JB400DP3BB General Electric Range - Instructions

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.

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

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.

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

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.

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.

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.

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.

1.) I removed the old oven door gasket by taking out the ends of the gasket out of the bottom of the oven door first.
2.) Pry up on each one of the retainer clips, they easily pop out of their slots.
3.) Work your way around the oven door gasket.
4.) If any remain stuck you can just wiggle the clip around and it should pop out of each hole. If need be you could use pliers, but I did not need to.
5.) Take your new gasket, it should already have new clips, so you can throw away the old ones.
6.) Work your way around the oven door making sure the clips are nicely seated.
7.) Finish off by inserting the ends back into the 2 holes on each side of the bottom of the oven door, I just used a small spoon to make sure the tops were nicely placed in.
8.) If your gasket needs to compress, you can close the oven door and lock it that should hold it in place and compress it.
9.) All done!

Replaced control panel after removing original control panel facing with heat gun and Wala

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.

I removed the new control panel from its packaging and noticed that the button overlay was not included. I grabbed a putty knife and carefully loosened the adhesive on the old panel and was able to apply it to the new control panel. After installing it I looked up the number of my old panel on the included paperwork and simply entered the “profile” number after powering up the new one and It worked perfectly. I was very relieved to not have to buy a new range!

1) Turn off power at circuit breaker panel
2) Slide out Range from wall
3) Unplug Range
4) Remove back panel and unplug electrical connections to socket
5) From front of oven, remove glass cover over old oven light bulb and remove flange that holds socket and bulb
6) Remove old socket from mounting flange and discard.
7) Place new socket into mounting flange
8) Screw mounting flange and new socket into the oven from front. Reattach electrical connections from back.
9) Screw in new light bulb from front
10) Replace existing glass cover over new light bulb and snap wire holder in place
11) Replace back panel
11) Plug in range
12) Slide range back to original position
13) Turn on power
Works like a charm! Thanks for having the parts after 30 years!

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.

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.
