What does FF mean on LG refrigerator? Well, fret not, because we’ve got you covered with the explanation. This mysterious code often indicates a problem with the freezer fan, being an abbreviation for “Freezer Fan Error.” Essentially, it suggests that your refrigerator has lost communication with the freezer fan, which could potentially lead to cooling issues.

In this post, we’ll delve into the reasons behind this occurrence and shed light on why it’s essential to address it promptly. Let’s get ready to unravel the secrets of the E FF error code together!

Unraveling the Mystery: What Does FF Mean on LG Refrigerators? Causes and Solutions

There are several factors that can contribute to the E FF error code, including:

  • Leaving the refrigerator door open for an extended period can lead to the infiltration of warm air from the surroundings into the freezer cabinet. This influx of warmer air can cause frost to accumulate inside the freezer, eventually leading to the E FF error code. The refrigerator’s cooling system may struggle to maintain the desired temperature, triggering the error as a protective measure.
  • When ice buildup occurs on the freezer fan, it hampers the fan’s ability to rotate smoothly. The fan’s restricted movement can disrupt the airflow within the freezer, affecting the cooling process. Consequently, the E FF error code is triggered to alert you about the compromised performance.
  • A damaged freezer fan blade can lead to irregular rotations or even cause the fan to seize completely. When the fan fails to circulate the air effectively, the freezer’s temperature may rise, causing the E FF error code to display.
  • The wire harness connects various electrical components within the refrigerator, including the freezer fan. A faulty wire harness, such as damaged or loose wires, can disrupt the communication between the fan and the main control board. As a result, the refrigerator may not receive the necessary signals from the fan, leading to the E FF error.
  • In some instances, the E FF error code may be triggered due to a malfunctioning freezer fan itself. A faulty fan can experience motor issues or bearing problems, preventing it from operating correctly. As a vital component for cooling, a dysfunctional fan can lead to inadequate temperature regulation, prompting the error code.
  • The main control board of the refrigerator is responsible for processing and sending signals to various components, including the freezer fan. If the main board malfunctions or experiences communication errors, it may fail to send or receive signals appropriately, causing the E FF error to appear.

If you encounter the E FF error code on your LG refrigerator, don’t worry; we’ve got a step-by-step troubleshooting guide to help you resolve the issue:

  1. First, defrost the freezer evaporator to remove any ice buildup around the fan. Throwing the ice will allow the fan to rotate smoothly and restore proper airflow within the freezer, resolving the issue.
  2. If the fan blade is damaged, it will need to be replaced.
  3. Inspect the wire harness for any signs of damage or loose connections. If you identify any issues, repair or replace the wire harness as needed to restore proper communication between components.
  4. Ensure the freezer fan is not obstructed and can move freely. You can do this by gently trying to rotate the fan blades. If the fan is stuck or doesn’t move easily, it’s a clear indication that the fan needs to be replaced. However, if the fan moves smoothly, proceed to the next step.
  5. Inspect the fan shroud for any misalignment that might prevent proper fan operation. Make sure it is correctly positioned and secured in place. A misaligned shroud can obstruct the fan’s airflow, leading to cooling problems. Adjust or reposition the shroud if necessary.
  6. To check the freezer fan’s electrical performance, use a multimeter to measure the feedback voltage between GND (ground) and FG (feedback). The voltage reading should be approximately around 2.4 Vdc. If the measured value deviates significantly from this range, it indicates a faulty fan. In such a case, you should replace the fan with a new one.
  7. Next, evaluate the main control board’s performance by measuring the main voltage between VCC (power supply) and GND (ground). The voltage reading should be approximately 12 Vdc. For refrigerators with a 4-wire freezer fan, also measure the PWM (pulse width modulation) voltage between PWM and GND. The PWM voltage should typically range from 1.2 to 4.6 Vdc. If the voltage readings are outside the expected range, it may indicate an issue with the main board.
LG refrigerators error codes freezer fan


If you see an E FF error code on your LG refrigerator, it means there’s a problem with the freezer fan.

Common causes include:

  • Ice buildup on the fan
  • Door left open
  • Damaged fan blade
  • Faulty wiring
  • Fan motor failure
  • Main control board issue

To fix it:

  • Check the fan: Ensure it’s spinning freely, look for ice buildup around the fan, and defrost if needed.
  • Check for electrical problems by testing voltages and wiring connections.
  • Replace faulty parts: If necessary, replace the fan, wiring, or control board.

FAQs about the E FF “Freezer Fan” Error Code on LG Refrigerators:

The E FF error code indicates a problem with the freezer fan, which could lead to cooling issues.

The error can be triggered by leaving the left door open for too long, ice buildup on the fan, a damaged fan blade, a faulty wire harness, a faulty freezer fan, or a malfunctioning main control board.

To resolve the issue, check the freezer fan for movement and alignment, defrost the freezer, and inspect the wire harness. If necessary, replace the freezer fan motor.

To prevent the E FF error, ensure doors are properly closed, avoid leaving them open for long, and perform regular maintenance, such as defrosting the freezer approximately every 8 months.
