Next step, Control panel or keypad replacement?

We installed a double oven and E1 and F2 came up. The touchpad is not responding at all.
After reading the blogs posted previously, we figured out what E1 and F2 means, but upon opening up control panel to check for "firm keypad connector connection", we can’t find where that connection is located to check.

Also, if the recommended repair procedures suggest replacing "keypad", do we have to replace the whole control panel?

Here is your parts breakdown

The connection you want to check/clean is the ribbon cable between Items 1 and 3 in the Control Panel

And here is the tech sheet

If we cleaned/checked the ribbon cable and still no change, what part should we get? Is there something else we need to check?:rolleyes:
