JES8850BAS Jenn-Air Range - Instructions

Removed the two screws holding the sensor to the rear oven wall. pulled out sensor wire. It was caught on other wires behind the oven. removed the three screws holding the 8" inspection plate in the center of the rear panel. Carefully move the insulation and reach in to grasp the back end of the sensor wire. Once free from the snag it easily pulls out with the sensor just as stated in the video. using the appropriate adaptor it was easy to re-asseble and and attach to the oven wall. Replace the rear panel with the three screws and it was done

I installed the new oven sensor but the problem continued. So I ordered a new relay board and installed it. Still no luck. So I pulled the new board back out and started trouble shooting it using my electronic background. I discovered the new board was using a pin for L2 that had no exit on the backplane, so I removed it and installed it where I believed it should go. Reinstalled the power relay board and presto. My oven is working lie a champ. Louis

Oven sensor replacement was easy. Thermistor was installed in less than 15 minutes. After installation STILL had "F3" error message. Harness was ok, "Clock" or ECU needed to be replaced. "Computer" is obsolete, no spares available, some companies will rebuilt for $400+. Since the stove was going to the landfill I had nothing to lose by taking the "Clock" apart. It has one chip that is probably the power supply and control chip, another chip is an EEPROM with 128 bytes of storage and the last is a darlington chip that controls the relays. Cleaned up everything that looked like it needed cleaning with alcohol. When I reassembled the unit the pins for the thermistor harness felt loose, so I took it apart, again, and found cold solder joints on all four pins. It must have been there all along but plugging and unplugging the harness finally broke out the solder so I could see it. Soldered the pins back in and now it all works. It's worth a try if you're getting the "F3" message. If the relays on your stove aren't working it would be a good idea to replace the darlington chip. Good luck.

I received my glass panel realy quick from Part Select. It was an eansy job to install the new pane.
It took less than an hour. Thanks for Your prompt service.

installed part,turned unit on-temp still cold. reset digital control, up 35 degrees, still cold. un-plugged unit,re-connect after 10 min. still cold.

First I cut electric power off removed the two screws that hold glass top lifted up and removed two screws that hold element in place. I disonnected the wires and then pulled the element out

1)Pushed the new knob on to the stem of the stove.
2)Walk away
3)Go back to what you were doing
Time required-45 seconds-1 1/2 minutes

Access to burner nothing like on-line videos:

1) Remove 4 screws under front control panel. (Oven door needs to be open.)
2) Remove 2 flat head screws on sides of control panel. This will loosen control panel. Capture control panel to keep from hanging from wires/connectors. I used hooks made from a wire hanger.
3) Remove 2 screws to remove two steel panels on either side of stove.
4) Remove rear screw of the 2 front screws now exposed and 2 rear screws near top of stove.
5) Carefully flip over glass top being careful not to pull on the wires.
6) Identify burner to be replaced. Note 2 numbers where two clamps are attached to burner.
7) Using 3/8” nut driver, remove screws to allow removal of burner. Remove wires per included instructions. Remove burner.
8) Place new burner under clamps and align to the holes by the two numbers noted in step 6 above.
9) Connect wires to new burner as per included instructions.
10) Reverse removal steps.

The control knob PS1174445 fit perfectly flush as intended ...after I removed by hand a small cylinder piece on the shaft. Otherwise, the knob would not fit correctly. Hope this small cylinder removal tip will help other customers as the knob fits and matches perfectly.

I followed the instructions as provided. When I finished I noticed the switch was 1/4 turn out from the off position mark on the stove. So I pulled the stove back out and took the back panel off again pulled the knobs back off took out the screws that held the switches in place and rotated the switch 1/4 turn counter clockwise. Then I replaced all the screws and knobs . Then I replaced the panel and shoved the stove back in place. One of the burners was an eight inch and the switch doesn't work as well as it could. However there was not a direct replacement for the eight inch burner.

Shut off power to the range at the circuit breaker. Remove 2 Phillips screws at either end of the front panel on the L and R side. Open the oven door and remove 4 hex head screws under the panel. Lift up the panel and pull it forward gently. It slips out and hangs on all the wires connecting it to the stove. Unscrew the 4 Phillips screws holding the control panel frame in place. Take pictures of the back of the control board that show clearly the position of the 11 plugs inserted in the board. Gently remove each of the plugs either by pinching open the connector or simply wiggling it out. Insert each plug into the new control panel. This is relatively easy, since the plugs are color coded, differently shaped, and held in the correct position by their wires. Nevertheless after finishing check compliance with the pictures you took. Screw the new panel in place with the 4 Phillips screws. Reinstall the panel, turn on the power, and reset the clock.

Element was sent by buyer, As they recommended, when model of stove given to them. It was upper right rear. When element came. First took off old element. ...Match both element , new element did not look exactly the same, small variation. It did not come on.. I moved old element from left side to right side . Old element worked on both side .. tried new element on left side also.. still didn't work.. so I called right away and explained.. new element did not work.. not defective, but, just wasn't the right one.. I had a specialist came and check it out also. I was told wrong element.

Removed cooktop, wiring and coil. Marked where wires went on limiter
tabs. Ordered coil 1200 Watt, received a 1500 one. Sent back to PS with prepaid shipping label {great}. New one had a different limiter tab arrangement. The instructions included warned this but doesn't tell you where to put the wiring. Instructions say to remove the old limiter and put it on the new coil but this can not be physically be done plus who would want an old limiter on a new coil.
Found a YOU TUBE video on how to test and place wires on limiter switches which shows the number letter sequence on the ceramic part. Maybe PS will put that info in their instructions. Coil works great !!

Removed the original rack. Checked dimensions, installed the new rack.

Replaced the thermostat according to existing videos and had to adjust the thermostat using instuctions in the user manual for model CWE4800ACB.
