Replaced the "Encoder Board". My GE Advantium control panel came of fairly easily. There was 2 screws on top to remove a vent director giving access to a single screw that held the control panel in place. Once I removed that screw, I had to slide the control panel upwards by about 1/2" before it came off. At this point, I took several photographs of the wire connections to make sure I could reassemble them correctly... there were many! After unplugging the wire harnesses and connections, I had to separate 2 main control boards that were attached by a series of copper pins (probably 22 or so). Finally, under the 2 control boards I was able to access and replace the Encoder Board. After putting everything back together, it worked like new. Since this part only lasted 2 years, I'm guessing that I will have to replace it several times over the life of the appliance.
