JennAir JDS9860BDS Range 'Bake' button issue

My JennAir JDS9860BDS Range is having an issue where the ‘Bake’ button does not always respond. If I turn the main breaker off and back on the button starts working again. Trying to work out whether it is the Control Panel Touchpad (where the physical ‘Bake’ button is) or the Electronic Control Board itself that is the issue. It has been doing this as the humidity here in Maine has got pretty bad in the last week or two.
Any thoughts? (It looks like I can get either the Control Panel with Touchpad, or the Electronic Control Board as parts)
