Gas cooktop igniter sparking

I have a Thermador gas cooktop. Just now, while using one of the burners, another (unused) burner's igniter started sparking. Of course, the gas wasn't on, so there was no ignition, but it shouldn't have been sparking.

Anyone ever run into something like this? Is it fixable?

It is fixable in most cases sometimes more costly depending on which part has failed if any.

Did you have a boil over before this started to happen?

If not possible cause could be spark sw. spark module, and ignitor gap , water or liquid in switch or ignitor.

Hello ericbro and Welcome to my Gas Appliances topic.

Possibility of moisture during the cleaning process found it's way onto one or more of the switches. Excessively wet sponges or cleaning cloths allow water to get onto the switches, which will cause this problem, if applicable.

If this happens to be the case, then remove everything on the stove top and lift the lid, if applicable, since not all stoves have liftable top lids.

Remove any clear plastic covers on the valve stems, if applicable. Blow warm air over the switches using a common hair blow dryer. The idea here is to dry out the moisture, if there is any. Don't laugh....this hair dryer trick often works!...

The sparking modual may be defective. In this case, you can remove it and have it tested. If it tests bad, replace it. If you attempt to do any repairs, be sure the electrical power is turned off or the stove is unplugged.

If all the sparkers are sparking, the most likely cause is a defective capacitor in the spark modual. Spark moduals are not repairable. The entire part must be replaced.

Retail parts dealers can also help determine what the possible problem may be. Bring the make, model and serial numbers. Appliance parts dealers carry replacement parts for all appliances and are listed in the phone book under appliances.

Read the manufacturers online web site for product information, problem possibilities, causes, solving methods, part locations, disassembly, reassembly methods, repair procedures, pictorials, schematics, downloadable repair and or owners manuals which may be available online.
