JCB840SF2SS General Electric Range - Instructions

Literally turned off the water to the refrigerator, disconnected the lines from the back and took one screw loose from the inside of the unit. Slid out old filter connection and slid in the new one and did reverse process.

After replacing the dual element and still having a problem with the range, I started troubleshooting the switch. Fortunately, our range has 2 dual burners, and the switches are the same, so I was able to move the switch and see the problem follow the switch (also, using a VOM, I could tell there was a short in the switch).
Since I'd already replaced the element, I only had to work on the controls, which are very easy to access.
I carefully documented all the connections (took a couple of pictures as well), and swapping out the switch took almost no time.
Lesson learned - follow the manufacturer's requirement to use only cookware with a flat bottom. This tea kettle only sat flat around the outside edge. That caused both the element and switch to blow. The "hot cooktop" light stayed on constantly, even after the element was replaced.

I changed out the sensor and still same problem. Change out Thermosat and still same problem.
I call the help number and emailed the help but I got nothing but have to many calls because of the virus situation.
Still need help.
I’m an electrician and I don’t want to call a service technician and pay that big bill.
Can anyone there help me out, if so please call.

Pulled the oven out and unplugged it. Removed five screws and the back cover. Disconnected the electrical connection. Removed one screw and pulled the sensor out. Installed the sensor and screw. Made the electrical connection on the back, replaced the cover and five screws. Plugged the electrical cord back in and tested the oven temperature compared to the setting. Worked great. My wife then made a small batch of muffins to test it out and they were good.

I just followed the instructions on the link provided with the part

This should have been a very easy fix. But, as I tried to pull out the old temperature sensor, the wire would not come out. I was afraid to pull too hard because I did not want to break the wire. So, I coxed it out easily until I could see the plastic connector. Then, the old wire pulled free from the connector leaving the end of the connector inside the back of the oven. I then had to fish the end of the wire around with the piece of wire through the very small hole in the back of the oven. Once I got it close to the hole, I was able to grab the connector with some needle nose plyers. Connecting the new sensor and reinstalling everything was easy and the oven now works just fine.

Initially replaced the switch on the range--a simple job--pull the wires one by one and place them on the new switch. This did not resolve the problem, which meant that it was the burner, not the switch. I left the new switch in place and ordered a new burner. This, too, was simple, but involved creating a detailed drawing of the switch connectors rather than photos, which, because of the crossing of similarly colored wires, might have been confusing. The only hitch was that the burner is attached to the top by indented clips that fit into pegs at numbered locations on the burner. The clips were very difficult to open and situate, but once done (and this step was the only one where a second person was required) the top was closed and screwed back in place (two screws) and it worked perfectly.

Watched repair videos on YouTube to prepare. The repair was very easy.

Disconnect old burner and reconnect new one

Open the oven , remove one screw holding the sensor remove the sensor and replace the sensor.

Not counting unplugging it and taking off the 3 back panels of the oven (< 5 min.) It took < 2min. to change out. Unclipped cable in back, unscrewed one screw inside of oven at top between the two elements and pulled cable through to front, reversed to attach new sensor. Buttoned up the back, plugged back in and was good to go.

Safety first * Unplugged 220 VAC from outlet. Removed shield cover screws with 1/4" hex nut driver (5 screws). Removed all 6 silver screws from terminal block with 1/4" nut driver, freeing all wires. Removed the green ground screw and ground bracket from center terminal. Cut away (using the drill) melted original terminal block plastic to access the 2 black 1/4" nuts holding original terminal block onto appliance. Discarded the original damaged terminal block. Attached the new terminal block, aligning the mounting holes and the terminal block the same way the original terminal block was lined up and re-used the black 1/4" nuts (original used because the replacement package did not include new black screws). I bought a new appliance cord, since the original cord overheated. Reattached all wires using the 6 new silver screws. Start with the middle terminal by attaching the appliance wires and the ground bracket. The ground must be attached to the bracket and the bracket bridges between the terminal block and the range body. Reattached shield cover. Plugged in appliance. Note: it doesn't matter which outside wire attaches to the outside terminals (both are hot), but the middle wire (neutral) must attach to the middle terminal. However, the ring terminal should be flush on the terminal block so you don't bend the ring.

I am not the handiest person in the world, and this repair was easy even for me. If you suspect that the temperature sensor is the problem, do yourself a favor and buy this inexpensive replacement part and install it yourself prior to calling a professional who will charge a service fee just for checking it out. Pull your oven out from the wall so you can access the back. Unscrew the small nuts on the back to remove the sheet metal cover. Find the wire that goes to the sensor and unplug the plastic coupling. In the oven, unscrew the one nut that secures the sensor to the back wall of the oven. Pull the broken sensor out and replace it with the new sensor. Feed the wire through to the back and plug the new sensor into the same wire that was just disconnected. Reinstall all of the nuts. Do a "test cook" on some frozen food to ensure that the temperature seems correct (i.e., does it cook as expected in the recommended amount of time). The actual repair takes less than five minutes. I put "30-60 minutes" to account for unplugging the oven, pulling it out, removing the screws, replacing the screws, pushing it back in, and testing the temperature.

Being a front burner, I used a 24 in piece of wood to hold up range top. After removing to screws holding top. Made note of numbers on old burner and wire locations. Took off wires and three spring clips. Then replaced with new in numbered locations , wires next

Since this was the third time I did it all I had to take two screws out to lift the top of stove and replace element.
