Product review (1 stars): We had a bad luck too
Jenn-air gas range has a consistent issue with its control board which will be damaged by the oven heat in about  two to three yeas under light use. Just search "Jenn-air gas range control board problems", you'll find many complaints. One service man even said "see you in 3 to 5 years again" after the new control board installed. We had a bad luck too. The control board was replaced two years ago and now it's broken again. We are not going to spend any money to repair it because we know for sure it will break again. It's a design flaw, and it's designed to die just after the warranty. Never buy any Jenn-air gas range unless you plan to keep the oven idle forever.
