GE Built-In Oven Control Panel - replace entire assembly or just control kit

I have a GE Built-In Oven (Model #JT910) that the Clear/Off button is not functioning. All other control buttons activate and work properly, including Clock, timers, Cooking Selections and temperature settings. When I push the Clear/Off button - nothing happens, ovens settings stay as is and no audible tone is heard. My question is do you think I need to replace the entire Touchpad and Control Panel Assembly (P/N AP2029580) or just the Electronic Oven Control/Clock kit (P/N AP2633043).

Thanks!

Note: getting tech info off the net is near impossible, GE likes to keep this a secret.
I would try the following cleaning/checking first.
Since I cannot provide pin-out info for the keypad it becomes difficult to check the keypad switches.
The likely culprit is the keypad/control panel but it is a bit of a crap shoot.

Connector Cleaning / Checking
Unplug the unit
Open it up
Remove the ribbon cable from the keypad to the control board at the control board.
Clean the edge connector.
If it is the type where there is not a connector just the insulation is removed, it can be cleaned with a pencil eraser. Do not use an ink eraser as it is too abrasive.
Check the tracks in the ribbon cable for hairline cracks. A magnifying glass helps here.
Would not hurt to clean the connector on the board. Use electronics contact cleaner or isopropyl alcohol and a tooth brush. Be gentle and do not reconnect till all the solvent evaporates.
Reconnect everything and give it a try.
