Kitchenaid Superba - No HEAT

My Kitchenaid double wall oven all of a sudden won’t get hot. The control panel lets me enter all the commands as I normally would, but neither oven gets hot. I have tried convection and broil as well and the elements simply don’t turn on.

I have turned the breaker on and off a couple of times and that had no effect.

I have also read about issues with the thermal fuse after having run a self clean cycle, but I have not run this cycle lately (in fact I have only ever run this cycle twice in the 5 years I have owned the ovens.

Before I start to tear this thing apart I want to be sure that I’m choosing a logical course of action.

Any help would be greatly appreciated.
