William C Stevensville , MD January 28, 2017 Wouldn't change cycles Replaced timer, ordered part 1 pm and received it at 9:30 am next morning. your short film was plenty to show me how to change it. my big problem was getting the knob off old timer... I didn't know the center disk on front of knob popped off. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
