I had the same problem after cleaning. I changed fuses and pulled the rubber buttons. Nothing .. THEN I unscrewed the bottom screws to allow me to get deeper inside. Discovered there are THREE connections that come from the front to the back of the machine and ANY of them may come unattached during cleaning. You may have to pull the entire master unit out to inspect, and that will disconnect these wire. Look at it. Then slowly put it back together. If you have small hands, it will help you reach inside to reconnect two. The main one to watch is the green-covered wire from the area of the power buttons, Be sure it is connected at the left rear, right at the point where the filter pushes down on one of the metal prongs. Mine works fine now.

WHAT AMP FUSE DO I NEED FOR THE ECOGUEST BREEZE AT?

I had the same problem. I took it to my sales representative because I knew he had seen quite a few of these machines. Sure enough, in a few minutes he had it fixed. What he did was to adjust the rubber control buttons on the right side of the machine. He took his fingers and pulled slightly on each of the buttons. He said that sometimes one will become stuck depressed and that will prevent the machine from turning on. You might give this a try.

The unit does not light up or don't turn on replaced fuse still no lights

Just wanted to make sure you inserted the carbon filter on the back before turning it on. It will not turn on without the filter in place. Also, you have to make sure the on/off switch on the back is turned on. Hope that might help.
