Hi! My Kenmore oven is in trouble. Last week as I was cooking on the stove top and baking in the oven, I saw a flash of red light towards the left rear of the stove top, heard a lot pop and the whole stove went dead. Since then my husband has gotten the burners working. Upon examination, nothing seems to be burned out or damaged in any other way. I just can't get any heat in the oven. Do you know what could be wrong? Thanks for your help.
