My thermador cook top (GGS30 / SGS30 ) has 4 burners.

THe 2 with XLo ( turn off & on) are not working. No spark, no gas.

I have looked at wiring diagrams, and i am guessing either the

SPARK MODULE ( AP3672547) or
GAS SIMMER CONTROLLER ( AP3672547 )

need to be replaced.

Has anyone else ever replaced either of these ?

Is it difficult ( special tools needed) ?

Thanks
Tom

Hello again ...

I tried to get the cooktop apart. There are some metal tabs which I had to bend straight, and this allowed the metal enclosure to be seperated from the glass top. This allowed me to look into the space, but it would not come apart. However, it looks like I need to disconnect all four (4) of the main burners with a nut accessible from the top. This looks to be a 19 or 20 mm metrics brass nut. I do not have this size. I did try to loosen a little with an adjustable wrench, however, they do not want to budge. ( I assume they are on really tight from the heat and all).

Does anyone have any suggestions as to how to get these nuts off so I can change the controller ?

Thanks in advance, Tom

Wow, drill them out. ( !?)

OK - I guess being that they are brass, that shouldn't be too difficult to do.

I assume I will need to buy 4 new ones then.

thanks for advice
Tom

So How did you make out?? I also have a Thermador gas cook top about 18 years old now. When you turn the burner on , only get gas and no spark. I suspect the spark module. Is there any way of testing it first??

The model # is GG 30. The first burner turned on will not spark , nor will any subsequent burner try igniting. Only gas flows. I have manualy lit one burner and then tried turing another burner on and it still will not spark.
