Whirlpool dbl oven

After going completely blank with the ovens completely non-functional aside from the interior light, a series of beeps occurred, then the display panel read E6 F2. After a period of time, the beeps re-occurred, then the oven was functional for a couple of hours. Since, the cycle has been repeating. Any ideas?
I got into the panel, disconnected a couple connections, tried a gentle swabbing with rubbing alcohol, and reconnected. No change.
Suppose I need to order a part, hmmm?
