Burners no longer work

This morning all four burners on the cooktop stopped working. Both of the ovens seem to be working just fine. Just the burners.

I replaced the control panel in this unit a couple of years ago.

Is there a methodology I can use to diagnose what’s going on with the burners? I’m not getting any codes like I did when the control panel was going out.

EDIT: I guess I had it wrong, spouse says nothing is working, but the clock. Could this be the control panel again?

EDIT2: A little more information, the control panel seems to work fine. You can set a temperature for the ovens, and you hear the clicks like it’s setting things and whatnot. It’s just the ovens and burners on the cooktop don’t heat up.
