The Goodman 20162904 is a genuine OEM primary limit temperature control designed for AMH80604BXBA gas furnaces and compatible Goodman/Amana models. Mounted on the heat exchanger or burner box, the primary limit continuously monitors supply-air temperature and cuts the burners if the furnace overheats — typically due to restricted airflow, a dirty filter, or blower failure. It is one of the most important safety controls in the appliance.
