In this guide, we will provide an overview of common Samsung top-mount freezer refrigerator error codes that may appear on your display panel, main board, or inverter board, as well as simple troubleshooting steps you can take to fix the problem and get your fridge back to working properly.
Troubleshooting Samsung Top-Mount Freezer Refrigerator with LED Blinking Codes
Locating the Warning LED:
- Identify the main and/or inverter board: Look for a circuit board, typically located behind a metal cover, that might require unscrewing.
- Access the Back Panel: Carefully remove the lower rear panel of your refrigerator by unscrewing any screws and gently pulling it outward.
- Find the LED: Locate a small LED (usually red or orange) on the inverter board or possibly the main board nearby.
Understanding the Blinking Pattern:
- Observe the blinks: Watch the LED closely and count the number of blinks in a single cycle. Each blink sequence represents a specific error code.
- Decode the error code: Refer to a separate error code list below. This list should detail the meaning of each blink pattern. Match the number of blinks you observed to the corresponding explanation in the list to diagnose the error code.
Additional Note:
- The LED will continue blinking until you unplug the refrigerator. This allows you to easily see and record the error code for troubleshooting.

Samsung Top-Mount Freezer Refrigerator Error Codes: Self-Diagnosis mode
How to place the refrigerator into self-diagnosis:
Press and hold the “Freezer” and “Fridge” buttons simultaneously for 12–13 seconds. You will hear a dingdong sound, which indicates that the self-diagnosis mode has been successfully activated.
When the appliance enters self-diagnosis mode, all LEDs will be off, and:
- If there is no error, the temperature LED “XX°C” on the control panel will return to normal operation after 12–13 seconds.
- If there is an error, the temperature LED “XX°C” on the control panel will be blinking or flashing with a dingdong sound.
- The error code remains for 1 minute, then the refrigerator will return to normal operation.
notice: *only for the models with ice maker
- When the ice On/Off icon flashes during the self-diagnosis mode,
- And there is no ice maker installed in the refrigerator; it doesn’t indicate an error.
- But if there is an ice maker installed in the refrigerator, it indicates that something is wrong with the ice maker and needs to be checked.
How to exit self-diagnosis mode:
- To exit the mode:
- Method 1: When there is an error, the self-diagnosis will automatically exit after one minute.
- Method 2: When there is no error, the self-diagnosis will automatically exit after 12 seconds.
- Method 3: Press and hold the “Freezer” and “Fridge” buttons simultaneously for 12 seconds.
- Method 4: Unplug the refrigerator.
