How do I troubleshoot Thermador Masterpiece Wall Oven that has a Electronic Oven that has a Control Board that is too hot?

The temperature on the electronic oven control board was over 200 degrees. Make sure the oven door closes completely. If the upper oven door hinges are faulty, replace them. If the upper oven door seal is damaged, you have to replace it. The upper cooling fan wire harness connections need to be checked. If the wire harness is damaged, you can connect it or replace it. If the upper oven cooling fan doesn't work, you should replace it.
