This normally-closed switch opens and cuts power to the gas valve if it senses an overheat or flame-rollout condition, protecting the heat exchanger and cabinet. Because it is a manual-reset design, it stays tripped until a technician presses the reset button — a deliberate safeguard that flags a fault needing inspection rather than silently cycling.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Manual reset high-limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eAction: Normally closed, opens on overtemperature\u003c\/li\u003e\n\u003cli\u003eReset: Manual (push-button)\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123529\u003c\/li\u003e\n\u003cli\u003eFits: Goodman\/Amana AMS81405DNBB gas furnace\u003c\/li\u003e\n\u003cli\u003eTerminals: 1\/4\" quick-connect spades\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe trip temperature and mounting footprint of a limit switch are safety-critical. OEM part 10123529 is calibrated to the exact set point your furnace's certification requires. Generic switches with the wrong trip point can either nuisance-trip or, worse, fail to protect the heat exchanger. For a safety device, always install OEM.\u003c\/p\u003e\u003ch3\u003eInstall Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5).\u003c\/strong\u003e Two spade terminals and two mounting screws.
