This safety control opens the burner circuit if the heat exchanger or blower compartment exceeds its rated temperature, protecting your furnace from overheating caused by restricted airflow, a failed blower, or a dirty filter. Because it is a manual reset device, it requires a deliberate push of the reset button after a fault clears — alerting the homeowner or technician that a limiting condition occurred.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Manual reset high-limit \/ rollout safety switch\u003c\/li\u003e\n\u003cli\u003eFunction: Opens burner ignition circuit on over-temperature\u003c\/li\u003e\n\u003cli\u003eReset: Push-button manual reset\u003c\/li\u003e\n\u003cli\u003eFitment: Goodman GDH80403AXBC and compatible 80% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123529\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (genuine OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine OEM 10123529 is calibrated to the exact trip temperature specified for your furnace, ensuring the safety circuit behaves as the manufacturer intended.
