Testing Samsung Refrigerator Components with the Display Panel: A Practical Tool for Technicians
Samsung side-by-side refrigerators include a built-in test mode that allows technicians to check the performance of the unit’s core components without the need for complex tools. This method is a fast and precise solution for diagnosing technical issues and helps you correctly identify the root cause of a malfunction. This article is a complete guide to testing Samsung refrigerator components using the display panel.
How to Enter Test Mode

To enter the diagnostic mode, first ensure the refrigerator and freezer doors are closed. Then, according to the provided instructions, simultaneously press buttons number 1 and 2 for 10 seconds. The display will go blank for a moment, indicating that you have entered the test mode.
Immediately after, by pressing button number 3, you can cycle through the different test modes. These modes are divided into three main groups.
Test Modes for Samsung Refrigerator Components with the Display Panel
Mode 1: For Samsung Refrigerators with an Inverter Compressor
With each press of button number 3, a new mode is activated to test a specific function.
Testing Samsung Refrigerator Components with the Display Panel (Compressor, Fan, Defrost)
| Test Code | Compressor Status | Fan Status | Function |
| FF1 | On (3600 RPM) | On (if door is closed) | The compressor and fan operate at maximum speed. Defrost is inactive. |
| FF2 | On (2450 RPM) | On (if door is closed) | The compressor and fan operate at medium speed. Defrost is inactive. |
| FF3 | On (2050 RPM) | On (if door is closed) | The compressor and fan operate at low speed. Defrost is inactive. |
| rd | Off | Off | Refrigerator defrost is activated. The refrigerator defrost heater should get hot. |
| fd | Off | Off | Freezer defrost is activated. The freezer defrost heater should get hot. |
| cancel | Off | Off | The refrigerator exits test mode and returns to normal operation. |
Mode 2: For Samsung Refrigerators with a Rotary or Inverter Compressor

| FF | On | On (if door is closed) | The 3-way valve is set to the refrigerator position. Defrost is inactive. |
| of-r | On | On (if door is closed) | The 3-way valve is set to the freezer position. Defrost is inactive. |
| rd | Off | Off | Refrigerator defrost is activated. The refrigerator heater should get hot. |
| fd | Off | Off | Freezer defrost is activated. The freezer heater should get hot. |
| cancel | Off | Off | The refrigerator exits test mode and returns to normal operation. |
Mode 3: For Samsung Refrigerators that Do Not Display a Test Code

Important Notes on UsingTesting Samsung Refrigerator Components with the Display Panel
- When performing tests, pay close attention to the sound of the components operating (such as the fan or compressor turning on).
- To check the defrost heater, you can carefully check its temperature to ensure it is working correctly.
- Always exit the test mode using the cancel option to return the unit to normal operation.
- A continuous beep will sound from the unit while in test mode, indicating that it is in the diagnostic state. This beep will only stop once the unit returns to normal operation (by using the cancel option).
- Leaving the refrigerator in test mode for an extended period can cause severe and costly damage to the internal components.
- This procedure is highly sensitive and, due to its technical complexity, must be performed by a specialist.
- If the component’s performance during any of the steps does not match the descriptions in the tables above, that specific component is either faulty or malfunctioning.
- Some Samsung refrigerators have four buttons, but the operation remains the same using the two bottom buttons on the left and right.
Conclusion
Testing Samsung Refrigerator Components with the Display Panel
Using the internal test mode is a powerful tool for any Samsung side-by-side refrigerator technician. By using this method, you can save time and energy while performing diagnostics with greater accuracy. Understanding these test codes and their functions allows you to quickly identify faulty components and perform a more professional and reliable repair. Learning how to test components using the display panel will significantly increase your repair speed, accuracy, and the quality of your work.
