Mounted on the heat-exchanger\/blower bulkhead, the primary limit monitors supply-air temperature and shuts off the burners if the furnace overheats — typically from restricted airflow, a dirty filter, a failing blower, or closed registers. It is an automatic-reset control that recloses once temperatures return to normal.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart type:\u003c\/strong\u003e Primary high-limit switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrip temperature:\u003c\/strong\u003e 150°F (factory-set open point)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM part number:\u003c\/strong\u003e 20162903\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset type:\u003c\/strong\u003e Automatic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman\/Amana AMVC80604BXAA furnace\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e New, genuine OEM\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The 150°F set point and mounting-bracket geometry are matched to this furnace's cabinet and airflow design. A generic limit with a different temperature or bracket can cause repeated shutdowns or bypass protection entirely. The genuine 20162903 delivers the exact trip point and fit the furnace was engineered around, keeping the high-limit safety chain intact.
