LG Refrigerator rF / E rF / Er rF Error Code

The rF family indicates that the refrigerator compartment fan is not operating normally. The safe first steps are documentation, food-safety awareness, door and loading checks, and one supported power reset.

Applies to LG refrigerator with digital or led error display

What the appliance detected

Detected condition

LG identifies rF as a refrigerator-compartment fan motor abnormality.

What may contribute

Possible causes

  • The refrigerator compartment fan motor is not operating normally.
  • A temporary control or power condition may clear after the LG-supported reset.
  • An internal fan, wiring, or control issue may require LG service if the code repeats.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the display and model

    • Photograph or write down the exact display, preserving the lowercase r if shown.
    • Confirm the full model number and owner manual before using any model-specific controls.

  2. Check cooling and food safety

    • If the fresh-food compartment is warming, avoid repeated door opening and use food-safety judgment for perishable food.
    • Stop for a burning odor, sparking, visible electrical damage, repeated breaker trips, or water near electrical parts.

  3. Check accessible airflow conditions

    • Make sure doors close completely and food is not blocking visible interior vents.
    • Do not remove covers, shelves that require tools, fan shrouds, or internal panels.

  4. Power reset once as LG documents

    • Unplug the refrigerator or turn off the dedicated breaker, wait about five minutes, and restore power.
    • If the same code repeats, preserve the code and request LG service rather than continuing to reset it.

Actions not recommended

  • Do not remove panels, access the fan, test wiring, bypass switches, or replace parts based on rF alone.
  • Do not keep resetting a returning code or ignore a warming refrigerator.
  • Do not use improvised heat, sharp tools, or disassembly to reach hidden frost or fan areas.

When to stop and request service

  • Request LG service if rF returns after one documented reset and accessible airflow checks.
  • Request service immediately if the refrigerator is not maintaining safe temperatures or any internal inspection would be needed.
  • Stop for electrical warning signs, water near electrical components, visible damage, or repeated breaker trips.
