If you have power TO the control board then chances are good that the board is the problem. I would take it off and into a shop to be tested. When I get to my computer later today I can get a copy of the Service Manual for you. I will be out on a Service Call for a bit and check back in later. All follow ups are included in fee.

You did check the main fuse in the load center? And it might be just a bad connection on the board. Unplug it and then plug it back in again. The board is located on the rear area or to the side of the water heater. Not large.......about 2" x 5" and has the red ignition cable attached. Let me know what you find and we can go from there.
