How to Troubleshoot & Replace Ge AP2023913 / WB23X5340 Oven Temperature Sensor

Bought the heating sensor from Appliance Parts Pros and installed it in my oven in about 15 minutes. Oven works great. 

Setting heavy cardboard (from an old big box) to protect the kitchen floor, I pulled the unit from its position to access the rear panel (circuit breaker off and unit unplugged). I unmounted the sensor with a nutdriver and a flashlight (it is dark in there). Turning to the rear, I easily removed the large rear panel (6 screws, same nutdriver) which immediately revealed the sensor wires and wire harness. It was then that I discovered, to my joy, that the new sensor's plug was identical to the old. No wire stripping and nut splicing needed; this was a direct replacement!! Popping the plug tab with a small screw driver I disconnected the wire plug and gently pulled the sensor out of the unit from the front (oven side). Then I threaded the new plug and wires gently through the hole and insulation using a slender screwdriver, and remounted the sensor in the oven using the original screws (old sensor) and nutdriver. Back to the rear, I simply connected the plugs, arranged the wires as they were before, and remounted the rear panel. Plugged the range in and turned the breaker on. Perfection, just like new. Then I slid the range back into place. In all, this took maybe 15 minutes, not counting the opportunity to clean the range sides and floor and wall. This was smooth and easy!! 

Replace the temperature sensor 

Replaced it with new sensor 

I ordered both the bake element and temperature sensor, which arrived quickly. I had changed a bake element before so attempted this one. However, on inspection, the connecting wire from the oven looked damaged at the terminal end. I found 2 new terminals at a local appliance parts store. (They were free.) Also, the temp sensor had to be straight-wired with the wire nuts included. Although not a difficult job, I didn't have the confidence to tackle re-attaching the terminal ends or straight-wiring the sensor myself. My handyman had everything fixed and working in less than 1 hour. 

Replaced thermostat probe. 

Started by replacing the bake element in the oven but it still would not heat up properly. Then replaced the thermostat and it worked fine. Both of these jobs took maybe 20 minutes combined, but then of course I felt the need to clean the oven while I was in there and that took the rest of the day. LOL I had trouble with the bake element connectors staying on so I took the back off and reconnected them from there, crimping them down tighter with pliers. 

In about 45 minutes with very few tools 

Used internet to find problem. 

I ordered a part from AppliancePartsPros.com and had to pull out the wall oven and disconnect the sensor from the back and hard wire the new one in.
