This temperature-sensing safety control opens the burner circuit whenever the furnace exceeds its safe operating range, guarding the heat exchanger against damage from restricted airflow or blower failure. As a manual reset switch, it will not automatically re-energize after a trip — a technician must press the reset button, which encourages diagnosis of the underlying fault before the unit resumes heating.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Manual reset high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: Interrupts burner circuit on overtemperature\u003c\/li\u003e\n\u003cli\u003eMounting: Direct OEM replacement fit\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman GCH90704CXAB and related furnace platforms\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123518\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eGenuine OEM 10123518 switches are factory-calibrated to your furnace's exact trip temperature, delivering reliable, code-compliant protection.
