I have the same problem. I noticed that the oven gets to the selected temp ok. Then when the pilot attempts to RELIGHT, it gets the error F3. Did you get a solution? After other posts, I will see if the temp sensor is around 1100 ohm as suggested by others. Ken

SOURCE: F3 and F2 Error Codes
If hitting clear/cancel won't clear it try unplugging and then plug it back in. My guess is the oven control is bad. Here are the fault codes for this model.
Code Condition Check/Repair F0 or F1 Failed transistor in control If code cannot be cancelled, replace the Electronic Range Control (ERC) or touch pad F2 Oven over temp - exceeded 590F with door in unlocked position or 990F with door locked If actual temp condition occurred, look for welded relay contacts or high resistance connection or any cause in the oven temperature sensor circuit F3 Open oven temperature sensor circuit Measure oven temperature sensor circuit at oven temperature sensor (should be approx 1100 ohms at room temp); check for cut or pinched wire or loss of contact F4 Shorted oven temperature sensor circuit Same as above; check for melted connector or both leads shorted to ground F8 Component failure within Electronic Range Control (ERC) effecting temp processing circuits Replace Electronic Range Control (ERC) F9 Problem with door lock circuit such as pinched wire between Electronic Range Control (ERC) and door lock switch Check wiring and test operation of switch

The f3 error code is a communication error between the control and the temperature sensor. The temp sensor is a small pencil shaped thing in the top of the oven. You will see in when you look inside and at the top back part. You will have to get to the back of the oven to replace the sensor should that need to be done. First thing to do is to turn off the power or unplug the unit. Pull it out and take the back off. Locate the temp probe inside the oven. Then from the back remove the sensor and unplug it. It is an easy fix and most people can do it themselves. If you need a sensor sent to you. I do have them in stock and ready to ship. They are $65.00 including shipping. Thanks and good luck..

Thanks for using FixYa. Error F3 in your range/oven means oven temperature sensor circuit failure. To resolve this issue you’ll have to check the oven temp. sensor circuit if the reading is more then 1100ohms then it should be replaced. Please do rate the solution if the issue is resolved or post a comment for further assistance.
