JB840TP2CC General Electric Range - Instructions

1) REMOVE ELECTRIC PLUG FROM OUTLET. 2) Pull oven away from wall. 3) Remove the 3 machine screws holding in the top piece of sheet metal. 4) remove top piece of back sheet metal 5) pull knob of the front of the switch. 6) remove the two screws holding the switch to the front of stove. 7) remove wires (needle nose is helpful) one at a time and put them in the same location on the new switch. 8) put new switch into location on the stove and screw in the two front screws. 9) replace sheet metal on the back and screw in the 3 machine screws that hold it in. 10) plug in stove and move it back into position 11) put the knob back on the front and test it to make sure it works ok. 12) be sure to remove power if you need to do open the stove again to correct anything.

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.

This temperature sensor is very easy to replace. There are two screws inside the oven in the top middle of the back of the oven. Take these off. on the back of the stove there is a metal plate with 5 screws I believe. Take these off with a nut driver. Then you will see a white connector coming from the spot where you took the other screws off. Take the white connector apart and pull out the temperature sensor from the inside of the oven. Then put the new one in.

Removed the oven door and shelves. Moved the oven out from wall, so that I could access the rear panel. Unplugged the oven. Removed the five (5) screws holding the rear panel in place and removed the panel. Disconnected the sensor at the connector. Removed the screw holding the sensor in place inside the oven and removed the sensor. Theaded the sensor wire through the rear of the oven wall. Installed the sensor and screw to hold it in place. Snapped the connector from the sensor to the mating connector at the rear of the oven. Installed the rear panel. Installed the five (5) screws to hold the panel. Plugged the oven back in and slide the oven back to the wall. Installed the oven shelves and the oven door.

Unplug the stow.(Important!)
Remove the knobs pulling out from front of the stove.
Remove the 2 screws from each knob.
From rear.(3 big 4 small screws to be removed)
Removing the 7 screws pull up the upper panel get access to switches.
One at a time remove the wiring from old switch attach to new switch. Screw the upper panel. Install the knobs.
Plug the stove.
You are done!
Thanks to PartSelect for their quick response.

The repair was very easy to do. Our oven was showing the F2 error code, which is associated with an over-temperature fault. Upon inspection, the oven was warm, but definitely not beyond the temperature threshold. I researched the issue and found this temperature sensor.
Swapping the sensor was extremely easy. You take off the back panel of the oven, unhook a single wiring harness, and undo some bolts inside the oven, which allows you to pull off the old sensor. Simply hook up the new sensor to the harness, pull everything back through, replace the fasteners, and you're good to go.

I picked the least expensive and most likely issue with our oven that was not indicating a correct oven temperature. I am sure with a 15+ year appliance that the circuitry is on its way out but wanted to give this a try to avoid a new appliance purchase. Oven pre-heat setting takes much longer to finish with the age of the oven. However, after the new sensor the oven will maintain a more even temperature for the cycle.

Removal of the sensor from the inside of the oven is a bit awkward since it is located between the broiler elements at the back but a nut driver was the correct tool and worked fine. A bit stuck with the heating of the connection but pretty simple to replace. Must remove the back first to uncouple the connector. Simplest part of the repair.

At best a temporary fix for a an appliance this old.

Very easy to remove the parts and to reassemble

Unplugged the Range and removed the two screws holding down the cook top. You do not need to remove the vent chamber at the rear of the range since the top lifts up about 4 inches. This should be enough room to get your hand onto the plug going to the door switch. Pull off the plug and remove the swich. Pop in the new one, put on the plug, reinstall the two screws and you are done!

Read the thread on "burnt smell" and DO NOT assume it is a burned out element. Follow your nose!!

Performed repair using a video for reference.

Took a picture of the old heating element to make sure that when I replaced the new element the wires were in the exact location as before.

Took the oven door off and removed the inner door panel, put new glass assembly part in and reassembled. The hard part was getting the door hinges locked back into place.

Watched youtube video. Very easy to replace
