Broiler stays ON

I have a kitchenaid modelkebc208kss02 and serial number xp4301534 double wall unit ovens.
The broiler stays on no matter what temp it is set on.But before that we did have a thunder storm and the doors locked up and the start time ? appered on the screen and the clock didn’t stay on.
I turned off the breaker for 30 min and now the clock stays on but the broiler stays on when cooking and will burn the food

what can I do?

The following should also help.
Whirlpool KAC-49 27 & 30 inch Electric Built-In Double Oven Service Manual - ApplianceDigest.com
You have to join the site to download the manual but it is free and this is a very good site for manuals and other info for the appliance repair DIYer.

If the element comes on full and reaches ready state then odds are that the control board (Item 3 in Section 1) is shot.
