Where is fuse located?

Bottom element wouldn’t heat up. Broiler works fine. Ordered new baking element and install today but still won’t heat. Checked breaker and fine.
I keep reading about over heating fuse (can’t remember exact name) but where do I locate?
Maybe sensor? Fount it sticking out of left hand side of oven. Will test and order if need be.

This unit does not have a thermal fuse/cutoff.

If the unit shows that it is ready then it could be the oven sensor or the control board.

If the unit stays in preheat then odds are that the control board is shot.
