Hi Bostic,
You should have 240v at the two wires leading to the element vs. 120v. To me, the control board sounds suspect.

Verify that you are indeed getting 240v at the terminal block on the oven and not just the wall. This will rule out a bad plug & terminal block.

Next, you'll need to take your voltage reading directly from the board (at the pins specified on your schematic) you're looking for 240v there. This way you can rule out any thermal fuses, cutoffs, and the like that may be causing you issues. However, the fact that you're getting 1/2 the power to the terminals points towards the fact that your fuses appear to be good.
If you're not comfortable working with 240v and reading a schematic, I would recommend calling someone who is.

Remove power from the unit and check the high temp Cut-off (item 540 in section 02). It should be 0 ohms.

Looks like it is the resettable type (push in the red button).

With the unit UNPLUGGED inspect your control board markings.
On your board - you should have a bake L1 & L2 terminals. Usually they're going to be the same color as what's going to your bake element.

Once you've located the bake L1 & L2 you will need to take a voltage reading of these 2 while the oven is turned on and in bake.

Proceed with extreme caution:
With the unit plugged in, the bake turned on
Set your meter to volt reading
Be careful not to touch anything but your meter probes. (Don't let your fingers touch the metal portion of the probe)
Place one probe on L1
Place the other probe on L2

Your reading should be 240v. If not, it's a bad board.

Let us know what you find.
