Viking VDSC4874 left small oven won’t turn on when knob is on Bake

Would anyone know why the left small oven won’t turn on when knob is on Bake but will when the oven is on convection broil?

Also, the knob on the right griddle, or griddle thermostat was broken and now when I use the left griddle, it doesn’t heat to the right temperature.

can anyone help??
