Spark Ignition Switch
One of the spark ignition switches might be defective. The spark ignition switch sends voltage to the spark module. When the electrical contacts inside the switch close, power flows to the spark module. If the spark ignition switch fails with the electrical contacts closed, the switch will send continuous voltage to the spark module. To determine if any of the spark ignition switches is defective, use a multimeter to test each of the switches for continuity. If a spark ignition switches shows continuity at all settings, replace it.
Spark Ignition Switch and Harness
One of the spark ignition switches might be defective. The spark ignition switch sends voltage to the spark module. When the electrical contacts inside the switch close, power flows to the spark module. If the switch contacts are wet or stuck in a closed position, the switch will send continuous voltage to the spark module, no matter where the dial is set. Each of the switches can be tested individually to determine if they are shorted. If a spark ignition switch is shorted and is not wet, or if drying it out doesn’t solve the problem, replace the switch.
The spark module provides power to each surface burner spark electrode. If the spark module fails, it may cause the burners to spark continuously. However, the spark ignition switch is more likely to be at fault. Before replacing the spark module, first test the spark ignition switch. If the spark ignition switch is working properly, consider replacing the spark module.

If cleaning and drying the burner, burner cap to burner mating surfaces and igniter does not rectify your constant clicking...
The semiconductors used in all ignition modules are almost always manufactured from consumer grade components. I have never in my career seen one with automotive grade temperature semiconductors.
It gets very hot in cooktops and slide in range cooktops, easily exceeding the highest temperature ratings for the semiconductors. The net effect after time is that the current sense portion of the circuit pinches off the feedback current from flame rectification signaling no flame is present and fires the ignition repeatedly.
Retrofitting the location of your igniter module to under your counter cooktop airbox will keep the IC’s in temp range and extend your spark module life to at leas the design life of 10years and most likely much longer.
why my stove damage the metal knob when i pressed pulsed igniter ? ?

We have the same issue with one front burner clicking while on, but if we turn the burner on behind it then the clicking stops. Any ideas what this is?
