Broiler not working and won't self clean

What brand is this unit? Does the unit bake? It it does bake but not broil, you very likely have a bad broil element. If the bake and broil element both are not working then its sounds like like you may have another issue. Possibly the control board or damaged wiring to your element. It would be unlikely to have both elements out, but it is possible. I would check your element with your meter and see if its bad. If It is good then we need to see if we are getting proper voltage to the element. You should get 240 V. Let me know what you find out.
