Diagnosis
F2 is a main control board communication fault. The board isn't talking to the touch panel or other components correctly.
How to Fix It
Perform a main reset. Unplug the range from the wall for 5 minutes. Plug it back in. This forces a full reboot of the main control board. The error may clear.
If That Didn't Work
The main control board itself is likely faulty and needs replacement. This is a common failure point. The board is located behind the rear access panel and console.
Heads Up
F2 is a hard error. You cannot bypass it. Repeated resets that temporarily clear it confirm a failing board. Replacement requires disconnecting many wire harnesses. Label them.
