Our kenmore 790 built in oven keeps flashing an F30 code after we turn off the oven, or sometimes when the oven is on, it shuts off and then beeps the F30. I keep hearing it is the RTD probe, but where is it and how do you replace it?

The F30 error code indicates that the electronic oven control board detects an "open" oven temperature sensor probe circuit.
This is usually caused by a failed oven temperature sensor probe.

Replacing this component will likely fix your problem.

You can order this part from www.searspartsdirect.com website.

If you replace this part yourself, be sure that you unplug the range to disconnect electrical power before accessing this component.

On some models, you can replace the probe by removing the screws that mount this component to the inside back wall of the oven.
Carefully pull the probe inside the oven cavity until you encounter the wire harness disconnect plug.
Unplug the sensor and replace it with the new one. Mount the new probe on the back wall of the oven.

On some models, you have to remove the lower back oven panel to access the sensor probe.

If you replace the probe and still have this problem, you will need to unplug the range and measure the resistance through the violet wires that plug into the control board (this is where the sensor probe circuit is connected to the control board).
If the resistance through the oven temperature sensor probe circuit is normal (about 1100 ohms at room temperature) then the electronic oven control board will need to be replaced.
