Mounted at the heat exchanger \/ supply-air plenum, it continuously monitors discharge temperature and opens the burner circuit if the furnace overheats — the most common cause being restricted airflow from a dirty filter, blocked ducts, or a failing blower.\u003c\/p\u003e\u003cp\u003eUnlike the manual-reset rollout switch, the primary limit is typically an \u003cem\u003eauto-reset\u003c\/em\u003e control: it re-closes once temperature returns to a safe range. A furnace that short-cycles on heat, or one where the burners light but the blower\/limit behavior is erratic, often points to a limit control that has drifted out of calibration and needs replacement.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart type:\u003c\/strong\u003e Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Normally closed, opens on high temperature\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset:\u003c\/strong\u003e Automatic (snap-disc)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Bracket-mount over heat exchanger \/ plenum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Goodman\/Amana AMVC960603BNAA and compatible models\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eOEM vs. Generic:\u003c\/strong\u003e The OEM 20162904 ships with the correct trip\/reset set points and mounting bracket geometry for this furnace.
