Top oven inoperative. Botton oven worked as designed.

First I removed the 2 screws that secured tht top front panel to the oven assembly. I then removed the decorative glass front panel. This exposed the 4 control unit mounting screws. After removing mounting screws and the control module I unplugged the wiring connectors and re-instaled them onto the new control. I replaced the module and reassembled the oven front. When I then tested the oven all of the oven units worked properly.
