Jenn-Air Gas Cooktop Spark Generator Stays On

We have a ten-year-old Jenn-Air gas cooktop, model CG206B. This weekend its igniter decided to work in continuous spark mode, regardless of whether any burners were on or not. For now we have electrical power disconnected (no spark, no exhaust fan). What do I need to fix/replace, and it this a repair I can do myself?

TIA

: ignitors spark continuously regardless of
: whether any burners were on or not.

That symptom could be caused by moisture in one of the ignition switches that is mounted on the burner valves, a shorted ignitor wire or a defective spark module. The range would have to be examined to determine which was the cause.

Thanks for your reply. I suspect a moisture problem, since the sparking began while the stovetop was being cleaned.

It's quite possible. It may dry out on its own or be helped by using a hair dryer on it/them (after removing the knobs). In some cases the switch(es) may still need to be replaced if drying doesn't solve the problem or if they only work intermittently afterward due to residual moisture or contamination of the switch contacts.
