JB850EF2ES General Electric Range - Instructions

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.

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.

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.

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.

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

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.

My husband and I watched a couple of videos we googled. Once we had a clue we took the top of the stove off. The glass is the whole top, not just glass, and doesn't come with the elements. We marked where each clip was and drew numbers on the elements in order to put them back exactly as they came out. Putting it back together, there are 2 plastic clips, one on each side that we had to get the upper part back on. It wasn't an easy job but we successfully repaired the stove back to new condition.

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.

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.

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.

Well I did it all wrong from the get go. I did finally do a search on how to replace it and then it was quite easy. Learn from me, watch video and save yourself tons of hassle.

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.

Performed repair using a video for reference.

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!
