Hey, I had about the same problem. While working on a stacked unit the control panel kept dropping off and hanging by the wires. Then I found 8 of them had pulled loose when I went to put it back together and I also can tell from the wiring diagram which wire goes where.
How did you solve it?

I am not sure what the problem is.

Could you be more specific as to what the problem is reading the wiring diagram?
It is really the only info available on how to hook up the wires.
