JES8850BAB19 Jenn-Air Range - Instructions

Parts package contained no instructions. Found all instructions on internet. I used Phillips head to remove two screws on anchor plate of Long Oven Sensor. Located at upper left, back corner of oven; access to screws is not simple/easy. Screws back out w/o difficulty. Pull/extract sensor harness through hole[back of oven] which required pushing aside insulation. The harness barely fits thru hole in oven back metal wall; I recommend using needle nose pliers ( which I ended up doing ) for ease of extraction. Disconnect harness plastic interlok clips. Perfect reconnection of new clip harness with ease. Reverse procedure to complete installation/repair. Done in just over 35 minutes due to wrestling with harness extraction through minimal hole opening. Failure occurred on Thanksgiving Day with 22lbs turkey in oven. Top of turkey contacted sensor tip which eventually caused sensor fault; result was scorched upper breast and oven shut down [safety by design]. Cook top was still operative; clock and all readings on digital control panel ceased. With new 'long oven sensor' installed - good as new. Will be sure to buy turkey(s) under 20lbs in future.

Disconnect the power.took the cooktop off the range. Turned it over. Removed the underside plate. Disconnected the bad element. Pluged inthe new element. Replaced the under plate. Reconnected the range to the stovetop .put cooktop in place. Reattached screws. Turned on power. Worked perfectly.

I watched the video, which was very helpful...the temperature sensor was hard to pull through the small opening in the upper back left oven corner. On the back wall of the oven was a large removable circle, so I unscrewed that piece and was able to gain access to the wires attached to the temperature sensor and push it through the small opening. I used one of the new connectors, pushed it back through the small opening, screwed it back onto the oven wall, replaced the circle opening and tried the oven again...unfortunately, there was no improvement in oven temperature! My JennAir wall oven is about 17 years old, and I thought I would try this $30 repair prior to purchasing a new wall oven, but it looks like I will have to do some overtime and buy a new oven. Any other suggestions would be welcome.

The thermocouple was suspect. It should be super easy- two screws, but the wiring harness would not pull through on my oven. I confirmed the procedure with the PartSelect video which is good. The harness was caught and broke so I had to pull the oven out partially to get to the harness. The sensor did check bad on the multimeter (resistance too high- Google it, I did) so I ordered the part. Once the new part was installed the oven still did not function. So I had to get busy with the multimeter and pull the oven again. On the back of my oven near the wire to the bake element is a Hi Limit Switch which cuts off the bake element if the outside of the oven gets above the preset temperature. Mine was cracked and faulty and had to be replaced. The oven works great now.

I ordered the temperature sensor after watching the video and seeing how easily it could be changed out. Unfortunately, they don't tell you that it may be necessary to access the part from the back. When I tried removing the sensor from inside the oven the connection separated before getting to the hole. I tried for 4 days to try to fish out the other end. Finally, I had my brother help me remove the oven from the wall and take the back off at which time we were able to connect the new sensory. It turns out that the wiring is on the upper right hand corner of the oven and the sensor is on the upper left hand corner and the wiring is rather short. I am a 64 year old female and do the majority of repairs around the house myself, but due to the weight of removing the oven I enlisted the help of my brother. After removing from the wall the rest was a breeze. Just wish the videos or written info on the website was a little more clear as to the different ways of accessing the damaged part.

First I took the door off and outside to dump the glass in the trash which I had some Kevlar gloves so not to get cut. Removed the three screws on the bottom trim piece and the two on the sides remove the outside face glass next remove the four screws that hold the next glass. This glass is in a frame there is bent tab on one corner unbend open frame and install inner glass close frame rebend tab and reinstall all the parts.

Remove sensor from oven. Disconnected wire from back. Connected new sensor and reinstalled. Temps now stay stable.

Removed two screws holding oven sensor in place. Haad to remove part of the back to access wires. Found existing wires had burnt up, and had to reterminate same. Installed new sensor, making sure the leads did not come in contact with the rear of oven compartment. (This may have been what caused failure to begin with)

I replaced the burner

The oven did not auto clean. Problem was the sensor stopped working. Tried to repair from the front but could not get the connector through the hole. Removed the rear panel and found the connector had melted. Could not find a new wireing harnes on line, so I cut the wires on the stove and the new sensor coupling. Spliced the wires togather. The oven cooks fine, I have not tried the cleaning cycle yet.

It's easier with two people.
1 - Turn the breaker for the range to OFF
2 - Verify power is off by testing the burners and lights
3 - Remove front two screws above oven door jamb
4 - Lift the top and prop it up with the spoon, or have your helper hold it.
5 - Loosen the screw at the rear of the bracket that holds the elements against the glass top (front and rear are held by the same retainer)
6 - Remove the bad element by sliding it sideways from the retainer. Do not disconnect things yet.
7 - The burner has numbers around the edge. Move brackets from old element to new one, matching the numbers. Then move wiring to new element. New burner may have a single connector where old one had 2 and a jumper. If so, ignore jumper.
8 - Slide new element under bracket and reinstall the screw.
9 - Lower the range top and re-install the screws.
10 - Turn on power and test.

1. I ordered a replacement heater element from Parts Select, which arrived in just 3 days at my home. 2. I turned off the main circuit breaker to the range. 3. There are two small sheet metal screws inside the top left and right side of the oven door frame which need to be removed first in order to lift and remove the burner top from the range. 4. After lifting and pulling the burner top toward me about 6 inches, I unplugged the left and right burner assembly wiring harness connectors. 5. I lifted the burner top assembly off the stove and turned it upside down an a table. 6. There are six sheet metal screws that need to be removed to allow the sheet metal panel holding the heater assemblies to be lifted off and then also set upside down on a table top. All five burner elements are now visible. 7. Disconnect the slip-on electrical connectors to the specific heater assembly that is defective. 8. Unscrew the three small sheet metal screws from the three spring clips that support the heater assembly on the sheet metal panel; re-attach the spring clips to the new heater assembly. NOTE: Either memorize or record the position numbers that are cast into the ceramic housing of the burner to replace the new burner in exactly the same position. 9. Insert the three spring clips back into the sheet metal panel where the old, defective burner assembly had been removed. 10. Re-connect the slip-on wire clips to the new heater assembly in the same position as they were removed from the defective heater assembly. 11. Turn over the sheet metal panel with the burner assemblies attached and replace the sheet metal screws holding the panel to the stove top. 12. Turn over the stove top assembly and set back onto the range allowing space to reach to the back and re-connect the polarized connectors to the left and right side burners. 13. Slide the stove top back to the rear and carefully lower the front edge back down with the two metal tabs inserted back into the oven door frame. 14. Re-install the two sheet metal screws that hold down the stove top. 15. Turn on the main circuit breaker to the range. 16. Carefully test the new heater assembly by turning the range control knob to LO heat and watch for the stove top burner to momentarily turn red with heat. 17. Turn off the range control knob. 18. You are finished. It was a very easy installation.

The sensor inserts into a slot in the back side of the range. By removing screws on the heat shield on the backside of the range, the sensor wires will be exposed can be unplugged. Then remove the screws that attach the sensor to the back inside panel in the oven. Next, pull the old sensor out. The wire leads will get caught on the insulation blanket, no big deal. Reverse the process to install the new sensor. The new sensor comes with two connector sets for the wiring. I did the whole job for less than the cost of a service call.

Repair video was very helpful. I have removed the screws on both sides of the appliance under the surface plate, in the front. The Owen door has to be open for that. Then I have pulled the surface plate for a little space to disconnect the two connectors. Turned the surface plate over on the kitchen table, removed the 6 screws. Turned the burners assembly over and removed the small burner by disengaging the two clips. I have removed the 2 clops from the burned burner and assembled it to the new burner. I have placed the burner and engaged the 2 clips with a crownose players. I have removed one electrical connecter at a time and connected to the new burner. I have turned over the assembly over the glass plate and assembled the back cover with 6 screws. Put the surface plate on the range and connected the 2 connectors, pushed back, lined it up with the 2 screw holes in front of the range on bot sides and put the 2 screws in and Finished.

Removed the two screws, on both sides of the oven wall corner. Gently lift the front end of the glass top and pull towards me and disconnect the two electrical sockets. Carried the glass top assembly on the kitchen table and turned upside down. Removed the six screws. Removed the assembly from the glass top. Turn the top burners assembly over and disengaged the two clips of the burned out burner from the assembly plate. Transferred the two clips to the new burner on the exact locations like the old ones were. I have placed the new burner on the location and snapped the clips on the slots. Removed the connectors one piece at a time and connected to the new burner. Reversed the previous disassembly and all was done Works like a charm. Thank you all for assisting me in providing the necessary parts and video instructions. It was a lot cheaper than to buy a new range.
