Mounted on the heat-exchanger\/blower bulkhead, it continuously senses supply-air temperature and shuts down the burners if the furnace overheats — typically from restricted airflow, a dirty filter, or a failing blower. As the primary limit, it is the furnace's front-line thermal protection and a required safety component for legal, reliable operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 20162904\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (OEM)\u003c\/li\u003e\n\u003cli\u003eEquipment: Gas Furnace\u003c\/li\u003e\n\u003cli\u003eFits Model: GKS90453BXAA\u003c\/li\u003e\n\u003cli\u003eFunction: Over-temperature burner shutdown\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine 20162904 is factory-calibrated to the precise open\/close temperatures, insertion depth, and mounting footprint this furnace requires. Generic limit controls with approximate ratings risk nuisance lockouts or delayed tripping — unacceptable on a primary safety circuit. For this component, OEM is the correct and recommended choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eEasy (2\/5).\u003c\/strong\u003e Replacement usually takes 15–25 minutes: cut power, remove the two mounting screws, transfer the wiring, and seat the new control at the same insertion depth. If the limit continues to trip, have a technician investigate airflow, filter condition, and blower performance rather than bypassing the control.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63058085314931,"sku":"GOODMAN-10524","price":35.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-temperature-control-for-gks90453bxaa-20162904","provider":"National HVAC Parts","version":"1.0","type":"link"}
