This normally-closed switch opens and shuts off the gas valve if the furnace overheats or experiences flame rollout, then requires a manual press of the reset button to restore operation. A tripped or failed limit switch is a frequent cause of a furnace that fires briefly then shuts down (short-cycling) or that stops heating entirely on a safety lockout.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 10123529\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual-Reset High-Limit \/ Rollout Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Normally Closed (opens on temperature rise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual push-button\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman \/ Amana (interchangeable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMH80403ANAA and compatible Goodman\/Amana 80% furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Overheat \u0026amp; flame-rollout safety shutoff\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine \u003cstrong\u003eOEM 10123529\u003c\/strong\u003e is calibrated to the exact trip temperature specified for your furnace model — critical for a safety component.
