The Frigidaire Gallery Range E14 Error means the user interface panel cable is missing or disconnected.
Check all the cables between the rotary control boards and the user interface board (UIB) and make sure the connections are tight and the cables are not damaged. Check the cables between the rotary board and pilot lamps and make sure all of them are connected properly.
If all the cables and connections look good replace the user interface board (UIB), if the problem persists afterwards also replace the rotary board.
To access the components listed above you will need to remove the control console on the range. The page linked below has instructions for doing that.
