What Does Error F11 Mean?

The LG oven error F11 indicates a potential communication issue between the control panel and the heating system, or a failure in the oven's heating components. This error often leads to erratic temperature readings and the oven failing to reach the necessary temperature within the expected time. If you see the F11 code, the oven may not heat properly, and the control panel buttons can become unresponsive. Regular inspections of wiring and components are recommended to identify the exact cause.

Common Symptoms:

  • Code F11 displayed on the oven panel
  • Oven fails to heat up properly / does not reach ~150°F within expected time (community reports)
  • Buttons on control panel may be unresponsive or erratic (community reports)
  • Oven may stop during self‑clean on some models

Possible Causes

  • Keypad/control panel communication fault (medium)
  • Heating system failure (igniter/temperature rise failure) (medium)
  • Loose or damaged wiring between key components (medium)

How to Fix Error F11

DIY Fix Basic power reset and simple checks

  1. Turn off the oven and disconnect power (unplug or breaker off) for 5–10 minutes to attempt a reset.
  2. Ensure the oven door is fully closed before attempting to preheat.
  3. Check that settings (temperature/time) are correct.

Technician Only Inspect communication and heating components

  1. Inspect and reseat control panel keypad ribbon cable and connectors.
  2. Test temperature sensor resistance for proper value and inspect wiring to control board.
  3. Check bake igniter and heating element continuity; replace if open or failing.
  4. Verify wiring harness connections between control board, keypad, and heating elements.

Parts needed: Control panel/keypad assembly, Control board (main PCB), Temperature sensor/thermistor, Bake/igniter element

🛑 When to Call a Pro:
  • If error persists after power reset and basic checks
  • If wiring inspection shows damage requiring professional repair
  • If heating elements or sensors test faulty and you are not experienced with oven electrical systems
