How to Troubleshoot & Replace Ge AP2020568 / WB13K18 Cooktop Spark Igniter Electrode

Using the parts diagram and some online videos I learned how to disassemble the cooktop. I called the Appliance Parts Pros rep and she walked me through those things I didn't understand and what parts I needed to order. It then became easy to do once I received the parts. 

Ordered a new electrode and replaced the defective one 

Unplugged the power. Located the hidden tabs (front of my unit), pushed a flathead screwdriver into them, and raised the stove top. Our 1990's GE model has a metal support that engaged below, to keep the top lifted during maintenance. Disengaged the wire connector under the electrode. Using a needle-nose pliers carefully removed the old retaining clip, since I wanted to reuse it. Old electrode was cracked in multiple places and the metal post was corroded. Pulled it out. Put in the new one with the retaining clip, and reconnected the wire. Job took 5 minutes, one of the easiest I've done. Burner now lights better than it has in years, basically comes on instantly. 

Simply switched the part. 

Very easy fix. A 10 min. job. 

Took about 5 min to take the burner apart and replace the electrode. 

I checked electrode by switching with burner that works to verify the problem.I ordered a replacement electrode, took out the faulty one and replaced it with the new one. The video offers detailed step by step directions for removal and installation of the electrodes. In this case, all I needed was a Phillips screwdriver !
