Quick answer
F11 is LG's code for a communication error on a range or oven. Reset steps from the manual and when to call for service.
Model compatibility: LG reuses codes across series and model years, so F11 error may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language

An LG range showing F11 is reporting a communication error. Here is what the manual suggests you do.
Reading the F11 message
Meaning: communication error.
Appliance: LG range with oven.
Series: It sits in LG’s error list for ranges, and no specific model series is named for it.
What owners can try
First, hit CLEAR/OFF. Then repeat whatever cooking function you had selected. A repeat of F11 calls for cutting power at the breaker for half a minute (30 seconds) before turning it back on.
