Oven does not work; everything else is fine

Can’t get oven to heat; burners and broiler work fine. Oven & Preheat lights come on but no heat. Any ideas???

Here are your parts.
You seem to be missing the last digit so you will have to choose a unit in the Matching Model Numbers section.

Here is your wiring diagram

Unplug the stove.
This is very important because on most units there is still voltage to one side of the element even when it is turned off.
Undo the screw/s holding the element to the back of the oven.
Carefully pull the element into the oven.
Remove the wires from it and check it with a meter.
Should be around 20 to 30 ohms.
It is a good idea to clip something (clothespin etc.) to the wires so they do not disappear into the back of the unit while you are checking the element.

If OK check the wiring from the control board to the elements.

If OK odds are that the control board is toast.
