Service Manual for Thermador Pro Grand Dual Fuel Ranges:
6. First make a note of how the wires are connected to the solenoid
valve terminals, and then remove the wires from the terminals.
NOTE: It is always recommended to label and tag all wires, wire
connectors and harnesses prior to disconnecting them, so as to
correctly identify their connections/locations when re-assembling.
Alternatively, you can photograph the wire connections prior to
disconnecting (for example, with your mobile phone).
7. Use an adjustable wrench to unscrew the large hex nut on the
solenoid and remove the solenoid valve from the XLO valve. Be
careful not to lose the plastic O ring positioned inside the large
hex nut of the solenoid valve, as it may fall out easily
(see Figure 79).
8. Use a 1/4 inch nut driver or a 1/4 inch socket wrench/ratchet to
remove and retain the valve screw (that secures the XLO valve
onto the manifold) by accessing it from under the chassis base,
through the corresponding access hole. The oven door must be
opened or removed (see Figure 75 and Figure 76). Be careful not
to lose the rubber washer attached to the screw.

9. Gently lift the protruding part of the XLO valve out of the
receptacle on the manifold (don't lose the red rubber washer
attached to the XLO valve), and slightly bring out the (connected)
XLO valve–-potentiometer assembly from under the front panel.
