Igniters do not spark on one side of cooktop

Igniter does not spark on one set of two stovetop burners.

Four burner gas cooktop, two each side. I have swapped the two burners on the right, with the two on the left and problem moved with the burners. Disassembling the two non-igniting burners revealed no obvious problems. The wires are intact, I cleaned the contacts. Ideas?

Actual Model number is JDS9860AAW

    Sorry forget to say, gas flows freely, just no spark. I can light the defective two burners using a match.

  • jdmccoy Jul 11, 2008



    The ignitors are on each burner. Appears to be a simple setup, a wire runs to each burner and the spark ignites the gas when the control is turned to ignite. All four burners originally sparked when any burner was turned to ignite. Now only two burners have spark. The wires appear in good shape, the ceramic housing around the spark point appears okay. There is no resistance between the contact point of the ignitor wires and the spark point, measured using my home meter.

  • jdmccoy Jul 11, 2008

    I do not understand how the ignitor functions or how to measure the voltage. The ignitor protrudes under the burner. When the knob is turned to start the gas flowing and ignite the flame, the ignitor sparks. It does not appear the the surrounding burner is grounded as I cannot get a zero resisance reading through the paint or whatever material is covering the metal. How should I measure the voltage?

  • jdmccoy Jul 11, 2008

    There is voltage on the non-functioning side, however, not as much as on the side that ignites. I do not know how much as my home meter jumps around. After shutting off the gas, and trying to get the spark, there is sometimes a small spark. If I remove the functioning two burners, the remaining two still do not spark.

    It is the wires! Thanks for the help.

Is the gas able to flow freely through and out of the bad burners? Sounds like they may be clogged somehow

    Is the igniter mounted to the burners individually?

  • Mike Wright Jul 11, 2008

    It looks like you've been pretty thorough with this. When you attempt to spark, does the multi meter you have, detect any voltage coming through to the other end? (if possible without the gas on) lol

  • Mike Wright Jul 11, 2008

    All you would basically be looking for, is to see if the meter showed any signs of voltage hitting when the igniter should be sparking. As far as a ground... Is there an overhead vent/light setup installed? It should provide a good ground for you.

  • Mike Wright Jul 12, 2008

    I wonder if the integrity of the wires providing the spark is degraded... I'm sure what else to say. Are you able to swap the wires from the functioning burners? (just to see if it is indeed the wires)

  • Mike Wright Jul 12, 2008

    As far as getting replacement wires... You could try contacting the customer service for the maker of the grill. Or maybe bring the bad wires to a Home Depot or Lowe's. They should have them. Thanks!

Cooktop burner do not ihnite


Hi hgodoy2 - Is the electronic igniter aligned properly? Ensure that tip of spark igniter is aligned with metal point or "nib" located on underside of burner cap after the burner mounting screws have been tightened. (Not all burners having mounting screws). When the burner control knob is set to the "LITE" position do the igniters spark? Can gas be heard or smelled coming from the burners when the control number is turned on? However, if you smell gas, I highly recommend turning the unit and the gas off if you can reach it and contact your gas provider. The range itself does not have a switch or regulator to relight it. Keep in mind that it may be experiencing an issue with the spark module, electrodes, wiring or EOC.

Electronic igniters will not turn off when the gas burner lites. all four igniters run untill you turn off the nob or unplug the unit


I'm dealing with this same problem. This cooktop has a dedicated simmer burner which is the only thing going on the lowest setting. This simmer burner seems to be how the igniter senses that it can stop. If it doesn't light, the igniter keeps clicking. Usually cleaning the burner will solve this. You may need to unscrew the nut holding the lower piece of the burner in place in order to clean it up.
Good luck!

When you turn the burner on, it makes a popping noise and will not stop.


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

The igniter on the right front burner of my GE Gas cooktop does not work....I must use a lighter or match to ignite....What can I do? There is no clicking sound when I turn on the burner?


all burner igniters work at the same time - you may have a faulty electronic spark unit. change the spark unit. go to repair clinic dot come for the unit. also would be wise to check the ingniter start switch on the gas burner control knob

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
