This high-limit rollout switch monitors heat-exchanger and burner-box temperatures, opening the control circuit to shut down the gas valve if a flame rollout or overheat condition is detected. Because it is a \u003cem\u003emanual reset\u003c\/em\u003e device, it will not automatically re-close after a trip — a deliberate safety feature that forces a technician to inspect the cause before the furnace restarts.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Manual reset high-limit \/ rollout switch\u003c\/li\u003e\n\u003cli\u003eFunction: Flame rollout \u0026amp; over-temperature protection\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman \/ Amana OEM\u003c\/li\u003e\n\u003cli\u003eDirect fit: ACES961205DNAA and related furnace platforms\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is the \u003cstrong\u003efactory OEM part (10123539)\u003c\/strong\u003e, calibrated to the exact trip temperature Goodman specifies for this furnace.
