Disclosed is an automatic ice making machine having an ice making section with an evaporator connected to a freezing system, a water feed system, an ice releasing unit, and a temperature detector which detects the temperature of the water to be frozen circulated through the water feed system; characterized in that said ice making machine further comprises a protection unit which stops the ice making operation after a predetermined time counted from the starting point of the ice releasing operation, if the temperature of the water to be frozen does not drop below a predetermined level. The automatic ice making machine may have a water level detector for detecting the level of water in a water tank instead of the temperature detector, and a protection unit which stops the ice making operation when the level of the water in the tank of the water feed system does not drop below the predetermined level within a predetermined time counted from the starting point of the ice making operation. These protection unit may have an alarm means which is actuated when the ice making operation is suspended or a means for releasing the protection manually.
