The error code F3 indicates an oven sensor problem. The oven sensor is most likely the failed part. The oven sensor probe must have the correct resistance readings at specific temperatures. When the electronic range control (ERC) cannot identify the correct resistance of the oven sensor or the resistance is way out of specs F3 will display.
I recommend calling a service technician to diagnose and repair your oven.

microwave quits working and F3 comes up on the readout - along with a series of beeps - pressing any of the buttons on the touchpad does nothing - The F3 stays there and beeps intermittently
