Mounted on the heat exchanger \/ plenum, this primary high-limit senses supply-air temperature and interrupts the burner circuit if the furnace overheats — typically from restricted airflow, a dirty filter, or a failing blower. As an auto-reset control, it closes again once temperatures return to normal, cycling the furnace off and on to keep the heat exchanger within safe limits.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart type: Primary limit temperature control (auto-reset high-limit)\u003c\/li\u003e\n\u003cli\u003eOEM part number: 20162904\u003c\/li\u003e\n\u003cli\u003eAction: Normally closed, opens on overtemperature, auto-reset\u003c\/li\u003e\n\u003cli\u003eFunction: Supply-air \/ heat-exchanger overheat protection\u003c\/li\u003e\n\u003cli\u003eFits: AMEC800805DXAA and related Goodman\/Amana furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe primary limit is factory-matched to the furnace's cabinet geometry and trip temperature.
