Dennis S Scottsdale , AZ April 27, 2018 The left front burner on my glass top range burned out Replaced the element. It took about 1.5 hrs. to do the job. The instructions said to calibrate all the burners after an element has been replaced. I did not need to do this on my cooktop, everything worked fine. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
