摘要： A control method includes receiving an output value from an optical sensor to determine whether an ice bank is full of ice, driving the sensor heater for a first drive time to heat the optical sensor upon determining that the ice bank is full of ice, driving the optical sensor to receive an output value from the optical sensor after lapse of the first drive time, comparing the output value with the output value received to determine whether the ice bank is full of ice to calculate variation of the output value, and driving the sensor heater for a second drive time to heat the optical sensor so that the optical sensor is defrosted if the calculated variation of the output value is equal to or greater than a reference variation.
