Mounted on the heat-exchanger or blower deck, the primary limit monitors supply-air temperature and shuts off the burners if the furnace overheats — typically from restricted airflow, a dirty filter, or a failing blower. Its 150°F set point keeps the heat exchanger within safe operating temperature and protects the appliance and ductwork.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Primary high-limit switch\u003c\/li\u003e\n\u003cli\u003eOEM part number: 20162903\u003c\/li\u003e\n\u003cli\u003eTrip set point: 150°F\u003c\/li\u003e\n\u003cli\u003eReset type: Automatic (closes on temperature drop)\u003c\/li\u003e\n\u003cli\u003eFits model: AMH80805CNBA (Amana \/ Goodman gas furnace)\u003c\/li\u003e\n\u003cli\u003eFunction: Overtemperature burner shutdown\u003c\/li\u003e\n\u003cli\u003eSold individually\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003egenuine OEM 20162903\u003c\/strong\u003e ships with the correct 150°F calibration, insertion depth, and mounting flange for this furnace.
