Scott P Tipton , IA June 27, 2014 Dryer would not function could not enter diagnostic mode Initially displayed "30", would not change and no response from control panel button inputs. At one point, the display changed to "12" after a power off and the dryer did function again for a short period of time. It's now working good with a new control panel. 9 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
