Oven won''t start. where the clock time was, it just stays off.

Maytag model # MGR5770ADB

Been having issues with the oven. Code F1 would keep popping up, when oven timer us used. Now, tried using the oven self clean, set the timer, then the oven shut itself off.

Now I can't start the oven or even set the clock, or nothing. The word "off" would pop up, where the clock time used to be, saying "off". I even tried unplugging the stove, over nite, hoping that I could reset it. But nothing is working, execpt the word "off" showing up where the clock time was. Even tried holding the cancell button down, or any button on the oven, nothing works.
