Whirlpool RBD305PDT14 blank display - beeps

[SIZE=2]Desperate for help - ‘closing’ on home being held up! Please help.

Display is blank - there is a light in ovens when door opens. Reset breaker several times but it only beeps twice- hesitates - beeps 5 times. No buttons work.

Do I need Touch pad & Control Panel ( 8300533) or the Oven Control Board (8301917)??[/SIZE]

Do you have instructions on how to take parts out or do I have to call repair man?
