ignitor keeps clicking on my jenn-air

hey folks- quick question, the ignitors on my jenn-air JGD8430ADS 4 burner downdraft cooktop just started recently to click by themselfs.It only happens occasionally…Now, i know that all four will click at the same time if the clicking starts ,but when it happens if i quickly touch the front right ignitor with my finger i get a shock…the other three ignitors do not cause a shock. Ihope it is just a bad ignitor($31.00) and not a bad spark module($103.00) . also any ideas on how to replace the ignitor or, if need be, the module…of course ,i will buy my parts here if needed…any help would be greatly apprieciated

Could be that burner lost its ground to the chassis. If there are screws holding down the burner, the screws may have rusted below the burner and interrupted the ground. Remove the screws. if the screws break when you remove them, they are definitely rusted. Unplug unit and drill out the old screws, clean the burners, and new screws should fix the issue.
