How do I fix LG Oven error code F11?

Step 1: Power cycle. Turn off the breaker for 5 minutes. A transient F11 from a one-time slow ignition may clear. Step 2: Test the temperature sensor. At room temperature the sensor should read ~1,080 ohms. Open or out-of-spec = replace. Step 3: Inspect the igniter (gas). Watch ignition — a glow igniter that's dim/orange and slow to light the burner is failing. Step 4: Inspect the element (electric). Check the bake element for breaks or no continuity.

⚠ High Severity 🔧🔧🔧 Advanced DIY

Heat error — oven failed to reach temperature in time

The oven did not reach the target temperature within the allowed preheat window (about 5 minutes to ~150°F), so the control aborts with F11. On gas ranges a weak or failed igniter is the usual culprit; on electric models a failed element or temperature sensor. A failing control board can also report F11.
