Whirlpool Accubake Duo Oven Not Heating up

Question

I have a Whirlpool Accubake Duo oven that is not working.  The gas is being distributed to the burners, but not the oven.  The display panel works correctly and allows me to set the baking temperature and time.  However, after leaving the meal in the oven for 30 minutes, I realized the oven was not heating up. We have checked to make sure the oven panel was not locked.  Any assistance would be greatly appreciated.
