Jolene P Stevenson Ranch , CA April 10, 2015 Many things need to be improved I was cleaning my cook top and had put the knobs in the water to clean them. I forgot to take one out. Turned on my garbage disposer and you know what happened to that knob. The cook top is 17 years old. Never thought I would find a match. Well, I went to Appliance Parts Pro and a nice guy helped me order. One of my cook top pans was getting scratched from all the cleaning. They had that too and also a new grate. Now my cook top looks like new and spent less than $150.00 I couldn't be more pleased. 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
