Mounted on the heat exchanger \/ plenum, this safety switch continuously monitors supply-air temperature and shuts off the burners if the furnace overheats — protecting the heat exchanger, blower, and your home from unsafe temperatures. A failed limit control is a common cause of short-cycling, no-heat lockouts, or a furnace that runs the blower but won't fire.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eType: Primary high-limit temperature control (auto-reset)\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat \/ high-temperature safety cutout\u003c\/li\u003e\n\u003cli\u003eFit: Goodman\/Amana AMEC800804BNAA and compatible furnaces\u003c\/li\u003e\n\u003cli\u003eMounting: Heat exchanger \/ plenum bracket\u003c\/li\u003e\n\u003cli\u003eOEM Part #: 20162904\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eOEM 20162904\u003c\/strong\u003e is calibrated to the exact trip and reset temperatures specified for this furnace, ensuring the burners cut out at the correct threshold. Generic limits with the wrong temperature rating can trip early (nuisance no-heat) or too late (a genuine safety risk).
