Tried all the various internet tips for unlocking the oven door but no help. Want to get access to control board and locking mechanism but after removing all the screws that seem to be holding the panel I could still not pull it out. After removing the end caps on the panel and trying to peer inside, I do not see any way to get in back of the panel without pulling the entire unit out at least several inches. Should I be able to get access without pulling the unit out? Thanks!
