I have a Whirlpool Gold double electric wall oven (upper Convection) stainless/ black. Model#Model GBD277PDS09
Ser#XP4504175. I purchased it new in 10/11/03. As of late the oven has started beeping. I reset the breaker. panel shows PF. The clock will set however a padlock symbol appears and the word "Start" I then press the start button to find the clock will go out. If I press and hold the "Upper oven off" button a fault code of E6oNF2 appears. After reading several posts in your forum I am guessing I have an issue with the keypad, clock, membrane or control board. Or a combination with some or all the above. I have looked at it a little so far and the connection between the pad and control board looks in tact. I'm hoping you can help me out. Thanks.
