This thermally activated safety control monitors heat-exchanger temperature and shuts off the burners if the furnace overheats — typically from restricted airflow, a dirty filter, or blower failure. When the limit trips repeatedly or fails open, the furnace won't fire; a failed or out-of-spec limit is a common no-heat cause.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 20162901\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary high-limit \/ overheat safety switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Cuts burner operation on over-temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman VCSS960402BNAA and compatible furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Automatic (temperature-sensing bimetal)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM Goodman limit switch is calibrated to the exact trip and reset temperatures Goodman specifies for this heat exchanger, and its bracket matches the factory mounting location. Generic limits with different setpoints can nuisance-trip or, worse, fail to protect the furnace. For a life-safety component, the factory-calibrated OEM switch is the right call.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate\u003c\/strong\u003e — Disconnect power, remove the two mounting screws and wiring connectors, and install the new switch in the same orientation. About 20–30 minutes with basic tools. If the old limit was tripping, diagnose the underlying airflow issue before returning the unit to service.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058202034547,"sku":"GOODMAN-20162901","price":39.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-switch-for-vcss960402bnaa-furnace-20162901","provider":"National HVAC Parts","version":"1.0","type":"link"}
