What Does Error Er OF Mean?

The LG refrigerator error code Er OF indicates that the unit is in Demo Mode, which disables cooling functions and makes the appliance behave like a showroom display. This is not a hardware issue but rather a setting that may have been accidentally activated. Symptoms include the display lighting up without cooling or typical refrigeration sounds. To resolve this, you can exit Demo Mode by pressing and holding the Refrigerator Temp and Ice Plus buttons together for about 5 seconds, or perform a power reset by unplugging the refrigerator for at least 5 minutes.

Common Symptoms:

  • Refrigerator powers on the display and lights but does **not cool**
  • Control panel displays 'OF' or 'OF F' (sometimes shown as '0F')
  • No typical cooling sounds (compressor/fans) if Demo Mode is active

Possible Causes

  • Demo Mode / Display Mode was accidentally activated (high)
  • Power interruption or unintended key sequence triggered Demo Mode (medium)

How to Fix Error Er OF

DIY Fix Exit Demo Mode / Disable Display Mode

  1. Locate the control panel on your LG refrigerator.
  2. Press and **hold the Refrigerator Temp** and **Ice Plus** buttons together for ~5 seconds until a beep and the display changes (varies by model).
  3. Alternatively, press and hold **Freezer + Refrigerator** buttons for ~5 seconds.
  4. Wait for the display to revert to normal temperature readouts and confirm the compressor runs.

DIY Fix Power Reset Before Confirming Demo Mode

  1. Unplug the refrigerator from the power outlet (or switch off breaker).
  2. Wait at least 5 minutes to allow the control board to reset.
  3. Restore power and check if the ‘OF’ error clears and cooling resumes.

Technician Only Confirm Panel and Settings Post‑Reset

  1. Verify the correct model reference for key sequence to exit Demo Mode.
  2. Confirm display panel firmware settings aren’t stuck in demo configuration.
  3. Reinitialize control board settings if necessary according to LG service procedures.
🛑 When to Call a Pro:
  • If exiting Demo Mode and power reset do not restore cooling function but the display still shows abnormal codes
  • If after disabling Demo Mode, the refrigerator still does not cool and exhibits symptoms of real hardware failure (e.g., unusual noises, temperature instability)
