Mounted on the heat exchanger or blower deck, this control monitors supply-air temperature and shuts off the gas valve if the furnace overheats — typically due to a dirty filter, closed dampers, or a failing blower. It protects the heat exchanger from thermal stress and cracking.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary auto-reset high-limit (temperature) switch\u003c\/li\u003e\n\u003cli\u003eCutout Temperature: 150°F\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003cli\u003eFunction: Normally closed, opens on over-temperature\u003c\/li\u003e\n\u003cli\u003eFits: Goodman \u0026amp; Amana AMS81205DXAC and compatible furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe 150°F set point and mounting-flange dimensions of the OEM 20162903 are specific to this furnace's cabinet and airflow design.
