whirlpool control board replacement

This morning while laying in bed, I heard a series of beeps that came from my Whirlpool Double Oven…RBD305PDS14.
I went out to look at the oven and the display was not working…no error codes, no time, nothing…completely blank.

I have noticed that over the past couple of weeks the display being very faint when the oven is operating and then after it has been turned off for some time, the display goes back to being bright like normal.

After reading thru some of the forum posts, it seems as though my control board is fried (part number 8302319).

can you please confirm my suspicion…and more importantly provide some guidance as to how to replace the faulty control board?

Thanks,
