This safety control opens the ignition circuit if the heat exchanger or plenum exceeds its rated cut-out temperature, shutting down the burners to prevent overheating. Unlike an auto-reset limit, this switch stays open until manually reset by pressing the button — a deliberate design that forces a technician to diagnose the root cause (blocked airflow, dirty filter, failed blower) before the furnace can run again.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Manual reset high-limit (SPST, normally closed)\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat \/ rollout safety cutoff\u003c\/li\u003e\n\u003cli\u003eFits: Goodman GDH80403ANBD and compatible 80% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 10123529\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 10123529\u003c\/strong\u003e is calibrated to the exact trip temperature Goodman engineered for this heat exchanger and mounts with the correct bracket geometry.
