kenmore elite gas stove error code F11

I just replaced the clock/timer electronic display and plugged the stove back in and keep getting a F11 error code. What does this mean?

Hello.

Disconnect the ribbon from the control panel and clean it using pencil eraser. then carefully reconnect it. if the F11 is still there most likely it’s the control panel.

The panel AP3910768
