Mounted on the heat exchanger or blower deck, this snap-disc safety control continuously monitors furnace temperature and opens the ignition\/gas valve circuit if the unit overheats — protecting the heat exchanger from cracking and preventing a fire hazard.\u003c\/p\u003e\u003cp\u003eA failed limit switch is a common cause of a furnace that short-cycles, blows cool air, or locks out on a limit fault.

Generic limits with different set points can trip early (frequent shutdowns) or trip late (bypassing critical overheat protection).
