JB850DF1BB General Electric Range - Instructions

Pulled stove out and unplugged. At the rear of the range there were 4 faster. Used a nutdriver piece in an electric drill. Pulled off the cover and located the switch. At the front of the stove, I removed the knob and unscrewed two screws releasing the switch. I undid and replaced each wire connector one-by-one to avoid any wrong connections. Replaced and secured the switch and replace the back panel. All secured, power on and fixed! Easy repair, but something that had been put off for a year!
Also follow the installation videos from PartSelect - very helpful!

1) Shut off power to oven
2) Removed oven door using snap down hinges on door
3) Removed 4-phillips head screws holding the oven frame to cabinets
4) Pulled oven out of cabinet and set it on stool in front of opening
5) Remove 2-hex screws holding metal shield covering the electrical wiring on back of oven
6) Unplugged bad thermostat connector
7) Removed the single hex screw holding thermostat inside the oven
8) Pulled the thermostat and lead wire from oven
9) Fed the new thermostat wire into inside back of oven
10) Reverse steps 1-7

Removed torx screws for door handle as well as torx screws for both hinges to separate the door halves to extract broken glass and to install new glass panel. Other reviews said not to remove hinge screws, however I had no problem reinstalling them.

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.

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

0. As a safety precaution, unplug the range or hit the relevant fuse breaker before you start. You might also want to grab a flashlight. Definitely do not try to do this while the oven is hot.
1. Pinch the wire over the light bulb cap to remove it. This is inside the oven at the back.
2. Pop off the hemispherical glass cap.
3. Unscrew the old light bulb, and screw the new light bulb in its place.
4. Put the cap back.
5. Secure the cap by putting the wire back in its slots on the cap.

No tools needed, the cap is just held in place with pressure from the wire.

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.

First I cut the circuit at the breaker, and then pulled the range from wall to access the access panel. This top panel was held with 4 screws and removable with a standard phillips head screwdriver.

I then removed the 5 wire-crimped fasteners from the defective surface burner switch. (I first labeled these wires to ensure correct placement to the new switch). There were an additional two screws behind the corresponding knob that needed to be removed in order to completely remove the old switch.

The new switch was installed in reverse order to the steps indicated above (two screws behind knob, 5 wire-crimped fasteners, 4 screws to panel). Range was pushed back into position and breaker turned on.

RE: 2 yr. old GE double wall oven with convection option in upper oven, non-convection in lower oven: baked goods were not browning, were undercooked or burned. Tested both ovens on regular bake setting using 2 oven thermometers. Set ovens for 350. Although after 10 min both ovens beeped "ready", the oven thermometers actually read 200 - then would swing up as high as 500 and as low as 200 during the 20 min test period. Decided to first replace top oven sensor only, just in case it really was a more expensive control panel problem. It was a bit awkward to reach back there with the oven door in the way, but I have long arms! Aimed my flashlight, removed nuts with a socket wrench, pulled out the sensor, popped the clip and the old sensor easily separated from its connection. Snapped on the new sensor, pushed it back in and reset the nuts. Easy. Set the oven for 350 and tested again with 2 oven thermometers for 45 min. Voila! The oven thermometers read exactly 350 when the oven beeped "ready" and it stayed at 350 throughout the entire 45 min retest period with only a 3 degree variation both up and down. What a great improvement! Immediately went online to Parts Select and ordered another sensor for the bottom oven which was having the same problem. Fixed both ovens all for under $30 - and just in time for Christmas cookies! Don't want to know what the repair guy would have charged.......Merry Christmas!

Replaced burned element, did not fix no power problem. Ordered receptor replacement, replaced it, took less than 10 mminutes, but still no power to burned. Then ordered replacement switch, replacement too less than 10 minutes again and burner works fine.

Removed screws holding temp sensor, pulled wire out from behind wall until found connector, disconnected old sensor.
Measured resistance of old sensor and compared with new sensor, they measured nearly the same. Installed the new sensor and tested the stove. Came up to temp ok. No problem since, about 2 weeks.

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.
