Carlos P Okeechobee , FL September 05, 2014 The timer knob had cracked where it slides on to the timer control Bought the replacement timer knob and changed the old one out. I noticed that the replacement knob had a metal sleeve around the piece that slips on to the timer. This must have been a problem with these timer knobs in the past. My thanks to the person that thought about putting the sleeve on to prevent cracking in the future. 36 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
