Whirlpool oven E6 F2

Looking at some of the other posts I believe I have a pretty common problem, but need to verify which part I should replace.

I have a Whirlpool RBD305PDB12 (black) double oven. Last week the display went dark and the only thing that worked was the interior light. Once or twice a day I would hear a series of beeps (similar to what you hear when the oven is done pre-heating). Just today an "E6 F2" error appeared on the display. Ironically the oven magically works again… however I suspect not for long.

So, would this be an indication of a bad Control Board or Control Panel (or something else)? Is there anything else I should check?

Any advise would be appreciated before my wife get too used to going out to eat! :slight_smile:
