What Does Error Er rF Mean?

The LG refrigerator error code Er rF indicates a refrigerant flow issue, often linked to a malfunctioning evaporator or fan motor. Symptoms include a warm interior, reduced airflow, and unusual noises from the fan. Common causes include fan motor failure, ice buildup obstructing the fan, or wiring issues. Addressing this error typically involves checking for frost buildup and inspecting the fan motor and wiring for faults.

Common Symptoms:

  • Error code displayed on control panel
  • Reduced or no airflow inside refrigerator
  • Warm refrigerator compartment
  • Fan not spinning or making unusual noise

Possible Causes

  • Evaporator/fan motor malfunction (high)
  • Ice/frost buildup locking fan (medium)
  • Obstruction or debris preventing fan movement (medium)
