JDS8850CDS00 Jenn-Air Range - Instructions

I thought the part might not be available. Ordered the part from PartSelect. Couldn't have been easier.

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.

Door was removed very easily. Outside trim pieces were removed. The rest came apart like a simple puzzle. Inside glass is very easily accessed. Upon assembling, time was well under an hour. Shipping was fantastic and I saved close to 200dollars between a service call and a repair.

Removed the two fastening screws with a small square head screwdriver,lifted the burner head disconnected wire from damaged electrode. To install just reversed the steps,total time less than ten minutes.

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 "Computer" is obsolete, no spares available, some companies will rebuilt for $400+.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

Spoke to your very helpful staff, who advised me that a likely problem was the oven sensor. I took a chance and ordered the part, which came promptly. Your service video for the part was most helpful in my decision to try the part. Installation was a breeze, but it was the oven controller board that had failed and not the oven sensor. That called for a service professional, who ultimately fixed the problem. Your service though, was excellent and I would highly recommend you to others.

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

Installation is simple and very straight forward. Problem, was i stripped the torx screw to release electrode because the screw was frozen. I then tore electrode out leaving space to use penetrating oil (inaffective ) then using a chisel to pop the screw out. It came out intact and did not damage the threads in the burner. So what could have been a 20 minutes job, turned into over an hour. But still worth doing myself.

The porcelain cracked on the burner igniter, it wouldn’t spark and light the flame. I got tired of using the fireplace lighter to light this main burner.

If you have to replace your igniter, it should be very very easy. Remove the two torx screws Holding the cast iron burner to the stainless steel top. Pull it up and the wire connected to the igniter should pull through the small hole in the stainless steel top. Turn the cast-iron base over, pull the wire off, and there is a little screw Fastening the igniter to the bottom of the cast-iron Base. Remove the old igniter and screw the new igniter in place, reattach the wire, and screw the base down to the stainless steel top. That’s it, or how it should be. After years of spaghetti water, gravy, etc. boiling over, I was only able to remove one of the torx screws after using some WD-40 and a torch to heat it up. The other screw sheared off at the head. And a little screw holding the igniter in place, the Phillips head was stripped! I had to leave the roof or the igniter in place, break off all the porcelain, and then break the rest of the metal off leading the screw in place. So I had to use my Dremel grinder to remove some of the metal on the new igniter, then use some tinfoil underneath it to stabilize it in place and then tighten the cast-iron base down using only one screw. Even with one screw and using the tinfoil, it is stable and everything works now. This $27 part was a heck of a lot cheaper than paying $5000 for a new range top!

Hired a pro. Parts are difficult to get on a timely basis today , if at all. Screw up this repair by damaging the outer " black glass " and you buy a new stove. It took three weeks to get my replacement glass even though PS said the part was being sent within a day of the order. Even so , I am am happy to have gotten it , and will continue to use the company.

The video indicating •unscrew old sensor, •pull wiring, •unplug old sensor, and •plug in replacement was good until I pulled the old one and saw wire nuts behind the small square hole! After some research, I learned that the nuts COULD come through that small hole with use of needle nose pliers. One of the wire nuts had the edges pinched off (chipped) in the process. Then I learned about ceramic wire nuts, which I'd never previously encountered. Very important if you don't want to melt your nuts! I cut and stripped the end of a disconnect plug to the stove wiring and now I have a plug in place; which, hopefully, I'll never need to use.

Removed the gas deflector; unscrewed the burner body; pulled off the ignition wire; unscrewed the bad electrode; screwed in the replacement electrode; reversed the steps. Voila! Perfect operation once again. My one mistake? Ordered the wrong electrode initially. Make sure you get the right part the first time around.

Watch the video. Spot on instructions. Easy peasy.

This should be a 5 min job. Lift off the burner cover, remove two screws to lift of the burner base and then remove a Phillips head screw that hold the burner igniter in place.

Unfortunately, the screw holding the burner igniter was rusted and it could not be loosened. WD-40 did not touch it. I used a stronger penetrant, "Blaster". Still it would not budge. Then I used a small Phillips head screwdriver and a hammer which I used as an impact driver. I twisted the screwdriver slightly to loosen and hit it was a hammer. Then I twisted the screwdriver slightly to tighten and again hit it with a hammer. After the penetrant and a couple of more tries, the rusted screw finally moved!!!

With no rust, this should be an easy 5 minute replacement. The burner now works great!!!
