I have a viking over and under oven with a defective latch switch, how can I remove the plate covering that area, I have removed the oven door and all the screws above and below on this cover panel,but it still won't budge, are some of the screw's that I must remove behind the grill, or must I pull the oven out enough that maybe there are some attachment screws on the side wall. model DED0271.....asimburger@yahoo.com
