How do I troubleshoot Thermador Masterpiece Wall Oven that is displaying E101 or E104 error code?

Plug in the electrical power to the oven. Check the temperature sensor wire harness. If the wire harness is damaged, you can connect it or replace it. The upper oven temperature sensor resistance can be checked using a multimeter. At 70 degrees, you should be able to measure 1,080 ohms of resistance. If resistance is off, replace the oven temperature sensor. The electronic oven control board needs to be replaced if the sensor resistance and wire harness are not okay.
