This thermally-activated safety switch opens the control circuit if it senses excessive temperature — typically from restricted airflow, a dirty filter, or blower failure — shutting down the burners to prevent heat-exchanger damage. As an auto-reset device, it closes again once the sensed temperature returns to a safe range.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 20269903 (OEM Goodman\/Amana)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Auxiliary high-limit switch, auto-reset\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Overheat \/ airflow-failure protection\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Automatic (SPST, opens on temperature rise)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnections:\u003c\/strong\u003e Quick-connect spade terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e AMV80704BXBA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold:\u003c\/strong\u003e Each\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 20269903\u003c\/strong\u003e is calibrated to the exact open\/close trip temperature Goodman specifies for this furnace, so it protects the heat exchanger without nuisance tripping.
