oven wont unlock

Look at page 20 of the service manual I attached. I have also attached a Bosch error code sheet for you oven as well. Take a look at this too. Neither one show an error code of F02. Is that the correct error code you are getting? Any other error codes? Run the diagnostic mode in the service manual to find error codes.

OK. There are a few things that can cause this. First of all, was this in s self clean cycle and that’s how the door was locked? There are thermal fuses that can go bad during self clean causing this to happen. You could also have an issue the the door latch or control board. I have attached the service manual for a similar model. IT should work for the most part for your unit as well. Page 9 talks about the door latch and it being able to be tested in diagnostic mode. Starting on page 21, it lists the error codes and explains how to access diagnostic mode. You will want to check your error codes and run a diagnostic mode to test your components and go from there.
