Ice maker not working

I have a Kenmore 106.52569100 side by side refrigerator and the ice maker is no longer making ice and I no longer hear the water run for it to make ice. If I put ice in the bin it will dispense if I hit the lever outside the door. The water on the front of the frig works fine. I looked at some of the previous threads and if I open the freezer door and push the lever in on the left side the light on the right hand side does not light up or flash. I tried reversing the plugs on the back of the frig, and when I switch the purple plug for the water to the green valve I get water to the ice dispenser and it runs down the inside of the freezer. When I take the larger white plug and move it to the purple valve for the water dispenser, nothing happens. Any suggestions?
