One moment while I get some information for you!

If the unit will not stop clicking one of the switches behind the burners is stuck closed. Each burner has a switch mounted on the shaft. The switch closes when you turn the shaft to the light position with the knob. If a switch goes bad or gets grease in it the switch will not open when you turn the burner off, this will make the unit keep clicking since it is powering the spark module. You can try to take apart the trim to get at the switches and clean them out with an air duster can or some electronic cleaner. You would have to try and narrow down the bad one with a volt ohm meter or by unplugging a wire to each one until it stops. If you can not get the switch to open you will need to replace the burner switch to fix it in the end, some are sold by themselves and others as a kit depending on the model.
