JES9900CCS02 Jenn-Air Range - Instructions

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.

I switched the oven sensor easily enough, but it did not remedy the problem, so we are in the process of replacing the oven since it's about 20 yrs. old.

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

Watch the video. Spot on instructions. Easy peasy.

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 "Computer" is obsolete, no spares available, some companies will rebuilt for $400+.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 don't want to give Instructions!
Only that we took pictures to use as needed to be sure we knew how to put it all back together!

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.

SHUT OFF POWER AT BREAKER BOX! Remove oven door, use nut driver to remove two screws holding old element to back of oven. Pull forward to get wires into oven, remove wire clips from old part and re-attach to new element using pliers. Re-attach to back of oven, replace door. Turn on power and heat oven to burn off coating on new element. Not at all difficult, except for wire clips are at angle to wire, making re-attachment a bit difficult to do. DO NOT LOSE WIRES INTO BACK AS THEY WOULD BE VERY DIFFICULT TO RESCUE IN A JENN-AIR SLIDE IN UNIT LIKE OURS.
