Shematic for Thermador gas stove model WCGG30

try cleaning the burner completely and make sure it is dry when done

This sounds like you may have to fix a problem in the pilot area before it will work. These gas operated devices have to meet a much higher safety standard than their electric counterparts. It is a built- in safety feature. Now, look for any obstruction or crimp in the gas line. My guess is you are not getting proper gas flow or pressure or the pilot could be physically blocked.

Hi,

this unit has a gas coil controling the valve . and wen it gets hot it is failing and cannot keep the gas on . replace the valve coil // mm

Clean the grease off the igniter; if that don't do it replace the spark module. Manual

I would say that pop was one of you igniters.  either that or the stove is not installed correctly and when it gets warm, thermal expansion makes the metal pop.  I would say that I would use caution and discontinue its use.  Most problems with these need to fixed professionally.

Most likely the oven will not work because the striker is not coming on. I am not very familiar with this stove but most thermador gas oven uses a electronic igniter. the switch controls both the igniter(striker) and safety solenoid so if neither the striker or solenoid is not powered up the switch may be the problem

theres a part in the cooktop called a spark modual. replace it. when i goes bad the problem your having is what it causes

Either the potentiors or the simmer control.

try a non abrasive cleaner like bartenders helper. it wont scratch and should help to tone down some scratch marks.
