Buttons on control panel do not always work. Some work correctly, others not at all. Please advise solution

I have this oven, and had the same problem..only after a time it got worse..eventually all the buttons did not work. The problem is the keypad itself. It is very easy to change. Remove the 3 screws along the top of the oven. Then the vent pane will slide to the right. You will then see 1 screw holding the entire keypad assembly. Unscrew that, and the keypad will angle forward. There are 5 connections holding it..unhook all of them (you might need to, write on a piece of paper where they go)..BUT, you can try this first, reconnect the ribbon to the keypad by sliding the locking plastic up and then slide the ribbon out..then reinsert it back down as far as it will go. Push the locking plastic back down. Reverse the the screws back..and try it. If it works great, but it may not last. You can order just the keypad (here's the issue, it costs about $171) and replace it by removing the 4 screws holding the circuit board over it. The new pad just snaps into place, reattach the new ribbon. I think the problem is because the steam when cooking goes right to where the keypad is. My oven is over the range..so now I use the vent fan all the time..hope this helps. If you need better instructions..search YouTube with you GE model and the words replace keypad.
