F3 -E0 — GE Microwave F3 — Shorted Touch Panel
F3 indicates a shorted touch/keypad panel — the control detected a shorted key for more than ~60 seconds. (There is no separate F3-E0 subcode; F3 itself is the shorted-touchpad fault — do not confuse it with the thermal/humidity sensor codes F1/F2/F4/F5.) Check the touchpad and its ribbon connection.

How to fix it
- Unplug the microwave for 5 minutes.
- Restore power — if F3-E0 returns immediately, the short is permanent.
- Unplug again and disconnect the keypad ribbon from the control board.
- Power up briefly — if the code changes to a 'no keypad' fault, the keypad is the problem.
- Replace the membrane touch panel with the OEM part.
- If the code stays F3-E0 with the keypad disconnected, replace the control board.
