My oven started shutting off and giving me a error code E4 -F3-. I purchased a new oven sensor part # W10181986. I installed the new sensor. The oven will work for about ten minutes or so and then it will beep and give the same error message. I tried unplugging the stove for five minutes with the same results.

I am assuming that it only happens when you use the lower oven.
Most likely it is the control board.
I would check any connectors between the sensor and the control board.
Could be a bad/cold solder joint on the control board.
Cold solder joints are often a duller silver color and/or may have pin holes.
Gently wiggle the sensor connector on the board while looking at the solder side to see if the connector leg moves in the solder.
Check the solder for other components in the sensor copper trcks onn the board.
A magnifying glass help with the above checks.
If all looks OK then odds are that the control board is toast.
