Display panel works, but oven will not come on

I take it the oven will not heat. there is a safety thermo inside the grilles. it can be reset.. turn the power off at the breaker... remove the grille..inside of the door. then look inside the thermo is has two wires going to it and a red button in the middle.. push the red button down it will reset the thermo with a click... replace grille and restore power... hope it helps.. replace grille
