Clemencia R Anthem , AZ November 17, 2018 Appliance: Model GE PROFILE MICROWAVE Need to change microwave bulb on a GE Customer service was very good, as for instructions on how to do it. Thank you so much. By the way you don't need a certified GE person to do this job you just need the time and patients. To GE incredible that you can do a better product.
