I thought I should have both element wires showing 120 volts when the bake or broil buttom was pushed .[/COLOR]
I am assuming that you are using Neutral/ground as a reference point. This can get a bit confusing when checking the element circuit as it does not use Neutral. It is a L1 to L2 circuit.
One side of the elements are often always connected to one side of the line so you will see 120 at the elements even when the oven is off.
Then the bake and broil relays switch in the other side of the line to put 240 volts across the element.
I think this is how your unit is wired.
I am not 100%sure on this as some units have a DLB relay that kills power to L2 side of the line for both elements. I cannot see it the control board has this third relay.

In the wiring diagram you will see a Double High Limit Switch (item 7 in section 02 of the parts). Unplug the unit and check both sides of this. They should both be 0 ohms.
[COLOR="Blue"]If open it needs replacing unless it is the resettable type which pops a little button out on the back of it.[/COLOR]
Check that the fan runs OK.
It could also be that the control board caused it to blow.
Self clean cycles are also know to blow these.
If open I would also check the oven sensor just in case it cause tehe unit to overheat. It should be about 1,100 ohms at room temperature.

If the display shows that the oven is ready then it could be the oven sensor.
If the unit stays in preheat then the oven sensor is probably OK
Always a possibility that the control board is bad.
