Stove top works great still, but oven doesn't after replacing oven bulb. Think b/f ring hit metal part when he reached in to take off bulb dome and heard pop noise. Thought he had unplugged it but apparently it wasn't pulled away far enough and still had minor contact with outlet(I know, that's all it needs). No more oven working. The digital clock/timer does not work anymore either. Easy to fix? If so, how?
