How to Troubleshoot & Replace Ge AP6031743 / WB18X23942 Harness Wire Switch

Replaced harness wiring and transformer. 

I replaced the old parts with these 2 new parts. My stove works again. I like it. 

Turn gas off and unplug the unit Remove burner caps and burner covers. Remove two star screws at each burner that fasten the cooktop “pan” to the burner assembly. Lift pan slightly and disconnect spade connectors at each burner. Set pan aside. The burner switches snap (straight up) off of the gas valves and the harness unplugs. Important to note color of the switch wires and replace exactly as original OEM switch harness. Remove transformer ( unplug input spade connectors and unplug at harness connector. CAUTION Avoid touching the transformer!. Transformer has 3 screws. Simple R&R Replacing these two electrical components was a straightforward plug and play which took me about 30 minutes. Cleaning the upper burners after 15 years of cooking use took a good deal longer that replacing the switch harness and transformer Cooktop works and looks like new after reassembly. Repair cost $202 

While cleaning the cooktop a couple of drops of water fell into the control knob area. It shorted the Wire harness switch, which fried the transformer. I replaced both components as well as the Spark module just as a precaution. The cooktop works perfectly again. 

Chicken stock was spilled on the knob plane causing the LEDs and spark ignition to fail. There are a couple of very good YouTube videos on troubleshooting, definitely check them out. First I bought a transformer and spark module (admittedly elsewhere with better price). I was able to test my transformer and determined it had failed. Changed it out, still not working. Changed out the spark module, still not working but encountered a new aroma indicating the wire harness/switch had probably shorted. Great delivery turnaround from AppliancePartsPros.com! Their video was also helpful even though it was on a range/oven. Replaced the harness in about 20 minutes and back in business. Probably could have returned the spark module but I wrote the installation date with a Sharpie ... oh well.
