A limit switch in a furnace is a safety device that monitors the temperature inside the furnace. If the temperature exceeds a safe level, the limit switch automatically shuts off the furnace to prevent overheating and potential hazards like fires or carbon monoxide leaks. This helps ensure the safe operation of the heating system by preventing dangerous situations and protecting both the furnace and the occupants of the building.
