In this article, we will show you the 5 most common issues.

But let’s start with some recent complaints from our visitor and then we will explain what you can do to fix these issues.

Here is what Darren says: I own a Samsung refrigerator that seems to have a problem with cooling in the fridge compartment, despite being several months old. The temperature is fluctuating and sometimes Samsung fridge not cooling at all.

I have tried doing everything I know to get it running normally again but no luck. Does anyone have an idea about what can possibly be wrong and how that can be fixed? Or is there a way it can be reset back to its initial state?

What causes Samsung fridge not cooling, but freezer works. 

The evaporator coils are frosted over:

When the evaporator coils get covered with frost, evaporator fan unable to circulate cold air within the fridge due to blockage and fridge will not be cooling. Initial problem related with defrost cycle.

Sometimes, the problem can be solved by changing the defrost temperature sensor (but its not guaranteed)

There are actually 2 identical temperature sensors. But you will need one with the white connector on the right side of the fridge.

If you see ice build-up on the back wall where is said “Twin Cooling” of your fridge or maybe you hear noise coming from the fridge, but when you open the door noise just gone?

That’s mean you have an issue with condensation which accumulates behind that panel and eventually becoming ice.

In this case, you need this Drain Repair Kit above and here is the video below what you need to do.

Evaporator fan frosted over:

Some people may complain about “Why Samsung fridge fan not working?” The main purpose of the fan is to circulate the cold air in the fridge.

But when your Samsung fridge not cooling, one of the reasons for that is that your evaporator fan blocked by ice.

You need to check your evaporator fan to make sure it’s working or not.

Samsung fridge evaporator fan  not spinning

If you have a french-door refrigerator, close the left door and put an ordinary magnet on the right side of the fridge to simulate the right door closing.

After a couple of seconds, the evaporator fan should start spinning.

If you don’t hear the fan running, most likely fan blades blocked by ice.

Defective defrost heater :

Under normal circumstances the defrost heater assembly (you can get one here) is responsible for defrosting any frost that been formed on the evaporator coils in the refrigerator, whose function is to allow cold air to freely flow thereby leading to the freezer cooling.

However, when the defrost heater assembly is not functioning accordingly, excess frost will build upon the evaporator coils, as a result, the airflow will be restricted, which will result in the fridge not cooling. 

Defective thermistor or temperature sensor:

When working properly this component keeps in check the temperature of the refrigerator and transmits the information on the temperature reading to the control board so that appropriate power can be supplied to the evaporator fan as well as the compressor for effective cooling in return.

But when the thermistor is defective both the compressor and the evaporator fan may not work properly.

Defrost thermostat failure:

This component allows the power to flow to the heater.

When its failed, power will not flow and heater will not able to heats up and melt ice or frost which may build up on the evaporator coils.

What can be done to help the freezer start cooling again? 

Apart from replacing any components found defective, the following actions can be taken to fix the inability of the fridge to cool. 

In most cases, the inability of the Samsung fridge to cool is as a result of having excess ice frosting over the evaporating coils as well as the fan.

Therefore, one can easily initiate a FORCED DEFROST mode by pressing FREEZER and LIGHTING or ENERGY SAVER and FRIDGE buttons at the same time for 8 seconds.

Once you will hear one chime sound, press the LIGHTING button several times after that, until you will see Fd on the display.

This action activates the defrost element and melt the ice. 

To exit the Forced Defrost mode you can simply unplug power from the wall or wait 20 minutes till forced defrosting will be done.

In a nutshell, Samsung fridge inability to cool is one of the most inconveniencing challenges faced with the brand.

Among the notable causes include the malfunctioning of various components that work together as a team to bring about cooling in a freezer, such as a compressor, defrost control board and the evaporator coils among others. 

Nevertheless, the Samsung fridge not cooling is not a permanent problem.

Rather, this is something one can easily fix by simply making diagnostic tests on the components suspected to be defective, such as the ones mentioned above and have them replaced or even repaired where possible.

Therefore, don’t let the Samsung fridge not cooling give you a headache when there is something you can do about it to bring back that peaceful mind and the beauty of the fridge.

  1. I have a Samsung French door Frig Model RF4287 HARS. After power outages, our Samsung fridge shows the error code 2E. My fridge stays arou9nd 40 degrees. I have it set for 34 degrees. Do I have a bad sensor?

    Reply
    • Hi George, according to the information i have, “2E” error code related to fresh food temp compartment sensor, probably have a bad connection or open circuit. Try to reset by pressing Lighting and Energy Saver buttons at the same time for 10 seconds.

    • Hi. I am trying to figure out why does it feel like the fridge is not cool enough in my Samsung French Door Refrigerator & the freezer is not getting cold at all. I already checked my coils, circuit board, & fan. The coils are not frozen & the fan is running, but it seems like it never shuts off. The red light in the circuit board is a still red light-no flashing. I also reset the defrost mode by pressing the lighting & energy button for 10 secs to reset. I guess I will check the inside where the Twin Cooling Plus is located to see if it is frozen inside, but I’m not sure how to reset the whole refrigerator? Any other suggestions?

      • Hi Angel, if it’s not cooling, most likely it’s frozen behind that panel where it says Twin Cooling. Can you see some frost build up in the vent rectangular openings on that panel?

        Reply
          • Hi Robert, you can try this….turn power OFF to the fridge at least for 24 hours, with the door open, and let it defrost by itself. After that turn power ON and if fridge will work fine after that (at least for a week), most likely there was frosted behind the back panel where is says “Twin Cooling” . In most cases it caused by moisture build-up behind that panel. Or in rare cases, you have an issue with defrost thermostat or heater.

  2. My Samsung cooling plus is freezing up on the back board. Tech was here and defrosted it changed me $180.00 fridge is still freezing up behind the cover board now he wants to put in a new cover and charge me over $300.00 is something wrong with this picture or is this the right repair to do?

    Reply
    • Hi Tracy, unfortunately this repair procedure not working for every Samsung model. If technician wants to put new cover, that’s ok, but it’s no guarantee that it will solve the problem. Ask him about warranty for their job and receipt as well. Cause dealing with Samsung fridges issues, unfortunately , very tricky. Good luck

    • Hi Bob, when you pulled out evaporator cover, did you see any ice covering drain hole? if yes, then its not draining properly and some moisture evaporates and turns into the ice. You need to check drain rubber grommet behind the fridge to make sure its not clogged. its recommended to replace it with a new Drain repair Kit (see it in the post)

  6. Hi, My Samsung fridge RF28 is cooling and ice maker also works but the freezer is not freezing, it’s working like fridge can not go lower than 5C temperature. Any idea?

    Reply
    • With a Samsung, usually it’s opposite, freezer is cooling , the fridge is not. Well, check if you have frost build up, behind back panel in the freezer. If yes, it could be defrost heater or thermostat. That frost or ice restricting air circulation in there.

  7. Same Fridge not cooling issue, 2 years old, RF23J9011SG. No frost, clear coils. Fridge cools down to 34 degrees properly then the display never changes as the fridge warms up. Compressor does not go on again to cool the refrigerator contents down. Temperature sensors tested OK in the fridge (both). Fan tests perfect. Power cycle the refrigerator and the temperature now reads 55 degrees, compressor comes back on after 5 minutes, cools it down again and never restarts. Any thoughts? Main board perhaps??

    • if evaporator fan in fridge compartment working ok, but still not cooling, then there is ice build-up behind Twin Cooling Panel, restricting airflow in the fridge. Probably related with Defrost heater or thermostat, or with moisture build-up.

    • Hi Noli, you need to remove the back panel in the freezer and check for continuity: 1. Defrost Thermal Fuse 2.Heater . If you will notice a lot of frost or ice build up on the evaporator coils behind that panel, then most likely an issue with one of the parts mentioned before. That frost blocking air circulation in the freezer.

  15. Hello,
    I have a Samsung RB196ACRS, the refrigerator’s fan has started to make noise, I have seen on the refrigerator compartment back panel some frost from vent holes. I have run three « rd » for removing fan noise. Now the refrigerator does not cool to the set point and stay at 50 F? I disconnect and reconnect the AC power supply without success, I have unplugged it for 5 minutes. Thanks for your help!

    Reply
    • Hi Eric, you need to let it completely defrost first. Then you need to remove back panel where it says Twin Cooling. After that check if you have standing water at the bottom. If you have, then check drain line grommets (most likely they are clogged) on the back of the fridge. In other words, if you have standing water where the cooling coils are, condensation will go up and eventually become ice and will block the evaporator fan.

      Reply
      • Hi Eugene, I really appreciate your rapid help. I understand your point but I do not understand why the temperature stuck at 50 F and does not move. My hypothesis was the demo mode but I try the demo mode and exit of it without success, I unplugged and plugged the refrigerator again. The freezer work great and the refrigerator compartment does not have water and over frost. I have checked for the self test with the user’s panel so no error? 6 years ago a technician un warranty but a bigger heat element in the drain hole because I had water in the refrigerator compartment and the drain hole was freezed. Thanks!

  16. Hello,

    I have a samsung refrigerator model number RF26HFENDSR. I was getting frost build up towards the back of the refrigerator where the twin cooling panel is towards in the middle. I have defrosted it before and the frost build up keeps happening. Today I noticed that the fridge is not cooling anymore and the temperature keeps flashing. The freezer seems to still be working. is there anything i can do to fix it or do i need to call a technician?
    Thank you.

    • Hi Al, you need to check if you have standing water in the drain hole behind that panel where is says Twin Cooling. Standing water evaporates and accumulates on the top and then becomes ice and blocking evaporator fan. Then check drain grommets behind the fridge. if they are clogged replace them.

  17. Hello,

    I have a SAMSUNG model RFG297AARS (french door fridge, bottom drawer freezer). The problem we seem to be having is in the freezer. The freezer has an “auto pull out drawer” on the top that does not seem to be freezing anything. The lower half of the freezer is fine, and the temp of the freezer is reading as -21 degrees, but nothing on that top shelf seems to be freezing. Any ideas as to where to start?

    Thanks.

  18. Hi,
    I have a Samsung RF26HFENDSR, the fridge portion says 3 degrees cel but it’s still warm inside .
    The freezer works well
    There is some ice build up in the holes on the Twin cooling panel .
    What do I do ?
    I’ve read some previous comments so you may have answered this already .
    If I have to defrost ( if that’s the solution) , can I do so without affecting the freezer ?
    Thank you

    • Hi Vash, you need to defrost it completely, then remove that panel “Twin Cooling” and see if any ice left in the drain hole. If some left, you have a problem with drainage and some condensation build up because of that and eventually become ice. You need to change these parts

  19. Hi,
    I have a Samsung model RL39TRCMG (RL39TRCMG1/XEF 01) refrigerator that stopped working properly: the fridge is warm (around 16 degrees C) while the freezer is working perfectly. The compressor seems fine and the fridge sounds like it’s working properly. I am in quarantine so calling a repairman isn’t an option – any ideas on what could be wrong? I have tried power cycling it for 10 minutes but I have not done a full defrost yet. Thanks in advance for any assistance!!

    • If the fridge not colling properly, so maybe you have an issue with ice build up behind the panel where it says Twin Cooling, blocking airflow in the fridge and thus not cooling.

  24. Hi Eugene. I have a Samsung twin cooling ref. My mother once cleaned the ref and when she plugs it back we noticed the freezer is not working. I put it to a service center and they charged me around 150 dollars for vaccuming and putting freons as they claimed. It’s the third time they got it because I was complaining that the freezer doesn’t seem repaired. They say it could be power supply coming from my plug? I was wondering because that has been the plug since I got it. I’m confused. Please enlighten me.

    • Hello, if it was sealed system issue and lack of freon, both freezer and fridge compartment will not stay cold, because they are supplying from the same source. Hard to say what happened in your case though

  31. Hi. I have a 6yr old samsung french door refrigerator. I’m encountering problems lately. 1st it was ice build-up on the refrigerator above the twin-cooling wall. I defrost the ref and went okay. Then, after sometime I heard a loud sound like a fun running but everytime I open the refrigerator it will stop. Then I pressed the freezer and lighting panel to fix the problem. It worked for a little bit then the fun went loud again and finally stopped. But when it stopped, I noticed that the refrigerator is not cooling enough. I pull out the plug to defrost it for 12 hrs. When I plug it back today, I set it to -2 for freezer and 38 for refrigerator. But it seems like the I’m not getting enough cold for both freezer and refrigerator. Can you please help me?

    As much as possible I don’t want to call service man bec of the corona virus. I hope you can help me figure out what’s going on. Thank you!

    • The noise or loud sound you heard, was coming from evaporator fan which partially blocked by ice. When this fan is stopped, air will not circulate inside the fridge and the temp will go up. You need to turn fridge OFF for 24 hours and let it thaw. Then you need to pull the fridge out and change drain tube behind the fridge (see post above). By changing these tubes, It should help to drain properly and not to collect condensation in the fridge

  32. I have a samsung model rfg298aabp that stopped cooling the fridge and freezer both. I replaced the compressor overload protector but it didn’t make a difference. The compressor checks out fine. What else can be the problem. The compressor fan works fine also.
