It is a direct-fit replacement for the safety limit used on the \u003cstrong\u003eGoodman GDH80403ANBB\u003c\/strong\u003e and other compatible 80% AFUE gas furnaces in the Goodman and Amana families. Because it requires a \u003cstrong\u003emanual reset\u003c\/strong\u003e, a tripped switch signals that a fault occurred — restricted airflow, a dirty filter, or a blocked flue — and should be diagnosed, not just reset repeatedly. A failed or nuisance-tripping switch causes no-heat lockouts.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 10123529\u003c\/li\u003e\n\u003cli\u003eType: Manual reset high-limit \/ rollout switch\u003c\/li\u003e\n\u003cli\u003eFunction: Normally closed; opens on over-temperature\u003c\/li\u003e\n\u003cli\u003eReset: Manual push-button\u003c\/li\u003e\n\u003cli\u003eFits Model: GDH80403ANBB (and compatible Goodman\/Amana furnaces)\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas Furnace, 80% AFUE\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 \u003cstrong\u003egenuine Goodman OEM limit switch\u003c\/strong\u003e is factory-set to the exact trip temperature your furnace was certified for.
