The cooktop will need to be removed from the counter. Turn it upside down and remove the screws. The biggest problem will be removing the cooktop from the counter. Sometimes it is not worth fixing as the part could cost around $400. NEVER use a cracked top as it could suddenly explode. This is tempered glass and very unstable if cracked or chipped.

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.

TURN OFF CIRCUIT BREAKER. Lift out cooktop, remove all machine screws holding the glass frame. Remove plastic knobs and lift glass top straight up. Make sure rubber gromits are not ripped or torn. Unscrew the small screws on the selector switch and then lift up and tilt over the small aluminum chasis holding the switches to expose the wiring connections. Pull off the wires and pull out the defective switch. Replacre switch, connect wires, re-seat switch chasis, and secure switch with screws. Carefully drop in the glasstop lining up the switch shafts and the rubber grommets. Secure the top with machine screws and drop back in the cutout.

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.
