Mounted on the heat exchanger or supply plenum, this switch continuously monitors discharge air temperature and opens the circuit to shut down the burner if the furnace overheats — typically due to restricted airflow from a dirty filter, blocked ducting, or a failing blower. It automatically resets once temperatures return to a safe range, protecting the heat exchanger from thermal damage.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePart Number: 20162903\u003c\/li\u003e\n\u003cli\u003eType: Primary auto-reset high-limit switch\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 150°F\u003c\/li\u003e\n\u003cli\u003eBrand: Goodman (genuine OEM)\u003c\/li\u003e\n\u003cli\u003eFits: ACV90704CXBA and compatible furnace models\u003c\/li\u003e\n\u003cli\u003eApplication: Furnace high-limit overheat protection\u003c\/li\u003e\n\u003cli\u003eEquipment: Furnace\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe temperature setpoint and mounting bracket on a limit switch must match the furnace exactly.
