Frigidaire Oven won't heat

The oven suddenly stopped heating yesterday. Broiler won’t work, neither will the bottom element.
Speed bake and oven light work fine.
Thinking it’s the electronic oven controller, but hoping it might be something else.

How hard/easy is it to replace the EOC (if that’s the problem)?
Thanks everyone for your help.

Speed bake and oven light work fine.
Are you saying that the elements heat up when in speed bake.

If the above is yes then the control board is probably shot.

Do the stove top elements work?
If not you probably have a power problem.
