Mounted on the heat exchanger \/ blower deck, this factory-calibrated switch continuously monitors supply-air temperature and opens the ignition circuit if the furnace overheats — for example when a dirty filter, blocked duct, or failed blower restricts airflow. It is a critical life-safety component that protects the heat exchanger from thermal stress and cracking.\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 (auto-reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Opens the burner\/ignition circuit on over-temperature\u003c\/li\u003e\n\u003cli\u003eCalibration: Factory-set trip point specific to the AMVC960803BNAA platform\u003c\/li\u003e\n\u003cli\u003eFit: OEM-exact for AMVC960803BNAA and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (Amana family)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eBecause this is a safety device, the trip temperature and mounting geometry must match the furnace exactly. The OEM 20162904 arrives calibrated to Goodman's engineered set point. Generic or cross-referenced limits with the wrong temperature rating can trip prematurely (nuisance lockouts) or — worse — fail to trip in time, defeating overheat protection. Always use the genuine part for high-limit replacement.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate.\u003c\/strong\u003e Disconnect electrical power and shut off gas before starting. Remove the blower\/heat-exchanger access panel, note the wire terminal orientation, unscrew the old limit, and install the new 20162904 in the same position with the same wiring. Test furnace operation and cycle for proper limit function afterward. If you are not comfortable working near the heat exchanger, use a licensed HVAC technician.\u003c\/p\u003e\u003cp\u003eProtect your AMVC960803BNAA furnace with the genuine Goodman 20162904 primary limit control.\u003c\/p\u003e","brand":"Goodman","offers":[{"title":"Default Title","offer_id":63057996087667,"sku":"GOODMAN-9044","price":59.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-goodman-primary-limit-temperature-control-for-amvc960803bnaa-20162904","provider":"National HVAC Parts","version":"1.0","type":"link"}
