By the way, the Capacitor is about the size of a nickel, on the GCIO vertical board, near the reset. We turned off the main line, removed board (two bolts, gently rock and pull, easy to detach from the larger board) and bled off the cap with a coin shorting the pins on the back. Read 0 volts (digital meter) and reinstalled board. Not sure if that was helpful or necessary on my call, but just recording the info here for any future searches.
