    Abstract: A steam generator and a control method thereof are disclosed. The control method includes supplying water to a first chamber (C1), turning a heater (83) on, wherein power is supplied to the heater (83) to heat the heater (83) at a third temperature so as to generate steam, preventing overheating, wherein power supplied to the heater is cut at a first temperature so as to prevent overheating of the heater, and determining scale, wherein power supplied to the heater (83) is cut at a second temperature lower than the first temperature and then is resupplied after a predetermined time so as to prevent malfunction of the overheating prevention, wherein, when a time interval for the temperature of the heater to rise from the third temperature to the first temperature is within a predetermined time, determining scale is not performed.
