Stove/oven Range
 

When I turn the oven on, all of the electrodes(2 top and 1 bottom one) are sparking continuosly even after few minutes when oven is already on and hot.
Ceramic electrode was cleaned with sand paper and tooth brush and nothing changed- I relaced the spark module also but the oven stopped working so I put the old one back and the prevous situation happened again. Is it the spark switch oven that is broken? What can I do to stop that non-stop sparking?
Thank You
