This manual-reset high-limit (rollout) switch monitors combustion temperature and trips to shut off the burner if it detects an unsafe overheat or flame-rollout condition, protecting the heat exchanger and your home from potential damage. Because it is a manual-reset design, it will not automatically re-energize after a fault — requiring a technician to inspect the cause and press the reset button, an intentional safety feature.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10123519\u003c\/li\u003e\n\u003cli\u003eType: Manual reset limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: High-temperature burner cutoff\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GCH90703BXAA and select Goodman\/Amana gas furnaces\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas Furnace\u003c\/li\u003e\n\u003cli\u003eBrand: Genuine Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine OEM 10123519 switches are calibrated to the exact trip temperature specified for your furnace.
