If the furnace overheats, the limit switch opens the circuit and shuts the burner off to prevent damage. A failed limit switch can cause the furnace to shut off prematurely, fail to ignite, or run continuously. Replacing a worn or faulty limit switch is a straightforward repair that restores normal furnace operation.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation\u003c\/h3\u003e\n\u003cp\u003eDisconnect power to the furnace before servicing.
