How do you replace spark module on GE Cooktop Model JGP963

Remove all the burner heads and lift the top. Sometimes easier said than done. How do you know it is the module? It could be a cracked insulator on the ignitor. To verify you can swap two of the connections on the module and if it lights then it is the module.

You have to determine if it is the electrode or the ignitor module and replace the component. A simple test is to swap the wires on the spark module for the non working one and see if the other electrode still works. If not the electrode is bad, if it does than the module is bad.

If you can hear the clicking sound but are not getting a spark then there is probably a short in the ignition system. Check for any loose wires on the ignition system. Make sure all the wires are properly seated. Make sure the spark module is properly grounded. As far as testing the spark module it should be generating a spark of course. The problem is that the average voltage for the spark module is 15,000 VDC so actual testing of that voltage can be difficult. Is the spark erratic?(should spark evenly). An erratic spark timing is a sign of a bad spark module. Is the spark slow? Check the polarity of the electrical plug. If it is clicking evenly then it is probably arcing somewhere inside the cooktop and you just need to find out where. Also be aware that if you get water into the cooktop that can cause possible grounding of the spark module or ignition system.
