We were told by the applicance store where we bought our oven that the control panel was out. After 3 months of them not being able to get one in off back order, I ordered one off the internet. Now I can't figure out how to get to it to replace it. I'm not sure how to take off the front of the oven. I've removed the side black strips and can't see how to remove the touch panel from the front of the oven. Can you help?
