I have a kenmore stacked washer/dryer. Not sure the model number as I am not at home right now. Anyway, as a casualty of moving I broke the knob/shaft off the washer cycle timer. How do I replace or repair this and how much does a new knob/assy cost roughly? Thanks for any help/advice...

I am sure you can order a new knob assembly from Sears. If you know your model number give them a call. The cost should be less than $10 for the knob.
