I got the parts in two days. Replaced the timer and knob in very quick fashion. This is an easy job. I suggest you take a picture of your timer in place before you disconnect it. Then remove one wire at a time from the old timer and attach it to the new timer in the same place. 16 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
