read your user manual
could be a simple thermostat turning it down/off when the set temp is reached

Take the switch buttons off and use a hairdryer to blow dirt out and dry up any damp. Also make sure buttons go up and down cleanly.

Looks like you may have a bad ignitor. Try adjusting the arc gap. Sometimes of the ignitor is too close to the burner, the ignitor will not spark. It may also be that te burner is dirty and needs a little cleaning to allow for the electric ignitor spark to arc accross, thus producing ignition. Good luck.

Hi,
Here is a tip that I wrote that will help figure out why the burner spark keeps on clicking...

Will most probably be a problem with your ignition box. If you want to test this try taking off the hob by undoing the screws under the burners, be very careful with these however as it is very easy to strip the thread on them, once you have the hob off try unplugging the ignitor that keeps sparking and swapping where its plugged into the ignition box with another ignitor. These ignitor can be plugged into any plug in the box so no worries there. If the ignitor keeps sparkings in another hole its the ignitor. If the new ignitor sparks its the ignition box. It will most probably be the ignition box. Is a common fault

I had a similar problem and discovered that the control knob had fried itself, most likely due to liquid penetration down the shaft of the control knob and into the control knob electronics. Inside is a printed circuit board with resistor, diode and a rheostat. The surface of the board was charred beyond repair.
To trouble shoot the problem, open the cook top and hook the burner in question to one of the known good control knobs. If it ignites, then it is the control knob electronics. If it doesn’t, then there is something wrong with the igniter.
Note: The 2-zone Wok Burner had a different control knob that the other burners.
To open the cook top, do NOT loosen any of the Phillips screws on the sides. Here are the instructions from the user manual:
Disassembly
Shut off gas supply, disconnect the manifold pipe, disconnect the electrical power. Remove pan supports, burner heads and burner rings. Remove control knobs.
In the event that the hob is built in, undo the bracket clamps underneath the work surface. Lift the hob on to the work surface. Unscrew the venturis on the high-speed and super high-speed burners using a 20 mm wrench. Lift and remove the burner rings and burner base plates. Disconnect the wires from the ignition plugs. Keep the wire from dropping into the undertray by inserting it in one of the slots in the burner supports.
Remove the three screws securing the dual ring wok burner. Remove the wok burner base plate. Lift the ceramic tray from the hob.
Note: Each regulator shaft is equipped with a black ring. This ring may cling to the rubber seal in the ceramic tray. Check and remove the rings from the rubber seals.

gud day,try to clean the bottom of knob control by removing of knob then clean if by using a vacciumm,if u want to use manually ur cooktop unplug the unit to stop the cliking,then use macthes every time to on the gas cooktop.

the ignitors have got wet usually due to cleaning. they are usually located under the rotating switches just let them dry out ( very well .....may take days) and it will work normally again

Hi
Glad to Help you!!
Take the knob off, them remove the cover that housed the switches, OK, Now, Look at the switch that is continiusly clicking and it will have two wires goin onto it, remove these wires and just lift the sending unit, and inspect it for water, grease etc ect....clean and dry and put back on and try again it should work, if it does not work, then just get a replacement one, they are not expensive, I just replaced two on my Jenn-Air myself and it cost me $25.00.
Hope this will help!!
