LG Error Code F0
Shorted CLEAR/OFF key
Common Causes
- 1Keypad issue
- 2Control PCB failure
Step-by-Step Troubleshooting
- 1
Unplug the oven or turn off the circuit breaker for 5 minutes, then restore power — membrane keypad shorts can clear after a full power reset
- 2
If the error returns immediately after power-up, the keypad membrane has a permanent short in the CLEAR/OFF button area
- 3
Check if the keypad membrane is bubbling, peeling, or has visible moisture behind it — heat and steam from cooking degrade the membrane over time
- 4
Disconnect the keypad ribbon cable from the control board and power the unit on — if F0 clears, the keypad needs replacement; if F0 remains, the control board is at fault
- 5
On LG combination microwave/wall oven units, verify you are troubleshooting the correct keypad (upper vs lower)
Pro Diagnostic Tip
On LG ProBake and InstaView ovens, the F0 code is sometimes caused by steam from self-clean cycles migrating behind the control panel and corroding the membrane traces. If F0 appears after running self-clean, allow the control panel area to dry for 24 hours before condemning the keypad.
