Replaced spark module and ignitor harness as I was not sure which specifically was the issue as symptoms pointed to either or both and I didn't have time to play the trial and error game of guess which part is failing. I had to remove both back panels. Remove all knobs, knob faceplate, disconnect all burners from the top, then completely remove the top. Remove the spark module (Black Replacement is larger than Factory but snaps in just like factory). Replacement also has a ground which factory does not so I had to get a little inventive with securing grounding location. Replaced one igniter rod cable at a time from old to the new spark module to make sure to not lose location assignment. Snap off ignitor harness points, align the holes with pins and replace. Red goes to the spark module, black went to the back of the stove thus the removal of back panels. Re-assemble in reverse order of disassembly and you should be back in business.
