trip, making it a true last-line safety control.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eComponent: Manual reset high-limit \/ rollout switch\u003c\/li\u003e\n\u003cli\u003eFunction: Thermal overheat safety cutout\u003c\/li\u003e\n\u003cli\u003eReset type: Manual (push-button)\u003c\/li\u003e\n\u003cli\u003eApplication: Gas furnace heat section\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \/ Amana ACES800403ANAA\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123529\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 10123529 is factory-calibrated to the furnace's exact trip temperature and matches the original mounting footprint and terminal type.
