Arnise R Brooklyn Park , MN May 21, 2017 Replaced the timer on my dryer and replaced the knob I'm so excited that I got to do this all by myself. I had to remove the back cover from the dryer, remove the old timer and replace it with the new one. The knob had broken and I had been using pliers to operate the dryer. I thought I could do that until I got a new knob. Bad idea! This damaged the timer causing me to have to get a new one. The repair was simple and very easy thanks to the appliance part pros YouTube video! Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
