Great, thank You first. A gexl44 oven. The control board wb27t10083 does not respond to the bake or up/down arrows. No error codes. Unplugged 5 wire plug in contact on the back of the control board, cleaned and no change. Feels like the three buttons bake, arrow up and arrow down have just been over pushed in operation. Unsure if the contact to the responding part of the button is happening.
sp2do it does sound like a bad control board. Take a further look at the manual for the oven and see if you can troubleshoot it accordingly. ManualsLib - Makes it easy to find manuals online! You can check the button connectors etc. with a multimeter.
