I found an instructional video on removing the knob. Found that only the knob end of the clutch (interlocking teeth) was stripped, so I ordered a new knob from AppliancePartsPro.com and cleaned the plastic debris from the timer end teeth. The knob arrived the NEXT DAY! The new clip that came with it was better quality than the original, the knob was a perfect fit and reassembly was a snap. Best of all, my wife thinks I'm a hero! Thanks AppliancePartsPro.com!
