Product review (5 stars): Works great with  Jenn-Air JGS8860BDP
Had an issue with the oven getting up to temp.  Sometimes it would take an hour or so to reach 350F for example.  Researched online and found that it was most likely the igniter.  Found the part @ sears for 77 bucks.  Looked on amazon and found it for much cheaper and got it here. Easy install on a Jenn-Air JGS8860BDP and now the oven works like new !
