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

this video shows how to replace everything on your cooktop, at will help you troubleshoot!

That was a really smart idea to unplug your cooktop and let it dry out. Many times that fixes the problem, however, if the problem returns as in your case it is time to replace the wire harness. Their are 4x switches associated and directly under the 4x burner knobs. Moisture can case a short and send a false single to ignite the burner when nothing has been turned on. Take a look at this picture from the link. Number 12 is the wire harness that has failed.

You can purchase this switch by typing in the model number on a appliance parts website and doing a search.
If you are handy here are some general steps to remove and replace the bad igniter/switch harness.

1. Take off all the grates and burner caps
2. Unplug the unit and turn off the gas line
3. Un-screw the 2x screws on each burner
4. Remove burners and knobs
5. Lift up on the cooktop cover separate it from the burner box
6. Pop off the wire harness switches one by one and observe the way it comes off
7. Place the new wire harness into place and snap in switches then connect wires
8. Reinstall all components

Fasten everything down and retest unit. This job should take around 45min to 1hr to complete.

clean any debris around all the spark electrodes and any ground points near each electrode,food or grease will make them do this,make sure you use a cleaner like isopropyl alcohol or a greaseless cleaner and let dry good before starting unit,if this doesn't resolve the problem,then you need a new spark/ignition module for the unit,but this first step is much cheaper

Try glass plus. Windex has an oil-base and doesn't work as well.

When cleaning, if the control switches get damp, they will react as you describe.
Unplug the appliance, use a hair dryer and attempt to dry the switches.
Leave it unplugged overnight and try them again tomorrow.
They will eventually dry and be OK.

Mis-wired or the new control panel is faulty. Call them back, it is under repair warranty. The parts aren't cheap! https://www.searspartsdirect.com/model/41v4g0ja62-000593/kitchenaid-kecc667bbl01-electric-cooktop-parts ..

igniter failed

Almost certainly the switch, not the element, Had the same problem on a different stove - went to 10 no matter what the knob was set to. Here is a parts list, you should be able to get the part from a local appliance part seller. I used ReliableParts in my town. https://www.partselect.com/ModelSections.aspx?ModelID=815598&ModelNum=KECD805HBL3&mfgModelNum=&ManufactureID=3&Selected=ZPGZLZRB&Position=2&mfg=Whirlpool&Type=Cooktop&Mark=2

They go under the counter and they are screwed in place

How to Install Cooktop

Hi, Need model number of your range to answer this question. Is this gas or electric? Is this a freestanding range or cooktop because I only can find information on ranges with this fault code given. All should EEPROM communication error which is a communication error on start up. when the top was damaged was the unit being used? Was water or liquid a factor when this damage happened? A loose wire would be a different error code or fault code like a F2 - E1 or E2, not your code given. I hope this helps, need more information. Thanks I’m happy to help further over the phone at https://www.6ya.com/expert/gere_bf68e6055dd61249

Call the repair company to come back. It's possible he didn't hook something up right. ...
