This thermal cutout monitors heat-exchanger and plenum temperatures, opening the burner circuit if the furnace overheats to protect against fire and component damage. Because it is a manual-reset design, it requires a technician to press the reset button after a trip — a deliberate safety feature that flags an underlying airflow or venting problem rather than silently cycling.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Manual reset high-limit safety switch\u003c\/li\u003e\n\u003cli\u003eReset: Manual (push-button)\u003c\/li\u003e\n\u003cli\u003eCompatibility: Goodman GCH90453BXAA and related 90% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003eFunction: Opens burner\/gas circuit on over-temperature\u003c\/li\u003e\n\u003cli\u003eBrand: Genuine Goodman OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis is a genuine Goodman OEM part with the exact trip temperature and mounting footprint specified for your furnace.
