Just wanted to post a quick thank you to you guys, I was encountering the same issue and I had already hooked up the white from the timer to the white in the box. What turned out to be my problem was that I did not have the black from the timer connected to the group of black "line" wires. It appeared that I had them transposed. Thanks again to you guys this helped me get my timer working. I was about to take it back, thinking that the timer wasn't going to work for me.
I have the exact same timer and I read your (jbfan) reply and it is rigth on with the instructions. The problem I have is I have three switches in the same area and i am replacing one of them with the GE Digital Timer. There are three big wire nuts connecting 3-4 wires each, but none of them are white ! All the wires are black. I have the 2 black wires that are bound together and then the single black. I can connect the black on the timer ti the double black and the red to the singel black, but how can I locate the correct wire(s) for the white ??? I greatly appreciate your help.

The white wire connectes to all the whites, the two black wires connect to the black on the timer, and the red connects to the lone black, switch leg.
Green goes to bare grounds.
Are you sure about the red wire connecting to the neutral.
If you connect it like that, nothing will work because there is not a load wire.
Do you have a number to look up online.
