This normally-closed thermal switch opens the ignition circuit if it senses excessive temperature — such as from a blocked heat exchanger, flame rollout, or restricted airflow — and must be manually reset once the fault is cleared. It's a critical safety device that protects the furnace and home from overheating and combustion hazards.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10123519\u003c\/li\u003e\n\u003cli\u003eType: Manual reset high-limit \/ rollout switch (normally closed)\u003c\/li\u003e\n\u003cli\u003eReset: Manual (push-button)\u003c\/li\u003e\n\u003cli\u003eCompatible Model: GMH951155DXAG (95% AFUE)\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temperature \/ flame rollout safety shutoff\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eLimit switches are calibrated to a specific trip temperature.
