Don D Carlyle , IL July 22, 2016 Lightning strike destroyed my clock/timer unit of my gas range I ordered the part off line. It arrived in less than 24 hours even though I didn't request overnight delivery. I used a screw driver to remove the back of the stove and old part and replaced it with the new part. It took about 10 minutes. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
