Mounted on the heat-exchanger plenum, this high-limit control monitors supply-air temperature and shuts off the burners if the furnace overheats due to a dirty filter, blocked ducts, or blower failure. It protects the heat exchanger from cracking and prevents unsafe operating temperatures.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTrip point: 150°F cutout (primary high limit)\u003c\/li\u003e\n\u003cli\u003eType: Auto-reset temperature limit switch\u003c\/li\u003e\n\u003cli\u003eFunction: Disables burners on over-temperature\u003c\/li\u003e\n\u003cli\u003eTerminals: 1\/4 in. quick-connect spade\u003c\/li\u003e\n\u003cli\u003eFit: Direct OEM replacement for Goodman WFD195090S4CAB\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe 150°F calibration is specific to this furnace's plenum design and airflow.
