Mounted on the heat-exchanger bulkhead, this auto-reset control continuously monitors supply-air temperature and cuts power to the burners if the furnace overheats — typically from restricted airflow, a dirty filter, or blower failure. It is the primary defense against a cracked heat exchanger and overheating damage.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 20162904\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit temperature control\u003c\/li\u003e\n\u003cli\u003eReset: Automatic (recloses when temperature falls)\u003c\/li\u003e\n\u003cli\u003eContacts: Normally closed, opens on high temperature\u003c\/li\u003e\n\u003cli\u003eFunction: Supply-air over-temperature burner cutoff\u003c\/li\u003e\n\u003cli\u003eMounting: Factory bulkhead location with L-bracket\u003c\/li\u003e\n\u003cli\u003eFits: AMH80604BNBD and related furnaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThis \u003cstrong\u003eOEM Goodman limit control\u003c\/strong\u003e is factory-calibrated to the precise trip temperature and insertion depth for your model.
