JB850DF1WW General Electric Range - Instructions

had to remove the oven from the wall. once i realized that i had to take the side wall brackets off before removing the oven it was quite easy. then just had to remove oven door and slide the unit onto a chair while replacing the sensor. put it all back in and the wife was so happy to have her oven back she made me a batch of brownies. yum.

un plugged the electric cord. Took back panel off range.
disconnected the element wires. Opened the range door removed the rack, and removed the two screws holding the the bake unit in place and removed the old element. Installed the new element in reverse order above.
After reconnecting the power supply cord turned the range on and let it heat up to remove the newness order off the new element.
tools needed 1/4 inch nut driver or 1/4 inch socket.

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.

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.

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.

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.

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.

Disconnected the old socket ( 2 srews ) removed the two wires from the old socket, reconnected them to the new socket and reinstalled the lamp.

Ordered the dual replacement. I am 76 so I had someone else do it. It took him about 15 minutes. Just pulled the oven forward about 8" so he could lift the top up. 2 Screws to release the top. Then just removed the part and plugged in the replacement. Rescrewed the top screws and pushed the oven back.

First I removed the 4 screws that hold the element in place. I then pulled the element out about 3 inches. I removed the sensor and disconnected the connector.

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.

Very easy to remove the parts and to reassemble

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.
