Thermador WO16 questions

Am I flogging a dead horse? I've still got my Thermador WO 16A oven. It works great, but the little red light above the center knob is out. I miss the reassuring red glow when the oven is on! Does anyone have a spare or know of a schematic that says what the part is? I'm sure it's not unique to this oven... Also I need the little knob that is in the center of the clock! [email protected]
