Mounted on the heat exchanger\/blower housing, this normally-closed switch monitors supply-air temperature and shuts off the gas valve if the furnace overheats — a critical protection against heat-exchanger damage and fire.\u003c\/p\u003e\u003cp\u003eA failed or nuisance-tripping limit switch causes short cycling, no-heat conditions, or a furnace that runs the blower continuously.
