Mounted on the heat-exchanger bulkhead, it senses supply-air temperature and opens the gas valve \/ ignition circuit if the furnace overheats — typically from a dirty filter, blocked ducts, or a failing blower. Unlike the manual rollout switch, this auto-reset limit closes again once the cabinet cools, allowing normal operation to resume.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eOEM Part Number: 20162903\u003c\/li\u003e\n\u003cli\u003eType: Primary high-limit switch\u003c\/li\u003e\n\u003cli\u003eTrip Temperature: 150°F (auto-reset)\u003c\/li\u003e\n\u003cli\u003eFits Model: VCES961005CNAA\u003c\/li\u003e\n\u003cli\u003eFunction: Heat-exchanger over-temperature protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe 150°F setpoint and mounting flange are specific to this furnace's heat-exchanger design.
