    The left front burner on our cooktop has never worked. The repairman said that it was defective. That was several years ago when it was brand new. We have gotten along with the 4 other burners,but now I cook more and would love to have the 5th burner to operate.

    Front right smaller burner will not light even though igniter works at trying. The gas orifice I removed, blew pressurized air through it. When held up to the light it shined through it and was visible in the elbow.

    What's next|?

    I don't know the model number but I bought this as a display unit 4 years ago ... just now put it in and all 5 burners worked right off the bat .... 1 day later I have one burner that won't light, igniter works but no gas coming up on the one burner ...I think there may be a spider inside it. Do I just remove the brass nut on top and clean it out?

Take apart the cooktop and it is the potentior on the valve for the simmer burner that is usually the issue.

What the problem is a part in the cooktop that opens to let gas flow to the knobs as soon as they are turned on is bad and no gas coming to surface unit burners. This a safety feature that the German goverment(where Gaggenau is made) requires that part to prevent a gas leak when cooktop is off.

My cooktop has electric ignition that "clicks"

Take a q-tip and clean under where it clicks. Might have food or grease covering release hole.

We have a thermador 5 burner gas range top and the pilot light seems to have gone out. The burners don't go on but we smell gas. How do we re-light it?

Most gas range tops no longer have pilot lights but use an electronic ignition (sparker) to light the burner. Normally when you turn the burner on you should here a snapping or sparking sound, at which point the burner should ignite. Here is a link to the user manual for 36" - 5 burner Thermador rangetop...maybe this will help:

By the way, in the short term you could always use a match to light the burner. JUST BE VERY CAREFUL THE YOU HAVE THE MATCH LIT AND OVER THE DESIRED BURNER BEFORE YOU TURN KNOB TO START THE BURNER!!!!

Constant sparking

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

Thermador gas cooktop explosion

I would say that pop was one of you igniters.  either that or the stove is not installed correctly and when it gets warm, thermal expansion makes the metal pop.  I would say that I would use caution and discontinue its use.  Most problems with these need to fixed professionally.
