How to fix a TurboChef TORNADO 2 Oven when the thermocouple reads an incorrect temperature?

If your TurboChef oven displays an incorrect temperature due to a thermocouple issue, follow these steps: 1. Check the connection of the thermocouple on the I/O control board. 2. If the connection is good, use an ohmmeter to check if the thermocouple is an open circuit. The cook cavity thermocouple should measure about 4-5 ohms, and the IR thermocouple should measure about 30-40 ohms. Measure at the I/O control board 40-pin connector. 3. If the thermocouple indicates an open circuit, replace the defective thermocouple. If the thermocouple is OK, replace the I/O control board.
