Mine was (and I actually made a thread about it because it was so sad) plugging the kegerator into the wall instead of the temp control after cleaning it, causing my just kegged chocolate cherry stout (which was the biggest PITA to brew) to freeze. I corrected the plug issue, ramped up the PSI to see if I could push the icy sludge out of the faucet, but it was a no-go so I turned the PSI back down. I forgot to close the faucet though. The next morning I came into the garage to check on it and found 4.5 gallons of my hardest brew ever on the floor. Most expensive brew too I think.
