Constant ignition The two burners on the left side of the cooktop suddenly started to ignite non-stop. The only way to stop it was to kill the power. Knobs are not in the wrong place. The right side is working perfectly.

Hello Sharon,
are the two left hand burners "simmer burners" that low come on and go off to simmer a pot?
and the right side just set on and turn off without the simmer option?

if yes this pretty much describes your cooktop the part called the potentiometer is going the be the problem.

YOU HAVE a shorted ign sw. some of these only came in a wire harnes of 4 . and if they don't change all four when in there .. mm hope this helped .. feed back pls ..

Hi,
Here is a tip that I wrote that will help figure out why the burner spark keeps on clicking...

You're gas burner has an electronic ignition that you're hearing. Sometimes they can get gunked up and become sticky. If you have been using the stovetop regularly and this problem suddenly appeared, we can assume that the power grounding and polarity are correct. If this is all true, then an igniter or igniters are either wet or dirty. Unplug the electricity and thoroughly clean the burner pieces and specifically the igniters (little separate cylinder next to each burner) with a sponge or other non-abrasive dishrag and hot soapy water. Make sure all the burners and igniters are completley dry, plug unit back into electric outlet. If problem persists,call an authorized repair person as you may need 1 or more igniters replaced.
Good luck

Hi JHMcdona

Most likely the electrode for the right burner is defective. As well as the switch may also be defective (is shorted because of pressing hard on it trying to make it work!!). Change the electrode and igniter switch of the right front burner.

Regards

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

My Dacor cooktop had a similar problem of continuously clicking igniters. I unplugged it a couple months ago and used a piezoelectric igniter to get it started. Then I looked in the Dacor FAQ and it said to clean the ceramic igniter posts with alcohol not water. I had to scrape some gunk off a couple of the posts with a knife before cleaning with alcohol. Now it works.'

I think the igniters use electrical conductivity to detect when they need to spark, so even slight invisible contamination on the igniter insulator can confuse the sensing system. Also they all seem to fire as a group, so all of them need to be clean because if any one of them is dirty then they will all malfunction.

replace the igniter.

I would try cleaning the burners. You can purchase cleaning brushes made specifically for this purpose and they work like a charm.
