Kelly B Canyon Lake , CA August 23, 2015 Broken turner knob This was quite possibly the easiest fix I've ever done. I pulled off the old knobs (which, turns out, were aftermarket knobs), and simply lined up and pushed on the new knobs. I can now see the dial numbers on the cooktop, which I had never seen before! The new knobs look amazing! Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
