Nancy C Tampa , FL February 08, 2016 I have a duet whirlpool dryer it is 10 years old the front display panel kept coming off and on error code pf I went on line to You Tube and saw how to take front panel off and thought that is easy enough. I then called your help line and described the problem to one of your techs and he confirmed what I thought. I needed a new computer board/control board. He told me if that is not the problem Appliance pro will take back part for up to one year of purchase. I thought I might as well try. I placed order and the very next day (Saturday) it was delivered. I took off the top of dryer then was able to get inside and remove the front control board. It was easy! By the way I am a women and my first time trying to fix an appliance! I Dryer works like a champ! I easily saved my self 2 service calls one to diagnose the machine and then come back and replace part. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
