Customer Question

GE ZGU385 gas stovetop I spilled water on the stovetop and a fair amount (1/4 cup?) went down under the control knobs. Right away the sparker started acting funny and eventually the electrical components stopped working (no sparking and no indicator lights).
I jumped the gun and replaced the spark ignitor. That didn't help, I don't think that's the problem because that has nothing to do with the indicator lights. So, now I have two questions: 1) Does it sound like replacing the Spark Ignition Switch and Harness
would solve my problem? Could that be where the problem happened? I'm guessing it might because this is where the water generally went. This part: http://www.repairclinic.com/PartDetail/Spark-Ignition-Switch-And-Harness/WB18T10410/1473712?ss=c35-x7a6775333835&mr=1?RCAID=1000057
2) If this might help ... how do I get the old harness detached near the knob hubs? They appear to be pretty well affixed. Thanks Bob

OK, I replaced the transformer today, and didn't have a very good result. Once everything was hooked up and I plugged the unit back in ... I could hear "crackling" in the left-most knob connection. I believe I could smell it as well. The transformer got very hot very fast. The light which is meant to come on when the knob is turned did light up for a bit, but quickly went dead again.My guess is that there is now a short in the wiring assembly that runs through the knobs (but that is totally a guess). I also worry that I've burned out a brand new transformer.So, my options are to purchase a new wiring harness and try again or call someone for service.Is there a way to test whether the new transformer has burned out? Perhaps the old one was never burned out?

You can see if you have power out of it with a volt meter, but yes it sounds like the harness is bad for sure.
