This safety component continuously monitors heat-exchanger and burner-compartment temperatures, tripping to cut gas and shut down the furnace if it detects an overheat condition caused by restricted airflow, a dirty filter, or a blower fault. Because it is a manual-reset design, it requires a deliberate button press to restore operation after a trip — a safeguard that forces a technician to investigate the root cause before the furnace runs again.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Manual reset high-limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123517\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (fits Amana equivalents)\u003c\/li\u003e\n\u003cli\u003ePrimary Fit: GCH91155DXAA gas furnace\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button\u003c\/li\u003e\n\u003cli\u003eApplication: Furnace overheat \/ flame rollout protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 10123517\u003c\/strong\u003e is calibrated to the exact trip temperature Goodman specifies for this furnace, ensuring the burner shuts down at the correct threshold.
