Old Thermador cooktop continues to spark even after turned off

Could be the igniter isn't sparking, sometimes they get cracked and run to earth you will still hear it click. Remove the top plate and check the wiring and igniters, turn the lights off and you will see if it's sparking all over the place.

I have the same range top. I am looking for the switch assembly. Do you know where I can buy this part? Please email me if you do. [email protected]

Clean the grease off the igniter; if that don't do it replace the spark module. Manual

I don't have a Thermador cooktop but here is ma taught.

Could you unplug the two faulty igniters and see if problem remained

Could you plug one of the faulty igniter at the location of a good one. The goal is to isolate the problem. Is it the igniter or the electronic board.

Faulty ground problem may occur also after an spillover on the stove. In that case, use a cotton swab dipped in scrubbing alcool and clean the spark area on the igniter and the burner.

Good luck

I have a Thermador Gas Range PG364GDBS - Oven, 4 burners, and center griddle. All are gas. The four burners and gas oven work fine. The griddle just stopped working, no spark. Turning on the griddle control, the gas valve opens(hear it), gas flows (smell it), but the ignitor will not spark (no loud or faint spark that I can hear). I got a replacement ignition device (mount at the burner) thinking it might be the problem, but still no spark. I checked the AC voltage at the terminal and measured 39 VAC between the terminal and ground. Not sure if that is the correct voltage. Any insights or advice would be great.

Turn the knob back towards off about 1/8 of a turn and you will take it off lite and it should fix it.

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.

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