This is a Jenn-Air double oven. Turned off circuit breaker to the oven. Removed 7 screws that hold the top panel in place. Removed 3 cable/connectors from the clock module so panel can be removed from oven and placed on a table. Unscrew 4 hex head screws attaching clock module to front panel. Press on two tabs and remove circuit board from plastic frame. Replace with new board reversing dis-assembly sequence.
After examining the old board I discovered that the 470 microfarad aluminum electrolytic capacitor (in the corner) was badly deformed. I replaced this. Now I have a spare board. I believe that the failure (common in Jenn-Air ovens) starts with a transient on the power line (it did with mine). This damages the capacitor which progressively gets worse. This capacitor probably acts as a low pass filter on the power supply for the display. If any of you are into electronics, I would suggest wiring a zener diode across the capacitor to suppress transients. I wish the Jenn-Air engineers had put this in the design. It would have avoided a lot of costly repairs and saved them the bad reputation that they have as a result of this board failing over and over again.
