SOURCE: Thermador Gas Cooktop Won't Stop Clicking : SGC304RS

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

SOURCE: Clogged burner on gas cooktop

lowly is it the left burners that won't lite? I only ask as depending on the model some of the Thermador cook tops had simmer control burners. This is a 3 part system on the burners. 1 a simmer control, 2 electric solenoid, 3 potentiors. When you turn on the burner the potentior tells the simmer control to send power to the gas solenoid. At the same time the unit will spark. If your unit has extra low on the left 2 burners then you have this system. The usual problem in the potentior. Hope this helps.

do not drill out the jets they will not work properly.
I would check all your documentation you may have the convention kit with your owners manual or it may be attached to the oven.

SOURCE: Cleaning Thermador Cooktop?

To clean the stainless around the star burners try applying Easy-Off oven cleaner around the stars with a Q-tip (spray the cleaner onto the stainless surface first because it's very hard to control the spray output). The cleaner will make your stainless sparkle and the Q-tips allow you to get close enough while controlling the application. Scrub gently with the Q-tip and the stains will disappear within minutes. Wash thoroughly with a wet cloth. I've used this on my older model Thermador stainless cooktop for 5 years.
