This safety cutout monitors heat-exchanger temperature and shuts off the burners if the furnace overheats — protecting the heat exchanger, blower, and your home from dangerous conditions caused by restricted airflow or a dirty filter. A failed limit switch causes short-cycling, no-heat calls, or a furnace that won't fire at all.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eTrip temperature: 150°F (opens on rise)\u003c\/li\u003e\n\u003cli\u003eType: Automatic-reset primary high limit\u003c\/li\u003e\n\u003cli\u003eFits: AMEH800805DXAA and compatible AMEH80 furnaces\u003c\/li\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003cli\u003eFunction: Overheat safety shutoff for burner circuit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 20162903 is calibrated to the exact 150°F trip point and mounting footprint your furnace requires.
