I replaced the front control panel. 4 Philips head screws to remove oven from the wall 12 inches. Used socket set to remove 4 small screws on each side that held panel. Pulled up on two black tabs holding thin flat clear connectors. Removed flat connectors from message board. Used same size socket to remove 4 screws separateing control panel from the silver bracket holding the message board. Replaced everything in reverse order.
