Ignitor Clicking Continuously

Hi, We were relaxing, watching TV (couple of hours after dinner) and suddenly we started hearing this annoying continuous clicking from our gas cooktop. We have Jenn-Air sealed gas cooktop (Mod: JGC8536) about 4.5 years old. The clicking stops when I unplug te cooktop from the electric outlet underneath the counter. But as soon as I plug it back in, all 5 burners start clicking. Only when the top left burner is ignited the clicking stops on all burners; lighting up any of the other 4 burners still produces the clicking. I read some of the posts for oter models and sounds like it could be moisture or spark module or ignitor wiring?? I’d appreciate any thoughts you can share about this Jenn-Air model and this problem. Thanks!
