The dryer was showing an F1 error code. I called AppliancePartsPros and spoke with one of their customer service techs. She diagnosed the problem and said I needed to place the main control board. They sent the part and it took about 30 minutes to install the board. End result - the dryer is back up and working again. 65 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
