Samsung Refrigerator 5C or 5E Error Code

So, let’s take a closer look at how to fix the Samsung refrigerator 5C or 5E error code and get your fridge back to its optimal functionality in no time.

The Ultimate Troubleshooting Guide to Fixing the Samsung Refrigerator 5C or 5E Error Code

Understanding the Samsung Refrigerator 5C or 5E Error Code: Explained

The 5C or 5E error code on a Samsung refrigerator typically indicates a problem with the fridge cabinet defrost sensor. This error is an abbreviation for “Fridge Defrost Sensor Error,” which means that the appliance failed to receive a valid value from the defrost sensor due to an open or shorted circuit on the line between the main board and the sensor.

Let’s look into the factors that can contribute to the appearance of this error code:

The Role of Moisture in Triggering the 5C Error Code on Your Samsung Refrigerator:

  • One common reason for the 5C error code is the accumulation of moisture around the defrost sensor or its wire connections. Moisture can cause electrical disruptions, leading to faulty readings or signal transmission issues between the sensor and the main board.

Faulty Sensor Wire Harness Connection and the 5C Error Code:

  • If the wire harness connecting the defrost sensor to the main board is not securely connected or has become damaged, it can result in a poor electrical connection. This, in turn, can trigger the 5C error code as the main board fails to get an accurate value from the defrost sensor.

The Culprit Behind the 5C Error Code:

  • The fridge defrost sensor itself may be faulty. If the sensor is defective or damaged, it may not provide the correct temperature readings to the main board, leading to the 5C or 5E error code.

Is your main board at fault? Investigating the 5C Error Code Causes

  • In some cases, the main control board of the refrigerator could be malfunctioning. If there is an issue with the board’s circuitry or communication pathways, it may not be able to interpret the value from the defrost sensor correctly, resulting in the 5C or 5E error code.

Here are the solutions to troubleshoot and resolve the 5C or 5E error code on your Samsung refrigerator:

  1. Carefully inspect the sensor area and its connections. If you find any moisture, use a soft cloth to dry the affected parts thoroughly.
  2. Ensure the wire harness connecting the defrost sensor to the main board is securely attached. A loose or damaged connection can lead to inaccurate readings and trigger the error code.
    • If you notice any issues with the wire harness, reattach it securely or consider replacing it if necessary.
  3. If the error persists, it’s essential to test the fridge defrost sensor’s functionality. Use a multimeter set to measure resistance and check the sensor’s resistance value. At 25°C (77°F), the resistance value should be around 5 kilo ohms. If you get a significantly different reading or an open or short circuit indication, the sensor may be faulty and require replacement.

  1. If all the previous steps haven’t resolved the issue, it’s time to test the main control board. With the power connected, use a multimeter to measure the voltage value at the fridge sensor with its connector disconnected. The reading should be approximately 4.98 volts. Next, reconnect the sensor’s connector and measure the voltage again; it should be around 1.67 Vdc at 25°C (77°F).
    • If the voltage readings are outside of these ranges, it indicates a malfunctioning main board, which may need replacement.

The 5C or 5E error code on your Samsung refrigerator is related to the fridge defrost sensor. To resolve this issue, check for moisture buildup, inspect the sensor wire harness connection, and test the sensor and main board using a multimeter.

Frequently Asked Questions (FAQ) about Samsung Refrigerator 5C or 5E Error Code

It is not recommended to continue using the appliance when the 5C or 5E error code is displayed. The error indicates a potential issue with the defrost sensor, and using the appliance in this state may lead to further problems. It’s best to address the error promptly to avoid any potential damage.

To remove moisture, use a soft cloth to gently dry the sensor area and its connections.

  • Ensure it is completely dry before reconnecting.
  • Make sure to disconnect the power supply to the fridge before performing any repairs.

You can try troubleshooting the 5C or 5E error using the provided steps.

The defrost sensor monitors the temperature inside the fridge cabinet evaporator and signals the main board to initiate the defrost cycle when necessary, preventing frost buildup.

The occurrence of the 5C or 5E error code depends on various factors. It’s relatively uncommon, but if moisture or sensor-related issues arise, it may trigger the error.

If your refrigerator is under warranty, contact Samsung’s customer support or the Samsung authorized service center immediately. Warranty coverage may include repairs or replacements of faulty components, depending on the terms and conditions. Avoid attempting repairs yourself to prevent voiding the manufacturer’s warranty.
