JDS8850BDS Jenn-Air Range - Overview

Removed the oven door by opening slightly, then pic door up to remove. Remove 2 screws holding oven sensor in place, gently pull on sensor to remove, had to remove about 8 inches to get at plastic connector. Unplug connector, had to use an adapter cable supplied with the PartSelect kit to install new sensor, push cable back into opening, reinstall 2 screws. The oven works fine! Note that due to thermal lag the temperature overshoots to 370 degrees and undershoots to 340 degrees, this appears to be normal oven operation. Putting door back in place was easy.

As others reported, there are 2 torx screws that need to be removed so that the burner element can be removed. One came out with a little effort, the other one did not as it was corroded. After breaking a torx bit, a second torx bit succeeded in breaking off the screw head. This then required a drill to drill out the broken shaft and then rethreading the screw hole. On to the ignitor replacement. The tiny screw holding the ignitor was corroded and would not come out. It too had to be drllled out and rethreaded. It was a 1/3" #4 screw with fine threads. Had to get it an appliance repair store as the local hardware places don't carry fine threaded screws. Finally got it all put back together after a week. My advice before ordering an ignitor is make sure you can take the current burner off the cooktop first to do the repair in the first place. BTW, the ignitor I ordered came quickly and was the correct part!

First I removed the two screws that hold the element in place. I then pulled the sensor out about 3 inches and disconnected the two wires. Next, I connected new sensor and screwed the new sensor back in place. One area for caution. Make sure that the electrical connection is pushed in past the insulation on the back side of the oven. Failure to do so will cause the plastic plug connector to melt from oven heat.
