I wouldn't do anything just yet.
It sounds like the control board is wet or damaged.
But Im betting on WET for now lol;-)
Open the door and run the oven for about 20 minutes 325 or so, with the door open. then turn it off. Next turn off the unit from the circuit power panel in your home please turn off the power to the oven for 30 full minutes then you can turn it back ON. Please let me knwo if that helped?
In any case, I will stick with you until this is complete.
