GE microwaves with a digital display will show an error code when there is a problem or malfunction with the unit. One type of error code that will be displayed on a GE oven and require troubleshooting is a code F3. An F3 error code indicates that the keypad for the control panel is bad or has a short. This will cause the microwave to beep continuously after the set clock message appears.
