JDR8895ACB Jenn-Air Range - Instructions

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 "Computer" is obsolete, no spares available, some companies will rebuilt for $400+.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

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.

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.

First I unpluged the range from the power source. Then I removed the back cover, disconnected the two wires to the element, remover two screws on the inside of the oven the held the element in place and removed it. I then installed the new element in the reverse order. This took about one day to get the new part and 15 to 20 mins to do the repairs. I figured that I saved at least $55 on a repairman service call.

Turned off the power to the unit and removed the 2 front screws on the stop-top which are underneath the front when you open the oven door. Removed the back cover and removed the 2 screws for the back of the stovetop and removed the top. Took the old igniter switches out and replaced them with the new set. The connections are simple as they are snap in no wiring required. Replace stovetop screws and replace the back cover.

I removed the two screws, puled out the element and took the pliers to unhook the two wires.

When I was cleaning my stove-top, water got down into the igniter switches, and shorted them out. After buying the switch harness from Part select, I had some idea how to install it, but thankfully they had online, step by step instructions. That save me a lot of time and trial and error time. It went in perfectly with their instructions. Thank you very very much for all your help! God Bless!

remove two screws, remove two slide on wire connections and remove element. reverse to install.

I took the broiler pan out of the shipping container and put it in the oven.

only 2 screws held the element in place pulled the wires and replaced with the identical part very easy to do and thanks for having the part available

First I removed the two screws that hold the element in place. I then pulled the element out about 3 inches and disconnected the two wires.
Installed new element . Connected two wires pushed in place install the two screws.Done....

Super easy!! Your website was very clear about the fact that because my stove has two ovens, it would need two different types of racks. I almost three of the same type at another website until I realized it on yours. Bought two racks, one for the upper oven and only another for the lower one which is bigger and could take two racks, but out of an abundance of caution went for only one for the lower. I have now made pizzas in my (almost) new oven (it feels new because it’s finally usable!!) and made lasagna today for hubby’s birthday. Very happy with my purchase. The only thing was what seemed as an excessive packaging for two flat items. They were put into a flat box and then into a huge, voluminous one with bubble wrap and air filled bags. A little excessive for two metal items, it seemed to me, but otherwise, you have a happy customer. Thank you.

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.

Removed door, dissasembled door cleaned all broken glass, installed new glass, re-assembled door and put door back on oven.

Very simple project.
