JB400DP6WW General Electric Range - Instructions

PULL RANGE OUT FROM WALL & ALSO REMOVED OVEN DOOR BY SLIDING UP. WORKING FROM INSIDE OVEN & ALSO BEHIND I REPLACED PART . ALWAYS " UNPLUG " RANGE BEFORE YOU START.

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.

1. Unplug the range power cord from the outlet.
2. Moved range away from the wall and countertop.
3.Using a nut driver removed the 2 screws on each side of the removable panel on the back side of the control knobs and clock.
4. Using a phillips head screwdriver remove 2 screws on top side of the back side panel.
5. Using a nut driver remove 4 screws that secure the main control board in place.
6. Take photo of the wiring on the main control board if not color coded.
7. My control board, and the replacement board were both color coded with the color with the wire placement on the rear of the board.
8. Remove wires with needle nose pliers.
9. Using a hair dryer, heat the plastic control panel face plate that fits onto the front of the old control board.
10.With a putty knife carefully pry the face plate from the old control board.
11. Install the control board face plate onto the new control board.
12. Install the color coded wiring in place on the back side of the control board.
13. Replace the control board into the range, and install screws, and rear panel of the range.
14. Plug cord into outlet and test range for proper operation.

I knew I had a bad control board. Using the repair videos, replacing this part was very easy to do. While I was at it, I replaced my oven temperature sensor. as well, and even though it wasn't bad, I replaced my oven heating element so that I could get some more mileage out of my 14-year-old range. The issue: after completing my repair actions, my oven element still would not heat. I double-checked my connections and I discovered I hadn't ensured one of the wires on the control board was properly seated. This was one of the wires that go to the heating element. After ensuring proper connection, everything worked perfectly!

Easy removal of switch and installation of new switch block.

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.

No parts dealer had a window for this particular oven door. But the associate at Part Select helped me find one that was the right dimensions. The internet videos I found describing installation of a GE oven glass window all described a glass held in place with brackets that don't exist on this model. The broken window was obviously held in place by adhesive. I found a video showing installation a Whirlpool oven window. The construction of the door seemed very similar to mine and the video explained how to attach the window inside the door with high temperature resistant double sided tape. I used Gizhome 3M Double sided Tap. I set door flat on a table unscrewed all the screw (two different size torque screws and 3 screws with nut tops) that held the outer cover to the door. Then I used a putty knife to scrap the old adhesive from the outer door frame. The top of the window is held in place by the metal panel behind the oven door handle. In order to slip the glass under the metal panel I slightly loosened two small screws that held the metal to the door frame. When the door handle is reinstalled it will hold the panel in place. I attached a strip of double sided tape across the entire area that I had scraped adhesive from. I added a short strip of double sided tap on both sides of the window frame, (I'm not certain that was a good idea). I carefully slipped the glass under the metal panel and lowered it to the frame while watching for exact fit. When I tightened the large door handle screws they tightened the metal snugly against the glass. I clamped the glass to the frame at the bottum and placed several bottles of water as weights along the sides of the frame and let the adhesive cure for 24 hours. The project took me several hours because of all the research I had to do. I was thankful for the parts associate's help finding a comparable window.

I turned off the circuit breaker and unplugged the stove. I removed the back panel and marked the location of the wires on the new oven clock control. I detached the wires and removed the old card. I installed the new one and reconnected the wires. I plugged the stove and turned on the circuit breaker. All the lights came on and the oven worked fine. I reinstalled the back panel and it took me less than thirty minutes to complete the job.

I watched a video of a similar model to familiarize myself with the required steps needed. I opened the back and disconnected the power cord and ground wires connected to the removable socket I then removed the lightbulb and removable socket from the oven interior side. I then removed the defective light socket cup and replaced it with the part I purchased. After replacing the removable socket and lightbulb, the bracket holding the light cover functioned perfectly with the new light socket cup. Final steps were to reconnect the power and ground wires to the removable socket. I then replaced the back cover over the light socket cup area. One word of advise. Be very careful when removing and reconnecting the cables to the removable light socket.

One wire at at time then used my razor blade to get front off stuck right back on

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.

replaced handle, which was an exact fit and very easy.

I began by turning off the breaker in the panel.
Slide the oven out into the open area.
Removed 3 screws in order to remove rear top panel.
Took 2 pictures of the wiring location on the PCB
Removed all wiring going to the circuit board total of 8.
Removed 4 screws in order to remove bad PCB.
Remove faceplate from bad PCB (you will need to place this faceplate on the new PCB.

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.

This was simple enough to repair for me, a relative novice. Just remember you need a nut driver to take the back panel off, take a photo of the existing board so you remember which wires go where, and you definitely need a hair dryer to heat up the sticker on the old board so you can remove it and put it on the new board.
