I was using it this morning and at noon I tried to turn it on and it didn't. When it is off (plugged in) there is a green 4 lit up. When I press the power button, the 4 and the 1start blinking (green) and the fan turns on, but after 7 seconds it turn off and the green 4 lights up again. This has been happwning to me for about a week now, but it always turn on after a while. Can anyone help please?
-Thanks
