Camille K Alameda , CA June 15, 2019 Dryer timer knob would not turn With the help of the instructional video, my husband was able to replace broken timer mechanism in about 20 minutes. The hardest part was accessing the 3 screws in the back of the machine. Not a lot of space to pull the dryer away from the wall. Fortunately we have a pair of very short screw drivers that fit in the limited space behind the dryer. Works fine now. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
