Common Error Codes and Their Meanings

Understanding the error codes displayed by your refrigerator can be the key to quick and efficient troubleshooting. Let’s delve deeper into the common error codes for popular refrigerator brands and what they signify.

1. LG Refrigerator Error Codes

  • FF Error Code: This error is related to the freezer fan, which circulates cold air throughout the freezer and refrigerator compartments. If this fan encounters issues, it can lead to uneven temperatures, with some areas getting too cold while others may not be cold enough. The FF error code may suggest a blockage, a fault in the fan motor, or a problem in the control circuit.
  • HS Error Code: The HS code points to a malfunction with the defrosting sensor in the freezer. This sensor plays a critical role in managing the defrost cycle, preventing excessive ice buildup. A faulty sensor can lead to poor cooling performance and overfreezing. Replacing the sensor is usually the recommended fix.
  • DH Error Code: Indicates a problem within the defrost system, specifically with the defrost heater. This component melts away any frost that accumulates on the evaporator coils. If it fails, frost will continue to build up, blocking airflow and reducing cooling efficiency. This issue might require replacing the defrost heater or troubleshooting the control circuit that powers it.
  • CF Error Code: This code alerts you to a malfunction with the condenser fan motor. The condenser fan helps in dissipating heat from the refrigerator’s condenser coils. If this fan is not working correctly, your refrigerator might not cool efficiently, leading to warmer compartment temperatures. Cleaning the fan and removing any obstructions might resolve the issue, but in some cases, the motor may need to be replaced.
  • ER FS: Signifies a flow sensor error, which can compromise the refrigerator’s cooling system by affecting its ability to monitor and adjust the coolant flow. This error might be due to a faulty sensor or issues within the control board. Troubleshooting may involve sensor replacement or deeper electrical diagnostics.

2. Samsung Refrigerator Error Codes

  • 1E or SE: This communication error signals a disconnect or failure in the communication line between the refrigerator’s control panel and its main control board. This could be due to a loose wire, a faulty control panel, or a malfunctioning main board. Reseating connections or replacing the defective parts are common solutions.
  • 22E or 22C: Indicates a problem with the refrigerator’s fan motor or a physical blockage that prevents the fan from spinning freely. This fan is essential for distributing cool air throughout the unit. Removing the obstruction or replacing the fan motor are potential fixes.
  • 5E or SE: This code is related to a defrosting issue, pinpointing a problem with the refrigerator defrost sensor. The sensor’s failure can disrupt the defrost cycle, leading to excessive frost buildup and cooling issues. Sensor replacement is typically required to resolve this error.
  • PC-ER: Highlights a communication problem between the control board and the display panel. This could affect the ability to adjust settings or read the temperature display. Checking for loose connections or a faulty display panel might be necessary steps to address this error.

3. Whirlpool Refrigerator Error Codes

  • CF: This error code indicates a compartment temperature feedback signal error, suggesting the control board isn’t receiving the correct signals from the temperature sensor. This could lead to improper cooling settings. Troubleshooting may involve checking sensor connections or replacing the sensor.
  • dE: The demo mode error is particularly unique as it doesn’t indicate a malfunction but rather that the refrigerator is in a non-cooling mode used in showrooms. Exiting demo mode involves a specific combination of control panel inputs, which can vary by model.
  • PO: A power outage error code that reminds you to check if the refrigerator has been disconnected from power or if there was a recent outage. After restoring power, it’s essential to verify that the refrigerator returns to its normal operation, including cooling to the set temperatures.

4. GE Refrigerator Error Codes

  • TC: This temperature control error suggests an issue with the temperature sensor or the control board’s ability to regulate the internal temperature. This could lead to the refrigerator running too cold or too warm. Replacing the faulty temperature sensor or troubleshooting the control board may be necessary.
  • LC: Indicates a low side refrigerant leak, which can significantly impact the refrigerator’s cooling efficiency. Such leaks require professional repair to locate and seal the leak and to recharge the refrigerant system properly.
  • HC: Similar to the LC error, the HC code points to a high side refrigerant leak. This type of leak can also degrade cooling performance and requires professional intervention for repair and refrigerant recharge.Troubleshooting and Resolving Issues

Resetting the Refrigerator

Many issues indicated by error codes can be resolved by simply resetting the refrigerator. This can be done by unplugging the unit for a minute and then restoring power. If the error persists, further troubleshooting or a repair service may be necessary.

Specific Error Code Troubleshooting

  • Communication Errors (1E, SE, PC-ER): Check the connections between the control panel and the main control board. A loose connection can cause communication errors. If reconnecting does not resolve the issue, a repair service may need to replace the faulty component.
  • Fan and Motor Errors (FF, CF, 22E): Check for any obstructions around the fan blades and ensure they are clean. If the error persists, the fan motor may need replacement.
  • Sensor and Defrost System Errors (HS, DH, 5E): These errors often require replacing the faulty sensor or component in the defrost system. It’s advisable to contact a professional repair service for these repairs.
  • Refrigerant Leak (LC, HC): Refrigerant leaks are serious issues that affect the refrigerator’s cooling efficiency. These require professional attention to locate the leak, repair it, and recharge the refrigerant.

Preventive Measures

  • Regular Maintenance: Regularly cleaning the coils and ensuring the refrigerator and freezer doors seal properly can prevent many issues.
  • Avoid Overloading: Overloading the refrigerator can obstruct airflow and put extra strain on the cooling system, leading to errors.
  • Proper Power Supply: Ensure your refrigerator is connected to a stable power supply to avoid power surge-related errors.


Understanding refrigerator error codes is essential for diagnosing issues and maintaining the efficiency of your appliance. While some errors can be resolved with simple resets or troubleshooting steps, others may indicate more serious problems requiring professional repair services. Regular maintenance and being mindful of your refrigerator’s operation can help minimize the occurrence of these errors. If you encounter a persistent error code, contacting a certified repair service is the best course of action to ensure your refrigerator continues to operate correctly.
