Mounted on the heat exchanger\/blower deck, this high-limit control continuously monitors supply-air temperature and opens the circuit to shut off the burners if the furnace overheats—protecting the heat exchanger from cracking and preventing a fire hazard when airflow is restricted by a dirty filter or failed blower.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162904\u003c\/li\u003e\n\u003cli\u003eType: Primary (high) limit temperature control\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat safety cutout\u003c\/li\u003e\n\u003cli\u003eFits: AMEC960804CNAB and compatible Goodman\/Amana furnaces\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (temperature-sensing)\u003c\/li\u003e\n\u003cli\u003eFactory-calibrated trip point\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe genuine 20162904 is calibrated to the precise trip temperature this furnace requires.
