I have an electrically operated device whose purpose is to emit trillions of negative ions. When it is on it shows an orange light and you can feel a slight breeze coming from the negative ion emitters. However, it is not working now. The orange light will not come on when it is switched on and I can't feel the breeze. I have tried changing the 3 amp fuse. There is a switch in the cable. Does anyone have any ideas as to why it's not working?
