Help! Any appliance engineers around here?

Since only your display is out, I think you fried something on the controls board. My display went on my wall oven. Cost me $85 to have them tell me what I suspected which was the control board. They wanted $340 for the board and another $85 to install it after they got it in. I got it for $240 and installed it myself. Had to figure out how to take the oven apart and then had to disconnect about 15 connections. Good thing I labelled them so I could reconnect them. Make sure you flip the breaker for the oven before you start taking it apart.
Good luck
