I have a Thermador SGCV36G gas cooktop. All four burners ignite properly (and immediately) but on two of the burners (back L and front R)the igniter continues to click (and spark) for 15 to 40 seconds even after the flame on the burner is lit. This seems to be temperature related -- if I turn the affected burner off once the clicking ceases and then immediately turn the burner on again it does not click repeatedly after ignition. However, once the burner is turned off and allowed to cool down the problem recurs. I've carefully cleaned around the igniter pins and also cleaned the burner caps (making sure all of the holes are patent). I've recently had the spark module replaced (when the old one failed suddenly none of the burners would light), but this is an issue preceding the installation of the new spark module, although it seemed to have temporarily resolved for a couple of days after the new spark module was installed. Any suggestions for problem solving? Many thanks -- David

I am having the same problem, I have the second bank of burners. front and rear, the burners light right away but the igniter continues to spark until the burners are turned off. this is Thermador PC486GE I have cleaned the area around the burner but whatever tells the igniter that the burner is lit is not sending that information back. This is the same on both burners in the bank, The other two banks of burners are working normally. what would make this happen?
