Error codeF11
ApplianceRange
F11 in brief
What it says: communication error
Appliance: an LG range with an oven
Series: unspecified in the manual
The manual’s reset
Begin by pressing CLEAR/OFF and then try the cooking function again. Should F11 return, shut off the breaker feeding the range for half a minute before restoring power.
If the code is still on the display after that, plan on service, as LG advises.
Model compatibility: LG reuses codes across series and model years, so F11 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

F11 indicates a communication error on an LG range.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
