Daniel D Lancaster , CA September 06, 2016 Appliance: Model GDB307PDS09 The electronic control board failed (went dark) after putting the oven on clean mode (common problem with these models) Replaced ECB, remove the two screws on the outside bottom of side trim and remove side trim. Remove two small screws holding control panel. Carefully pull control panel forward to access four screws holding control board to control panel. Very carefully disconnect ribbon from control board by depressing side clips to release. Remove the four screws and move the control panel out of the way. The ribbon is permanently attached to control panel and may be brittle due to overheating, if broken you will need to replace the control panel also. Depress the keeper and slide the side electronic panel out of the ECB. Rotate ECB to access wires attached. It is now a simple unplug and remove and replace in reverse order 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
