Mounted on the heat-exchanger or blower deck, the primary limit continuously senses supply-air temperature and interrupts the gas valve if the furnace overheats — most often from restricted airflow such as a clogged filter, closed registers, or a failing blower. It also coordinates blower operation to keep discharge temperatures within a safe range.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e 20162904\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Shuts off gas valve on overtemperature; manages blower response\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Automatic (self-resetting on cool-down)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman\/Amana AMES800804BXAA and compatible AMES80 furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe primary limit is calibrated to a specific trip temperature and mounting position unique to your furnace. OEM ensures the set point and bracket match exactly. A generic control with a different rating can nuisance-trip or, worse, fail to protect the heat exchanger.
