Here are your parts
Replacement parts for WHIRLPOOL RBD305PDB14 30" Built - in Electric Double Oven Std - Clean Lower Self - Clean Upper |

Here is the tech sheet

Here is a manual (I think). I tried to download it with no luck, looks like the site is down for a while

Unfortunately it sounds like a bad control board.

I would check the voltage to the power transformer.
Also check the voltage out it's secondary. Do this with the board connected and disconnected, just in case the board is pulling the supply down.
I seem to recall that it should be 28 volts but am not 100% sure about this.

Would also try the following but it is a bit of a long shot
Connector Cleaning / Checking
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Reconnect everything and give it a try.
