Thermador SGC365R one burner keeps sparking

I have an older (1998) Thermador SGC365R cooktop and one of the burners (not XLO) keeps sparking after the flame comes on. I assume I need to replace the ignition/spark switch that is on the burner control knob. I'm looking for instructions on how to do that and how to dismantle the cooktop so I can replace the switch. thanks!

Welcome to the forums.

I'm just passing thru and will return shortly.

Question.... the burner that keeps sparking.... is it a burner that relights itself if the flame goes out ? That would be called a re-igniter. Sometimes available on one, several or all burners.

Which burner has the problem ?
If it was the switch on the gas knob..... it would usually be sparking continuously... even when turned off.

The burner that has the problem is not the XLO burner that cycles on and off for a simmer setting. I have two of those. The other three burners will reignite if the flame goes out. One of those three burners is the one that doesn't stop sparking after the flame is on.

The reignition module senses the flame thru rectification. It's important that the igniter be clean so that it can sense the flame. Try cleaning that first. If it doesn't help then the spark module may be defective.

Two questions.... what is the exact model for the range.... you left off a code letter.
Which burner is the problem one ?

I did the cleaning after reading through a few of the posts on this forum. I was hoping that was the problem but no luck.

The model no. is SGCS365R.
The problem burner is the one in the back row of three all the way to the right, just above the burner control knobs.
