JB645SP3SS General Electric Range - Instructions

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.

Got a new knob.

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.

To Install.
Reverse steps above

Ordered the part, it arrived and 5 minutes later it a complete installation

I started with changing the bulb. I removed the small bracket that holds the glass cover over the bulb unscrewed the bulb and reversed to replace the bulb. To replace the control board I removed the top plate on the back of my stove took the small screw's out of the control panel and unplugged the wire's. Plugged the wire's into the right spots on the new control board and put it back together.

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.

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.

Pulled stove out to access back panel. Unscrew broken switch/stem. Replaced each wire one at a time to make sure they went in right spot. Screw in new switch. Replaced back panel.

Easy

Pull range away from back wall. Remove panel behind control knobs by removing the screws that hold it on. Find hot burner light that holds lens. Remove broken part of lens. Insert new lens into hole on front of control panel and into hot burner light receptacle. Replace back panel. Slide range back into place.

As many people have encountered, my oven would not heat but the igniter would be bright orange and glow! Over time, the igniter wears and degrades causing oxidation to the surface. This cause the igniter to fail and operate at a lower current level, below 2.8 amps! Normal igniters operator over 3.0 to 3.1 amps. When is happens, a low current igniter does not have enough input to the control valve to tell the valve to open to allow gas to flow over the igniter to light the oven, thus heat the oven! This has got to be the NUMBER one reason for an oven not heating!

replaced oven clock control ref maintenance manual, 4 screws and 8 wires. plugged in new control and op checks good.

Unplugged oven, turned off breaker, took cover off back of oven, removed old sensor by disconnecting in back of oven and undoing screw inside oven. Pulled old one out replaced with new took 15min. Cost me less than $20. Parts Select rocks! Even received part in two days with standard shipping!

Once I opened up the back of the range, the sensor wires where there and burnt just like your info said. One nut to take off in the oven and the sensor came right out and the new one went right in. The oven works great, cooked the turkey today. The worst part of the repare was the cleaning behind and under the range, it hasn't moved since it was put in 6 years ago. Very pleased with PS.
