• The device does not have any switch. It turns on automatically when the power cable is connected to a 120 volt AC supply. It has a power rating of 710 Watts.
• The current passes through the heat switch before going through the two heating elements.
• Both the green and orange LED light up when the device is working. However, the heat switch opens if the temperature becomes very high (exceeds 165 degree Celsius).
• Therefore, current stops flowing through the heating elements to prevent any accident.
• When the fuse melts, only the orange LED will remain on , indicating that the heating elements have been shut off.
