The oven door is locked and the element will not heat up. I checked the power going to the element and the door lock motor and there is not power going to either. I thought since there is not power going to two seperate items that it had to be the control board. I changed the control board and no change. I tried to unlock the door through the control panel and I can hear a click but the door still doesn't unlock. What is causing the door to remain locked and the element to not come on? Thanks for you help.
