Raquel F. provided a link for a previous answer that correctly indicates that the F9 error code means that you have a problem with the door latch assembly in your range. The specific technical information on this failure in your model of Frigidaire range is shown in the image below. If you can clear the F9 by using the 1st two troubleshooting steps shown below then your range may resume normal operations. If the CLEAR key does not eliminate the F9 then you will need to try unplugging the range for 30 seconds. If the F9 returns when you plug the range back in, then you will likely need to have a service technician diagnose and repair this failure. Here is a link for the Sears Service website:

If you want to continue to troubleshoot this problem yourself, then you will need to
unplug the range
and check the wiring between the door latch assembly and the electronic oven control board. Remove the back panels to access these components. NOTE: Internal metal edges and the sides of the back panels can be sharp. Protective gloves are recommended.
The wiring diagram is shown in the image below. If the wiring is okay, I recommend that you check the switches with a volt/ohm meter to make sure that they are working properly. The chart shows the condition of the switches. If you need more help with these checks, reply with additional details and we will assist you further.
NOTE: I do not recommend that you conduct the test that involves applying voltage directly to the lock motor. This type of test should only be conducted by a service technician using proper testing equipment.
These tips may help you determine the cause of your failure in the range.
