JB870DF3BB General Electric Range - Instructions

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.

The real challenge on this particular glass top range was to figure out which screws had to be removed to lift the glass top to get at the burner elements to do a replacement.

Removed the two side screws holding the control panel in place. Disconnected the two wire harnesses and took off the control panel to allow easier access. Then examined the screws attaching the vertical plate in front of the glass top. Most of them were on the on the vertical plate but a few were in the bottom of the horizontal plate. If successful, the vertical plate can be moved forward giving access to the glass top. You pull up on the front of the glass top and when it just clears the vertical front plate you pull the top forward a bit to get the back end of the top out of the read chrome vent piece. I then leaned the glass top up to about a 75 deg angle and then propped the top with a 24” wooden garden stake. I used two stakes to hold the top up. The challenge after that is to remove the old burner and carefully note the colored wiring and locations of the connectors and removed the three old clips. That took a bit of effort. several of the wiring harnesses were very short so you had to be careful when removing and installing the new burner. The burner has numbers stamped on the metal and you must note each number where the clips are located. The rest is to reverse the process. Some of the insulation pieces came off and some of the insulation clips fell off and you must be sure to get the insulation pieces back on in the correct location. Expect a lot of gunk that needs to be cleaned on the top and trim pieces. I save around $200 by doing my own replacement.

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.

pull out stove, unbolt old temp sensor inside stove with 1/4 nutdriver, go to back of stove and take off cover and unhook sensor and hook up new one, put all back together and slide stove back in place.

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.

First and most important trun off curcit breaker. Use 1/4 inch but driver to remove socket (2) screws. Remove ground and hot wire clips from old socket, replace on new socket. Screw back into oven ceiling and turn on power. Reset clock and your are done. Very simple.

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!

I checked various sites on the net and decided that the temperature sensor was the problem. The GE price for the replacement part was about $105, most of the other sites offered the sensor in the $70 range. PartSelect $12.95 When the part arrived, I removed a small self taping screw, pulled the high temperature wire connector into the oven space, disconnected the quick disconnect fitting, attached the new temperature sensor, pushed the connecting wire into its hole, replaced the screw and that was it. I probably saved about $200 in parts and labor over what a local repairman would have charged. Oh yes!! I first disconnected the power at the breaker box. Very important.

Performed repair using a video for reference.

I have a double oven and coincidently I had to replace the two Oven Light Assemblies.
I am really glad about your web site because once I got the number from my oven model you guys were the first ones that came up. Thanks to your prompt and reliable service my oven is back to its original state.

Fue muy facil desconectar primero la estufa despues quite los tornillos de la parte superior detras de la estufa, desconecte un cable del switch y lo conecte en el nuevo despues el siguiente hasta conectar todos los cables en el nuevo switch. Lo mejor es desconectar uno por uno para mo mesclar los cables , despues removi el switch de la estufa y puse el nuevo , puse las partes de regreso y listo conecte la estufa t revise si funcionava el quemador y listo sin ningun problema.

Turned off power at circuit breaker. Disconnected electrical connections from stove and lifted stove top out of counter. Removed glass top by removing about 8 screws from side of stove top.Replaced burner element and replaced glass top.

unplugged the range removed 4 screws from back top cover then took the knob off controller removed 2 screws from behind the knob removed 1 wirer at a time and placed it on the new controller in same order the wires came off put everything back to gather did not fix the problem .

New knob slid right on.

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.
