How to Troubleshoot & Replace Ge AP5790793 / WB21X10165 Oven Temperature Sensor Assembly

Replaced both temperature sensor and cooling fan. New parts fixed the problem. The oven wouldn’t turn on. 

GE double oven, replaced the sensor assembly on the lower oven. 

I didn't fix it. I changed the oven temperature sensor ($43) but that did not fix the problem. So I bought a Kitchenaid KOED730 and that fixed it. I was happy with the part and the delivery as I received the part the day after I ordered it. It took me an hour to fix it but I am 90-years old and, 20 years ago, I could have done it much quicker. 

Utilized this video to fix the oven. https://m.youtube.com/watch?v=LfeWKMPldY8&pp=ygUURjM0IEdFIFByb2ZpbGUgZXJyb3I%3D 

I replaced the board machine control for the upper oven 

Ordered $35 temp probe, watched helpful video on your YouTube channel. Easy replacement. So far seems to be working. 

Temp was running 30f low. The tricky part was trying to get the connector to come through the wall. I used a screwdriver to slightly move the insulation out of the way and pulled on it lightly and it came through so it was a pretty easy fix. But since I did not turn off the power first, I got an error code when I disconnected the sensor. So I just cycled power and it cleared, then another code came up but it cleared itself within about 5 seconds. You do need a torque screwdriver. Not sure what size but it was the littler one. 

Replaced main control board using part from appliance parts pros 

Removed oven from wall disconnect the power. Removed top and back sheet metal so I can see wiring. Tested sensor for resistance. Ordered two new sensors and a CU board. Only installed sensors since oven turned on and will test unit for one week before installing. 

Purchased a new temperature sensor and replaced it. The process was very easy. Just one screw. The whole thing was done in about 5 minutes.
