James is a Master Electrician with over 30 years of experience. We do not use AI for the content of our articles.

Samsung refrigerators display error codes whenever the control board detects a problem with a sensor, fan, ice maker, compressor, or electronic component.

Use this guide to identify what each error code means, what usually causes it, and the steps you can take to fix it yourself before calling for service.

But before diagnosing any code, unplug the refrigerator for 5 minutes and reconnect power. Many temporary faults clear after a power-off/on reset – and most Samsung refrigerator resets take less than 10 minutes with no tools needed.

Note: This guide applies to most Samsung French door, side-by-side, top freezer, bottom freezer, Bespoke, and Family Hub refrigerators.
The information here is based on Samsung service documentation, published technical information, and common repair procedures used by appliance technicians.
Because error code definitions can vary slightly between models, always confirm troubleshooting steps using your refrigerator’s service manual when available.

Here are the top 10 most common Samsung refrigerator error codes. Click on the links in the table to jump down to fuller explanations and procedures.

Later in this article I have a full list of all codes.

How to Read Samsung Error Codes

Error codes can be all numbers, all letters, or a combination of both. They are usually no more than 3-4 digits in length.

You’ll notice that many error codes have a common number with a C or E suffix (e.g. 40C and 40E). Different models use different suffix letters to designate the same error.

Also, some older models do not use alphanumeric codes at all, but rather flash LED indicators in patterns.

How to Reset Your Samsung Refrigerator (Do This First)

Before troubleshooting any Samsung refrigerator error code, perform a reset. Temporary software glitches, communication faults, and power interruptions can sometimes trigger error codes even when no component has actually failed.

Resetting the refrigerator may clear the code and restore normal operation. Most Samsung refrigerator resets take less than 10 minutes and require no tools.

Method 1: Perform a Hard Reset

A hard reset is the simplest and most effective reset procedure for most Samsung refrigerators.

1. Unplug the refrigerator from the wall outlet.
2. Leave it disconnected for at least 5 minutes.
3. Plug the refrigerator back in.
4. Allow several minutes for the control boards to restart and communicate with all sensors and components.

If the error code does not return, the issue may have been caused by a temporary electronic fault or power interruption.

Method 2: Reset the Control Panel

Some Samsung models allow you to reset the display panel without disconnecting power.

1. Locate the Power Freeze and Power Cool buttons on the control panel.
2. Press and hold both buttons simultaneously for approximately 10 seconds.
3. Release the buttons when the display flashes or the refrigerator chimes.

The display should restart and any temporary display errors may clear.

Note: Button combinations vary by model. For example, some other combos are Energy Saver + Power Freeze, or Fridge + Freezer. Consult your owner’s manual if these buttons are not present.

Method 3: Clear an Error After a Power Outage

Following a power outage, some Samsung refrigerators may display communication-related codes such as 88 88, PC ER, or PC CH.

1. Verify that household power is stable.
2. Perform a hard reset by unplugging the refrigerator for 5 minutes.
3. Restore power and allow the refrigerator to complete its startup sequence.

In many cases, these codes disappear once communication between the refrigerator’s control boards is restored.

Method 4: Exit Demo Mode (OF OF / O FF)

If your display shows OF OF or O FF, your refrigerator is in Demo Mode and is not cooling. This is not a malfunction — it requires a specific button combination to exit instead of a standard reset.

Press and hold Energy Saver and Power Freeze simultaneously for 5 seconds. The display will show the mode indicator for a brief moment before returning to normal temperature readings. On some models the combination is Energy Saver + Lighting, while others use Fridge + Freezer.

Once exited, the refrigerator will begin cooling normally within 30-60 minutes.

If the Error Code Returns

If the same error code reappears immediately after resetting, the refrigerator is detecting an active fault. In that case, continue to the troubleshooting section for your specific error code.

A reset can clear temporary software or communication issues, but it will not permanently fix failed sensors, defective fans, wiring problems, control board failures, or other mechanical and electrical faults.

OF OF / O FF, AP,  – Non-error / Mode Codes

These codes are not indicating errors, but rather display modes of operation or functionality.

OF OF / O FF – Cooling Off Mode

What the code means

OF OF (or O FF on some models) indicates the refrigerator is in Cooling Off Mode, also known as Demo Mode. This is not an error code. Cooling is intentionally disabled while the display, lights, and other functions remain operational, making it ideal for showroom displays.

Common causes

• Demo Mode was accidentally enabled using the control panel.
• The refrigerator was recently installed or moved from a retail display.
• Buttons were pressed unintentionally during cleaning or operation.

How to fix it

1. Confirm the refrigerator is in Cooling Off Mode by checking for the OF OF or O FF display.
2. Exit Demo Mode using the button combination for your specific model (see Method 4 above).
3. Wait a few minutes for the compressor and cooling system to restart.
4. Verify that the refrigerator and freezer begin cooling normally.

Note: The button combination to disable Cooling Off Mode varies by model. Refer to your owner’s manual if the standard method doesn’t work.

AP – WiFi Setup Mode

What the code means

AP indicates the refrigerator is in WiFi Setup Mode (Access Point Mode). This is not an error code. The refrigerator has enabled its temporary wireless network so it can be connected to your home WiFi using the SmartThings app.

Common causes

• WiFi setup mode was enabled to connect the refrigerator to a wireless network.
• The refrigerator was reset or disconnected from the home network.

How to fix it

1. Complete the WiFi setup process using the SmartThings app if you want to connect the refrigerator.
2. If you don’t want to use WiFi, exit AP mode by pressing the appropriate button combination for your refrigerator model.
3. Wait a few moments for the display to return to the normal temperature readout.

Note: The button combination to exit AP mode varies by model. Refer to your owner’s manual if you’re unsure how to disable it.
