Mounted on the heat exchanger\/plenum, this high-limit switch monitors supply-air temperature and shuts off the burners if the furnace overheats — typically from restricted airflow such as a dirty filter, closed registers, or a failing blower. It is the furnace's primary overheat protection.\u003c\/p\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 (auto-reset)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFits:\u003c\/strong\u003e Goodman\/Amana AMS80603AXAD 80% AFUE furnaces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAction:\u003c\/strong\u003e Normally closed, opens on overtemp, auto-resets on cooldown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Factory bracket with insertion probe\/disc\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM 20162904 arrives with the exact trip temperature, probe length, and mounting bracket for the AMS80603AXAD.
