Colleen S Mount Kisco , NY July 04, 2015 The stove top knob broke so i ordered several for when this happens again and it will The knobs break easily, but they are very easy to replace. I just slid the new knob into place. Make sure that the thin metal collar from the broken knob is off the shaft on which you will slide the new knob. The thin metal collar is there to reinforce the plastic part that slides over the shaft. Delivery of the knobs was quite prompt and the replacement is easy. 4 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
