Brand: Thermador
Model Number: PCG366G / 16
Main Symptom: Igniter clicking
What happens & when: It wont stop clicking after lighting. Clean the igniter ceramic portion. Works fine all day of cooking. Next day the same problem returns. Clean igniter and repeat the problem almost every day
Error Code (if any):

Has the burner head and cap been removed then thoroughly cleaned, along with the cooktop panel that they sit on? It sounds like there is not a proper ground which is commonly caused by residue accumulating in between the igniter and the pathway through to the cooktop panel.
Only part I can see to remove is the burner head cover. Some other web searches indicate a part behind the burner knob may be dirty or need to be replaced. Another odd detail is that after I clean the igniter in the morning so it works without continuously clicking, when you do use the burner throughout the day and turning it off, within 10-15 seconds the igniter will fire off 1-2 times.
Is the continuous clicking occurring after a flame is ignited, or is it occurring when the burner is off? It looks like this would be the burner with a venturi tube. The hexagon in the center would be used to remove the venturi to allow the burner head to be removed.
Continuous after and while the flame is present. I’m waiting on the repair manual from Thermador (they keep them hidden and require a formal request). Is you thought that i’d need to remove the venturi and then inspect the wiring below the igniter or is there a chance I need to order a replacement igniter modual?
The video may not have sound but the 1st burner is clicking while the flame in on and the other stops clicking as soon as the flame is lit
I believe there may be an issue either with the spark module not sensing the current properly when the igniter sparks, or there is residue that has accumulated under the burner head that is causing an increased resistance and not allowing the current to register properly. If removing the venturi and thoroughly cleaning the top panel and burner head does not correct the issue, the spark module for that burner would be the likely cause of failure. The attached image is what voltages should be found when the burner is set to high, with the exception of the electrode voltage. Here is a link to our information page for the spark module.

Outstanding, i’ll try cleaning underneath and it that doesn’t correct it will order the spark unit.
-each burner has it’s own spark unit?
-would you know the size of the hex on the venturi to unscrew it?
Unfortunately, I do not see the size it would be. However, it does look like it is about the size of a spark plug wrench for a mower. I believe that is about 3/4".
it was a 5/8" hex. Think you for all your advice, removing the venturi i discovered that there is a spring device below the spark electrode that was stuck and not allowing for constant contact and my guess of not completing the circuit or grounding. I got the spring device to function and make constant contact with the electrode and that seems to have fixed it. We’ll monitor. Awesome support!
