This switch monitors heat-exchanger and plenum temperature and trips to shut off the burners if the furnace overheats — a common result of restricted airflow, a dirty filter, or blower failure. Because it is a \u003cstrong\u003emanual reset\u003c\/strong\u003e design, it will not auto-cycle after a fault: it stays open until the button is pressed, forcing you to investigate the root cause. That is exactly the behavior you want from a life-safety limit.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 10123519\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Manual reset high-limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Overheat \/ rollout safety shutoff\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman GKS91155DXAC furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Manual (push-button)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are rated to a specific open temperature.
