The burner electronic igniter on the right side doesn't turn off, even when the knob is in the off position.I had to unplug the power cord. How do I fix the igniter problem?

Hi,
Here is a tip that I wrote to give details about why your cooktop will not spark to light the burners..

Cooktop Range Stove spark ignition does not work

Electric gas igniters sometimes get stuck in one position causing a clicking sound. The clicking sound that you hear is the electric arc that is pulsing from the igniter conductor (wire) to ground (the gas burner). It receives power from the electrical outlet that the stove is plugged into.
Residue from food and sometimes cleaning products may be preventing the igniter from producing a spark (Arc) to the base of the burner. This is a common problem that occurs when the stove has been cleaned or food is allowed to build up. Make sure that the igniter and the burner base are clean and dry. This will help with proper operation. Oven cleaner and a small tooth brush may be used to accomplish this. Another problem with ignition may occur if you have too little (touching) or too much space between the igniter and the base of the burner; it will prevent the burner from igniting. You should only have a little more space than the thickness of a nickel between the burner base and the igniter. A good “blue” arc from the igniter to the burner base is optimal. If this doesn’t work, you may need to replace the electric igniter module. Good luck.

It works now.After two days of trying, it now works like it should. I'm thinking something needed to dry.

let it all dry out

thumbs up

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 had a similar problem and discovered that the control knob had fried itself, most likely due to liquid penetration down the shaft of the control knob and into the control knob electronics. Inside is a printed circuit board with resistor, diode and a rheostat. The surface of the board was charred beyond repair.
To trouble shoot the problem, open the cook top and hook the burner in question to one of the known good control knobs. If it ignites, then it is the control knob electronics. If it doesn’t, then there is something wrong with the igniter.
Note: The 2-zone Wok Burner had a different control knob that the other burners.
To open the cook top, do NOT loosen any of the Phillips screws on the sides. Here are the instructions from the user manual:
Disassembly
Shut off gas supply, disconnect the manifold pipe, disconnect the electrical power. Remove pan supports, burner heads and burner rings. Remove control knobs.
In the event that the hob is built in, undo the bracket clamps underneath the work surface. Lift the hob on to the work surface. Unscrew the venturis on the high-speed and super high-speed burners using a 20 mm wrench. Lift and remove the burner rings and burner base plates. Disconnect the wires from the ignition plugs. Keep the wire from dropping into the undertray by inserting it in one of the slots in the burner supports.
Remove the three screws securing the dual ring wok burner. Remove the wok burner base plate. Lift the ceramic tray from the hob.
Note: Each regulator shaft is equipped with a black ring. This ring may cling to the rubber seal in the ceramic tray. Check and remove the rings from the rubber seals.

Sounds like the switch electric sending unit needs to be Ither cleaned and dry good or replced. It's not hard at all, They are located under the knob switches, you will have to remove the knobs and the top cover, they look like a small square box wit a hole in the middle with two wires on the sides, just unplug the wires and lift the box off the switch rod. cleane them and dry them good and put them back.......that should do it.....Good Luck

Most likely you got water (or some other liquid) into the control knobs. Unplug, go to bed and try it again in the morning. If you continue to futz with it, you run the chance of burning out the electronics in the control knob, like I did. :(

I've had the same problem for 2 years. Today I removed the four burner tops, the 15/16 inch bolt that holds the burners in place, took everything apart (simple connections underneath), completely cleaned and dried eveything. I also cleaned the 4 knobs and making sure the 4 swiches slide up and down freely then dried everything with a hairdryer. Is now works fine but if the problem comes back, I'll simply unplug the cooktop and light it manually. P.S. I stripped one of the large 5/16 inch bolt that had become weak and brittle. - Try using water or some liquid to loosen the bolts as necessary. Good luck, CHEERS!

Our GE cook-top burner igniter has started ticking even when the oven is shut off. Even after cleaning the bottom of controls the ticking persists. Any suggestions? Thanks
