Jenn Air Gas Oven heating issues
« on: August 15, 2014, 10:32:57 AM »
I have a Jenn Air JGS8860BPDP gas oven.  In the last week it started taking a very long time to heat up.  Maybe 45 minutes to get to 400 degrees, but it's also not stopping.  The digital read out on the front will keep moving past the desired temp.  I haven't let it go to see how high it will get, and hitting cancel does turn it off.

The stove top burners work fine, as does the Broil function on the top inside of the oven.

After reading a number of posts I thought maybe the ignitor on the bottom of the oven might be an issue. I removed the bottom panel, set the temp for 300 and watched it heat up.  It turned bright orange and ignited the gas, which was burning with both blue and orange flames. When I checked back in a few minutes, it had hit 258 degrees but there were no longer any flames.  They returned soon after and I then watched as the digital read out on the front of the stove kept climbing past 300.

Any thoughts? Faulty ignitor, thermostat or something else?

No one replied, but I thought I would post that i ordered a new ignitor from Amazon, replaced it and everything is working perfectly.  I hope that helps someone.

I have a similar problem with my jennair jgs8850ads oven . The broiler works fine but the oven burner pulsates . It seems to get to temp OK . Then if you watch the burner you notice the blue flame going up and down the burner it never goes out but you can smell gas . I have replaced the ignitor and the gas valve no luck . Could it be the board , I have already replaced 3 of them .

Check for a spider web inside the burner,run a flexible wire or plastic zip tie up into the burner.I find spider webs all the time in oven and surface burners and your description sounds like that.
