JES8750BAS17 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

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 "Computer" is obsolete, no spares available, some companies will rebuilt for $400+.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.

The sensor is mounted in the top right side of the oven.An extra long screw driver helps to avoid damage to the sensor when replacing it.The connectors were the opposite to the old sensor and I did not see that there were adapter cables included. It might help to connect or tie these together as I only expected the sensor and did not look for adapters.I had cut the wires and used wire nuts when I found the adapters.The repairs works fine.

Watch the video. Spot on instructions. Easy peasy.

Took screws out of the back on the side the sensor was on, unplugged it & took out the two screws on the inside of the oven to release the sensor. Put new sensor in place with the two screws & used one of the adapters to plug in the new sensor. Put screws back in the back panel & turned on the oven which unfortunately is still 50 degrees low. Need a new clock with computer which is out of stock & unavailable. I was an electrician for 25 years so didn't experience any problems. It was a cheap thing to try.

Turned off breakers to oven. Removed two screws that held oven in cabinet. Removed oven door by opening slightly and pulling up on door. Pulled oven out 1/3 of way. Took out four screws on top of control panel. Took oven light switch off by unscrewing holding ring. Removed temp knob on right by pulling. Removed start / stop knob same way.Removed glass straight out. Removed four screws that held elecrtonic clock conrtol board. Unpluged three wire plug from right side and the nine wire plug from the left side. Worked board out at and angle. Went backwards to connect and replace board, screws and door.Slid oven back in and tested oven after turning breakers back on, worked like new.

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.

Went well. Husband, who has some appliance repair experience, did repair in less than a hour. Replacement burner was not an exact duplicate of original but he was able to adjust for that.

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.

Got a bent metal coathook to temporarily release the oven door, removed the screws from the old probe, inserted the new one, and hooked it up, using the one of the plug adapters provided. Problem solved! The oven door latch was now disengaged, the oven would now accept temperature inputs, and the rear cooling fan (which wouldn't shut off) now turned off. That's a lot of things working better for less than $50!

Unplugged the range, removed screws holding the old sensor. When I pulled it out, the wire connecting to the sensor was completely broken through,therefore I could not just pull the wire to get to the connector. Unscrewed one side of back panel to access the connector. Pushed the connector and wire of the new sensor through the hole ( and behind the insulation), disconnected the old sensor and connected the new one. Re screwed the new connector in place plus rescrewed the back panel. Plugged the range in and - Viola! Everything now works like a charm and I have my oven back. Easy-Peasy. Oh - I am an older female with very limited DYI experience. I just saved myself $650.00!

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

I removed the two mounting screws and pulled the harness through the opening unsnapped the sensor from the harness and installed the new sensor i didn't have to used the adapters the new sensor fitted

Replace the racks. No special instructions.
