Samantha P Cave Creek , AZ November 17, 2020 Timer stem was stripped and knob would not work. I watched several videos on how to replace the timer and decided to try it myself and save 200.00. I am so glad I took a picture first of the wiring set up! All in all it was easy and fast. Everything works great now! :) 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
