Ordinarily, when your Samsung refrigerator shows error messages, it suggests that a reset is needed. We advise consulting our comprehensive guide that provides crucial details about frequently emerging error messages and offers a step-by-step procedure for various reset methods.

General Precautions

If you are determined to reset your Samsung refrigerator, make sure you know what you’re doing. Unplug the fridge from the AC socket before doing anything to it. Also, fridges contain noxious gases within the compressor so never interfere with that.

At SmartHomePerfected we always advise readers not to undertake any work they are not competent in performing and if in any doubt, it is best to seek the assistance of a professional.

Each Samsung refrigerator model is different, so if the below troubleshooting steps do not work, then you can access the specific model's user manual here.

How to power reset your Samsung Refrigerator

From time to time, users might find their refrigerators have started acting up. This may happen after a sequence of abrupt power surges, after a power outage or after heavy storms.

A Samsung fridge might suddenly start displaying the wrong temperature instead of the default factory temperature. If users have food stored inside, they should take it out.

If every other solution fails, a power reset can restore the refrigerator to all its default settings.

  1. Turn the refrigerator off using the “Power Button”.
  2. Look at the back of the refrigerator, locate the power cord, and unplug it.
  3. Keep the refrigerator turned off for a few hours.
  4. Plug the refrigerator back in.
  5. Use the Power Button to turn it back on.
  6. The refrigerator should work fine now.

How to reset your Samsung Refrigerator from shop/demo mode

The Shop/Demo mode serves a special purpose. When a Samsung refrigerator is in the shop, before it’s purchased, the retailers enable this mode to ensure less energy is consumed.

Having this mode turned on keeps all parts of the fridge working, except for the cooling system. Once enabling this mode, the fridge will have its interior lightings and display panel working, allowing retailers to show potential buyers how it works.

However, after a buyer makes a purchase, the Shop/Demo mode must be turned off. If it stays turned on, all the food in the fridge will go bad!

  1. Check if the “Cooling Off Mode” is flashing.
  2. If yes, find two buttons located on the left side of the refrigerator's display panel (as per the video).
  3. Press and hold these two buttons for 5-10 seconds.
  4. Make sure the two buttons are pressed at the same time. The refrigerator will make a different sound than when a single button is touched.
  5. After releasing the buttons, wait a few moments.
  6. If the display panel starts projecting the Cooling Off Mode message again, repeat the steps until it is disabled.

How to set or reset the temperature on a Samsung Refrigerator

By default, all Samsung refrigerators are set to 40 degrees Fahrenheit or below. This temperature is optimal to prevent the food inside from accumulating bacteria.

However, under special circumstances, users need to bring down the temperature in their fridge. For example, if they intend to keep dairy products, the optimal temperature is 34 degrees.

If you have never reset the temperature on a Samsung refrigerator before, don’t worry. All you have to do is tweak a few bars to set the fridge to the desired temperature.

  1. Locate the control panel.
  2. Press the Fridge button to set the desired temperature.
  3. Wait a few seconds, the cooling system will slowly adjust to the newly set temperature.
  4. Once it’s done, the display panel will show the new temperature.
  5. It might take some time before the fridge stabilizes to the new temperature.
  6. It is suggested to check the temperature again after a day.

How to reset the control panel after a power outage

All the latest Samsung fridges come with a control panel. Using the control panel, users can adjust the settings to their requirements, settings such as the temperature, lighting, energy-saving, power freezing, and ice-dispenser.

Moreover, the control system also displays key information about the fridge's health. This is why users might panic if the control panel stops displaying information or the buttons stop working.

If a user encounters an error with the refrigerator after a power outage, a Control Panel reset will solve the problem.

  1. Check if the Child Lock is enabled.
  2. If it is on, disable it. This will fix the control panel error.
  3. If it still doesn’t work, a Control Panel Display Reset will do the trick.
  4. Locate the reset switch. You will find it at the top corner of the right door.
  5. Use it to turn off the display.
  6. Wait for a few seconds and press it again to turn it back on.
  7. If successful, the Samsung logo will appear on the screen and the rest will be complete.

How to reset the Ice Maker

Along with storing food, Samsung refrigerators are also equipped to produce ice. In fact, with the latest models, users can increase the speed of ice production inside the refrigerator.

Whether you like your drink on ice or need ice for a special dish, you can’t afford to have the Ice Maker not working for too long.

If your Samsung fridge stops producing ice, or if you detect any drop in the production of ice, resetting the Ice Maker will fix the problem.

  1. For “Flex Tray”, open the fridge, lift the ice machine and pull.
  2. Find the test switch (under the Ice Maker).
  3. Press and hold it for 3 seconds. This will reset the ice maker.
  4. The ice maker might first dump any remaining ice before initiating a water refill.
  5. For “Heated Tray” Ice Makers, open the freezer, hold the ice bucket by its sides, squeeze and lift it.
  6. This should separate the ice bucket from the main ice producing unit.
  7. Locate the test switch. You will find it on the top-left, adjacent to the sensor arm joint.
  8. Press and hold the test switch for a few seconds.
  9. For models that came after 2010, a chime sound will be heard if the process is complete.

How to reset the wire harness between the door and control unit

If your refrigerator display is projecting a message that says it has identified a wire harness error, it means the door and the central control unit are failing to communicate with each other.

Usually, a “PC Er” message signifies this error. If this happens, a proper wire harness reset will fix the problem.

Unless users fix this error, the door might not close properly, and as a result, the food inside the fridge might go bad.

  1. Turn the fridge off.
  2. Locate the power cord and unplug it. You will find it at the back of the fridge.
  3. Find the wire harness.
  4. Separate the wire harness, wait for a while, and reconnect.
  5. Go ahead and start the fridge. The error code should disappear.

How to reset the water filter and filter light

Water filters ensure you don’t drink contaminated water from the fridge dispenser. They reduce impurities and make the water drinkable via a chemical, biological, or a physical barrier.

Luckily, many Samsung refrigerators come with built-in water filters. Water filters force the water through an activated carbon compartment inside the refrigerator and clean it.

If the refrigerator is used for drinking water, users can’t afford to have the water filter giving the wrong readings for long.

  1. Take out the old water filter and replace with a new one. This is typically located in the center of the fridge and has a twist cap.
  2. Resetting the filter indicator depends on the model you have. Try any of the three options below.
  3. Press and hold the Alarm button for 3-5 seconds.
  4. Press and hold the Ice Type/Water button for 3-5 seconds.
  5. Press and hold the Ice/Water button for 3-5 seconds.
  6. This should reset the water filter indicator.
