Keith M Garden Prairie , IL March 05, 2016 Power went out to the control board so that both ovens were down also one of the ovens had a crack on the inside glass of the upper oven I ordered a new control board with transformer. I was able to pull the oven part way out of the wall and by working from the top, was able to remove the metal access plate exposing the rear defective board. The rest was easy. The glass was accesses from the front, bottom screws and side screws. It was easily than I thought it would be. The delivery was extremely fast.
