I followed the diagnostic videos on the appliance part pro web site and narrowed the problem down to the gas valve. I ordered the new valve on Monday and received the part Tuesday. I installed that night and everything has worked great since. Just follow the help videos to determine what is wrong and the repair is really simple. Swapping the part was quick, but I did spend some time figuring out the problem. So my time estimate below is just for the actual part swap, not including the diagnostics.
