GE Profile Wall Double Oven seems powerless

About a month ago, the oven control panel started freaking out and the oven lost temperature while I was cooking. I opened and shut the door and the screen started blinking all lights like crazy then the power completely died.

We tried a hard start at the fuse box.

We just replaced the control board and the relay board and still nothing.

We did have the door off to do the repair and put it back on…is there a safety switch? What else could be wrong?
