Whirlpool Oven

I have a Whirlpool gold oven which is less than 2 years old. The touch pad went crazy on us and I was told to replace the control panel. I replaced it and nothing changed. I was then told to replace the touch pad. I replaced it and everything works but the bake button and the cook time buttons. I’ve called Whirlpool which did not help.
Can anyone help me? I’ve put $300 dollars into a $980 stove. It’s the last whirlpool anything I’ll buy.

Which connections? On the control panel hookup? Is there anywhere else I should be checking?
Thanks for the reply.
