This error message has come up a couple of times when I was using the stove top. It eventually comes back, but I want to know if it is dangerous. Can it be repaired, or do I just live with it?

 F11 error code means the keypad on the main control is shorted. The only thing you can do is try and reset the electronics by killing power to it at the breaker/fuse panel on your home for one full minute then restore power. If after that the problem persists the main control will need to be replaced. If you need the part number for the control board just post a new question and include your model number and I will look it up for you.
