You can solve the problem of the wrong temperature by resetting your fridge’s temperature.

Why Is My Samsung Fridge Showing the Wrong Temperature?

Samsung Fridge Displaying Wrong Temperature

There are a few reasons your Samsung fridge might display the wrong temperature.

Below are the possible causes of your Samsung fridge showing an inaccurate temperature.

  • The most common reason is that the fridge is not calibrated correctly, which can cause the temperature to be off by a few degrees. To fix this, you can adjust the settings on the fridge. 
  • The electricity was either cut off, the power was temporarily lost, or the refrigerator received its initial plug-in.
  • Your Samsung fridge giving inaccurate temperature can also be due to the fridge being in demo or cooling air mode.
  • Another possibility is that something is blocking the sensor, such as food or ice. If this is the case, remove the obstruction and restart the fridge. 
  • Also, your fridge might display the wrong temperature if the door seal is not tight.
  • There may be a problem with the sensor. In this case, you’ll need to contact Samsung for assistance.

  • Reconnect the refrigerator and power it on. Most of the time, your fridge should be working well.

How Do You Check the Actual Temperature of a Samsung Refrigerator?

There are a few ways to check the actual temperature of your Samsung refrigerator.

Here are some ways to do that below.

#1. With the Display Screen

Touching the screen is all it takes to see the actual temperature on the display screen. For example, it shows both the fridge’s and the freezer’s actual temperatures.

Unfortunately, the Flex Zone drawer doesn’t show the actual temperature. Instead, it shows the right or suggested temperature for storing certain things.

Once the refrigerator and freezer adjust to the display, the actual and set temperatures are the same.

If you modify the setting, the display will flash until the actual temperature reaches its setting.

Then, the display briefly shows the actual/set temperature, then turns off until you change it again.

To confirm the actual temperature, switch off the fridge for a few minutes and put it on again after a few minutes.

Then the display screen will show the actual temperature readings of the fridge. If it does not, there may be a problem with the sensor or display.

#2. External Thermometer

One way is to use an external thermometer. Place the thermometer in the fridge and wait a few minutes to see the temperature reading.

You can check with a thermometer by following the step in the paragraph below. First, ensure that the fridge is turned on and set correctly.

Then, place the thermometer in a glass of water inside the fridge and wait for a few minutes.

After a few minutes, check the thermometer to see what temperature it is displaying. The result displayed on the thermometer is the actual temperature.

How Do I Fix My Temperature Sensor in Samsung Fridge?

Before fixing the temperature sensor in your Samsung refrigerator, do the following;

  • Check the power supply to the fridge. If it’s not plugged in or the outlet isn’t working, that could be the problem.
  • Check the control panel settings. For example, make sure the fridge is set to the correct temperature.
  • Clean the condenser coils. These coils help keep your fridge cool, so they can affect the temperature sensor if they’re dirty.
  • Clean the sensor with a cotton swab dipped in rubbing alcohol. Be careful not to damage the sensor while cleaning it.
  • If the sensor is still not working correctly, you may need to replace it. You can find replacement sensors online or at a Samsung service center. Then replace the temperature sensor.

  • First, remove all the shelves in the refrigerator.
  • Disconnect the wiring harness by pressing the locking tab  
  • Take out the bracket in the back panel with a screwdriver.
  • Use a  wire cutter to cut the zip tie holding the wires together
  • Unlock it to remove the wires from its harness to get to the temperature sensor wire.
  • Get a new temperature sensor wire ready to replace the old one.
  • Replace the new temperature sensor wire with the old one in the harness and clip them together. Ensure it’s between the red and white wire.
  • Plug the harness back and use a zip tie to tie them and lock the wires down.
  • Then, put the back panel back and reconnect the wire harnesses to ensure it fits well.
  • Screw all the screws back in using a screwdriver. Then snap the cover back in Replace the shelves in the fridge.

Why Is My Samsung Refrigerator Temperature Display Blinking?

Your Samsung Refrigerator temperature display can blink for a couple of reasons which I’ll explain below and how to remedy it.

Your Samsung fridge is blinking because of the high temperature. It can result from a compromised door seal, the condenser coils being dirty, or the fridge door opening.

In addition, frost buildups and a defective control board from power surges or blackouts can be the cause.

#1. High Internal Temperature

If your refrigerator temperature is very high, it can lead to the display blinking. If it reads above 59°F (15°C), it is too warm to cool and store fresh and perishable goods, which causes the display panel to blink. 

That can happen if someone mistakenly adjusts the fridge’s display panel temperature.

Hot food and the fridge near the wall can help warm it up. So, it will affect the fridge’s ability to cool, resulting in the display blinking.

To remedy the high internal temperature leading to your fridge display blinking; you should do the following;

  • Don’t put hot food or drinks in the fridge because it affects the fridge’s cooling.
  • Provide a 2-in (50-mm) clearance around your fridge to prevent overheating.
  • Once everything is established, modify the display’s temperature.
  • Once the fridge cools, the display panel temperature adjusts automatically. Manually adjust to confirm. Samsung recommends 38°F (3°C) for your fridge. 

#2. Unlocked Fridge

If you leave your fridge door open for an extended time, warm air mixes in with the cool air inside. It makes moisture that warms the refrigerator and lets some of the frost melt.

Soon, the warm air will be picked up by the fridge’s thermostat and make the temperature display blink to let you know something is wrong.

Ensure you close your fridge’s door correctly, and any shelves or bins that will stick out or not allow the fridge to close are placed well. 

#3. Dusty Condenser Coils

Condenser coils process refrigerant to cool your fridge. Without the condenser coil, your fridge won’t cool and may damage other parts.

However, since it’s at the rear of the unit, it quickly gets dirty, which warms condenser coils causing it to malfunction and stopping your fridge from cooling.

If the temperature in your refrigerator is too warm, you should try vacuuming the condenser coils. 

#4. Servicing

If your refrigerator needs servicing or is due for one, it can result in the display blinking. Contact an expert to help with the servicing.

#5. Power Surge or Outage

Surges and outages can damage your refrigerator’s cooling system. As a result, they can damage or malfunction fridge parts.

For example, your fridge enters “Safe Mode” during a power outage which maintains the refrigerator’s temperature, and if it doesn’t, it blinks the refrigerator display.

If the power went out and your fridge started blinking, wait for the temperature inside to stabilize for a day. As soon as it cools down, it will stop blinking; if not, reset your refrigerator.


In summary, your Samsung Refrigerator displaying inaccurate temperature can result from several things, such as a power outage or being in safe mode.

However, you do not need to take your fridge to an expert before you fix it; it’s something you can do yourself.
