E6 F2 on Whirlpool Double Oven

I am getting a E6 F2 error on my FRBD305PDB8 Whirlpool double oven. The unit will beep, shut down, then days beep and start up again and work fine. I called Whirlpool and they said it is either a control panel or controler unit.

Control Panel part number 4451973
Controler Part number 4451991

How can I determine which one is the problem and any advice on how to install the part?

You can find much more information about this problem in one of our previous thread: http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/1094-whirlpool-fault-code-e6-f2.html
