Sadly, GE does not make individual parts available for these controllers, so they cannot be repaired.
You have to replace the control panel sub-assembly (part number WB07X10733 in your case) and the best price I've found on that is $370.32 here
(compared to $483.25 direct from GE).
In my opinion, this does not do much to inspire brand loyalty...
Or you may be able to find a whole oven on eBay for about that or less.
