5 Reasons Why Samsung Fridge Not Cooling

If you searching for the answer “Why my Samsung fridge is not cooling?”. Well, there are several reasons for that.

Samsung fridges “notorious” to have problems starts with Twin Cooling Plus technology, evaporator fan failure and ended up compressor failure.

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?

    • 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?

      Reply
      • 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)

    • 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??

    • 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!

          • Last thing left, it is back panel where it says twin cooling. Maybe styrofoam broke and letting warm air get in. IDK… To be honest, dealing with Samsung fridges always tricky, never know if it will help or not and just keep trying ))) Even Samsung don’t have a proper solution in many cases, just sending their tech over and over

  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.

  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

      • My Samsung is not cooling or freezing. Twin cool fan works, the fan by the compressor works, I can hear the compressor come on, no frost build up or clogged drains, and no codes. Did this about 2 months ago, I took it all apart, checked behind the twin cooling panel, and only found a clogged drain tube. Cleaned it, put it all back together, and it worked fine until a couple of days ago.

  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

  34. Hi Mr. Smith,

    I have a seven year old Samsung french door refrigerator, model RF263TEAEBC. The freezer works perfect. The fridge is 10 deg higher than the temperature reads when I press the control panel. I have done a quick cool and the temp read says it is 26 deg but the actual is 36. That is as cold as I can get it. When quick cool is off, it will settle at an actual of 44 and the display says 34.

    I have changed the temp sensor inside the fridge. Nothing changed. I have no frost issues on the evaporator. I have placed a magnet on the door sensor and verified the fan is working.

    All the seals look good. Any ideas what it might be or what I should check next?

    Thank you in advance,

      • Hi Eugene,

        I have a glass of water inside and I use a digital thermometer. I probably should put more than one glass. Good point. I should set up in a few different locations. I bought something on Amazon that has two separate sensors that I can monitor without having to open the door. I hope that works better.

      • Eugene,

        I bought a set of wireless thermometers that I can read from the outside of the fridge. I put one on the back of the bottom shelf and one on the front of the top shelf. I figured I would put one as close to the source as possible and one as far from the source as possible. The temp is set on the front panel at 34.

        I have been logging the temps since this morning. When it was 42.3/40.8, it was opened for 30 sec. It went up to 44.8/41.7. I did a quick cool until it reached 36.9 / 32.2.

        It was not opened for 2.5 hours. At that point it was 39.4/38.3. It was opened for an extended time to put some items in and it climbed to 48.4/43.

        30 min later it is at 48.4 / 42.6. That’s where I’m at. I don’t know what it could be.

        Thank you again,

        • Don’t know Mike why fridge temp is fluctuating that much. But, what if you will check if any frost behind the back panel? It may partially block air circulation in the fridge. Or you can turn fridge off for 24 hours with the door open and then turn ON to see if will start maintaining proper temp.

          • Eugene,

            I’ve checked for frost behind the back panel. There was none. I’ve ordered a new main board. It’s worth a shot before I drop 2k on another refrigerator. I’ll let you know how it goes.

            Thank you,

            Mike

          • I’m having the same exact issue as Mike. I’ve replaced the thermosister and evaporator fan. Defrost is working right but temperature is swinging 15 degrees or more throughout the day.

  35. Hello. I have light brown water collecting in the right hand vegetable drawer of my Samsung French door bottom freezer unit. I recently had to reset the fridge bc the freezer was not getting below 4 degrees. That seems to be fine now. Please advise. Thank you for your help. Am happy to compensate you for your time.

  36. Eugene,

    I think I have read the off for 24 hours before. Is there anything in the brains of these things that will reset after that much time?

    Thank you,

  37. I defrosted my Samsung RF4287HARS/xaa01 for 8 hours and cleared the drain tube and evaporator fan using a hairdryer. It is definitely improved, but frig is not getting down as cool as it should (39-42instead of 35-38). Any suggestions? I am wondering if I did not complete the defrost and airflow is still restricted somewhere I cannot see.

  38. Hi, Eugene:

    I have a Samsung RFG297AARS. Both Fridge and Freezer not working. If I unplug the power a few minutes, then power on. It will start cooling and freezing. But it only last a couple days. then it needs unplug again. Could you help me to figure it out what the potential problem are? I have spent a couple hundred dollars on it but the technician can’t fix the issue.

    Thank you very much for your help.

    • Its not an easy one, you need to monitor compressor how often it turns on and off. Can you confirm that, when it stop cooling compressor still running? If yes, then probably compressor failing or there is an issue with sealed system

  39. I have a French door fridge with the middle drawer. Lately a lot of water and some ice has been building up in the lefthand holes of the twin cooling panel. It then started making a very loud noise when the fan was running. It did shut off when I opened the door. Also the middle drawer which is set for 1c is freezing the cans of pop at the back. Last night my husband unplugged the fridge out of frustration overnight. Now nothing is cooling and the fan isn’t starting up again…very quiet. Also a lot of water collects under the middle drawer and freezes…not sure if this issue is related to the noise and fan. Any help here would be grateful.

  40. Hi

    I have a Samsung refrigerator model RB1855SL. I programmed it at 3 degres but is keep swinging between 9 and 3 degres all the time, keeping all my food at a mild temperature. What do you think is the cause of this ?

  41. We have Samsung side-by-side RS2534WW. The freezer side works perfectly. We have Fridge temperature set at 36 F. The LED display for the fridge keeps fluctuating temperature readings between 42 and 59. A thermometer inside the Fridge displays between 41 and 48. The drain tubes on the back are completely clean – no blockage.

  42. I have an RFG237AARS and the freezer has started intermittently being warmer than it should be. I verified the door seal is good, no ice buildup on either fridge or freezer evap. Both fans in freezer work. Verified ohm reading on freezer ceiling mounted thermostat. It will freeze properly in FF3 mode. No codes on the inverter board or front panel. I initially thought the defrost heater was getting stuck on but I removed the power to it and the freezer still fluctuates from 10-30°F with it set on -8. Could this be a start relay issue? Fridge appears to be working just fine.

  43. I have a Samsung RF263BEAESR about 6-7 years old. Icemaker is frozen over, ice build up in the fridge on the back, water leaking into all of the veggie, and deli drawers, and temp is about 10-15 degrees higher (tested water that was in a pitcher) than the display.

    Mine is samsung RF28HMEDBSR french door one. Noticed that fridge is not cool enough even though the panel says 2 degrees celsius. I have checked the milk and it was 15 degrees celcius. It had ice build up, I could see ice from both holes on twin cooling panel. I have unplugged the fridge for 9 hours then plugged back. Now it won’t cool the fridge part, the freezer is working fine. The temperature on panel is 14 degrees after 10 hrs of power on. Any advice? Thanks in advance.

    • If you just want to temporarily fix it, then turn the fridge off for at least 24 hours with the doors open and let it thaw. After that, temp should back to normal. In order to TRY to fix it permanently then it requires changing drain tubes or changing back panel (Twin Cooling) or changing defrost sensor. Unfortunately, there is no one solution for everyone.

  45. I also have a Samsung French door fridge:

    Replaced all 3 sensors in/ around the Twin Cooling cover after having ice buildup as most of these seem to do. Cleaned drain and added the aluminum heating element extender down into the drain tube. Fan runs fine as best I can tell and turns on when I use the magnet trick to make it think the doors are closed.

    Freezer temp matches display but fridge is 50* when display is set to 34*. Tested multiple areas inside fridge space. No ice on evaporator after sensor replacement.

    What am I missing or what else should I try?

    Thank you!

  46. I’m having a similar problem, refrigerator was warm but freezer and middle drawer were cooling fine. Found the fan was frozen and defrosted it. Worked great for 2 days, now it freezes up and I have to take it apart to defrost every 2 days. Another strange component is that the thermostat on the outside of the fridge reads 34 even when the temp inside is obviously close to 50. Is there any chance they two pieces point to a specific faulty component I can replace? The model number is RF28HMEDBSR.

          • On the back of the fridge there is the water inlet hose for the ice maker, then an blue & gray tube coming from the center back of the fridge that go up to the right top corner. We took the black cover off where the hoses go into the center of the fridge and the hoses are all covered in what looks like a soft expanding insulation. In order to remove them and check the inside we would need to break the insulation. Are these the lines you are referring to?

  47. I have a Samsung model RFG298AABP. The whole fridge does not have power. I have tested the power outlet and it is working fine but the fridge just randomly stopped working. I had breakfast and took a few things out, and put them back in, and right as I put away the last bit of food, the light went out. I thought that I needed to fix the light but then I realized the whole fridge is without power.

    • If both freezer and fridge not cooling, check compressor to make sure it’s running. If it’s running and not producing cold, then its a major problem with your fridge, related either with a compressor or sealed system

  49. Hi Eugene, I recently moved. My Samsung Twin Cooling RB195ACBP fridge was in storage for 3 months and was working perfectly fine for 2 years before this. Previously in that time it had 2 problems, water would accumulate in my drawers and it would make a slight grinding noise when opening the fridge. When I finally turned it back on after the move. It seemed like it was working fine and my bottom freezer was super cold -2. Two weeks later, my top fridge stopped cooling completeIy. It goes from 40f to 55f now. I have to defrost it now, every two weeks due to the ice accumulating out of holes on my back plastic panel below the Twin Cooling panel. Yet, my freezer still gets cold. What exactly could be wrong? I havent been able to check in the back for the coils or the fan. But, I am asuming it is the fan. It would go from getting cold, keeping temp after it was defrosted/unplugged to getting frozen and not getting warm in the fridge every two weeks. Or should all three parts you mentioned be replaced?

  50. I’m super hoping you get this: we had a random power outage; no storm. It caused our hot water heater AND refrigerator to go out. Called a repair man for the fridge. He said it needed a new switch board and was going to charge us a ridiculous amount of money. So we bought a new control panel and installed it. But nothing is happening. He was certain this was the problem. Any tips?? We know it can’t be the frost issue as it’s been 100 degree days and 80 in our home so there is no chance of frost anywhere after 3 days not working. HELP!

  51. Hi. I have a RSH model Samsung that I just got second hand.

    Everything turns on and I can see the temperature which is stuck at 18 Celsius. None of the fridge freezer power freeze buttons do anything.

    Although the buttons do work to hard reset and turn child lock on and off. This means my appliance isn’t getting cold as it’s staying at 18 degrees.

    Any ideas?

  54. hi, thanks for your amazingly informative blog. I just purchased a samsung RF220nctaww fridge from a nice family who had the fridge originally. When I started up the fridge the freezer works alright, but the fridge didn’t build up cold, the fan is running okay after I put the fridge in demo mode and back to normal as the manual directed. the fridge was unplugged for few hours during the transport and I am assuming that any ice build up should have been melted during the transport.
    Any suggestions for this smaller model? are there any hecks and tricks that you could teach me please? I have no idea what other panel reset sequences are there, but I really suspect there must be a thermostat or temperature sensor are out of wack.
    please help, thanks

  55. Hello, I have Samsung Fridge/Freezer model RF30HBEDBSR. Power 115V/60 Hz. a few weeks ago the freezer stopped freezing. We replaced the entire unit and put this one in the garage. For several weeks the Fridge was still cooling, but gradually less cool. For a while we had a “E 40” flashing on LED panel. Then about a week ago the fridge stopped cooling, and the E stopped flashing. I’ve had it turned off for a couple of days at a time, but it never comes back to cooling. I’d like to try to fix it and buy needed parts, but want to make sure I get the right parts. How can I trouble shoot to identify the defective parts?

  56. Hi Eugene,
    I have 10 year old Samsung RF268ABRS, French door refrigerator/freezer. The refrigerator fan is not working. There is no power going to the fan plug. I attached the fan to 12V car battery and it worked. Looking at main control boards and even though they are suppose to match, I find slight differences. Not sure if needs main control board but cannot think of anything else?
    Originally, the freezer stopped cooling and the refrigerator worked fine. I shut the fridge down and it thawed. Turned it back on, freezer fine, but refrigerator stopped cooling properly. It was froze over on the coils. Thawed it down and fan not getting power at plug. All else seems fine but fridge fan.

  57. Need some advise. I have a Samsung french door Model RS2555SL. No trouble until today. Freezer and Refrigerator are not cooling. Compressors do not seem to be coming on. Audible fan running is detected. Control panel showed -10F Freezer and 34F Fridge. I shut off the breaker, waited 1 minute, turned the breaker back on. Control panel now reads 41F Freezer and 55F Fridge. About every 3 minutes I hear a “click” like something is attempting to turn on. Any suggestions on how to trouble shoot?

    Reply
    • Check start relay on the compressor. If its clicks every 1-2 minutes, its trying to start compressor, but for some reason not able to. If it clicks only ONCE and then silent, its not start relay. Its some of the relays on the control board. But anyways, check start relay first and if its needed replace it

      Reply
        • Feedback – The compressor relay was replaced and the refrigerator is running. Refrigerator reached set temp of 36F without any issue. On the other hand, the freezer has issues. I noticed the evaporator fan was not coming on and decided to order a new one. The freezer is reading 77F on the controller; however, actual inside temp measures ~30F. Defrost Thermostat issue?

          Reply
        • Update. Controller still showing 77F. Freezer actual temp is continuing to fall, now at 25F. So freezer is working, but controller is to registering the correct temp.

A good handyman myself but cannot figure out how to remove the twin cooling panel without breaking it.

How about a video on removing the twin cooling panel. Any suggestions.

  61. I have a Samsung RF267AA refrigerator and the freezer is not reaching the desired temperature. I have checked and no ice buildup on the coils. The panel says -2 (or whatever it is set for) but the actual temperature is much warmer. I have replaced both temp sensors in the freezer section and the bimetal defrost sensor. Still doesn’t work.
    What I have noticed is that if I unplug the refrigerator and plug back in, it will show the correct (warm) temperature and will start cooling. But after a while, it will show -2 again even though the actual temperature is much warmer.
    Ideas?

    • Hard to say what exactly happened with you fridge. AS long as the fridge doesn’t have ice build-up, then it can be: 1. leak in the sealed system or compressor lost efficiency 2. Faulty control board

  62. Thanks.
    In case of 1 above, I guess you toss the refrigerator?
    In case of 2 above, there is a main control board and a power module board. Which do you think it is? (The power module doesn’t seem to be in production anymore).

  65. Hi Eugene,

    My refrigerator model number Samsung RFG237AARS stopped cooling all together. Both compartments (refrigerator and freezer) are warm. I already checked the condenser + fan both are running.
    Also removed the inside panel and checked the evaporator fan by tricking the refrigerator with the magnets, comes on after 15-30 sec. Attempted to run self-diagnostic by holding Energy Saver+Lighting buttons. The LCD display resets and shows 88 88, then goes back to normal mode. Don’t see any error codes to help me troubleshoot the cause. Any pointers would be greatly appreciated! Thanks in advance.

  66. My Side by Side Twin cooling model has the same issue..Freezer works. Fridge evaporator coil icing up and fan not running. So not cooling the way it supposed to.
    I replaced the following:
    Evaporator Fan, Defrost heater, thermistor, control board. Replaced the metal plate under the defrost coil. Still fan not running. Icing up continues. Tired of it. Unplugged the fan wire and checked for power. No power to the socket from control board even after replacing the board. Why it is? Do fan works only when the thermistor sends signal to board? Is that the reason for not cooling? Anyone has any idea?

I was able to defrost overnight and see that the ice was built up in the drain area so I’m assuming that’s the cause for my issues (fridge not getting to temp) but I don’t know how to get to the drain part to change it out.

  70. Eugene thanks for answering all these questions, that’s a lot of effort and should be commended.

    My temperature was blinking and I unplugged and wouldn’t go down. So I removed the twin cooling system panel and ice froze the fan and top right part of the inside. I thawed and got the ice off. I then tried to move the fan manually and it felt stuck and wouldn’t turn freely. I did some adjustments to the part to get it to move freely like putting the screw back on the container of the fan but not clicking it back in place as if there was an issue with the placement of the electronic fan part inside the protective part. I turned on and let sit and opened fridge a little later and it was working. I put panel back on. The temperature is going down but slowly on power cool. I just can’t get it in the thirties. Do you think it’s the fan? What caused that ice build up? I put in new grommet a while back to heat bottom part inside panel which was recommended.

    • Does the compressor is running? Can you hear it? if not, then turn the power off or unplug it, remove back panel on the left side where control board is. Reconnect connectors connected to the inverter board (bottom one) or even clean them with contact cleaner and connect them back. I’ve seen this issue before and after reconnecting, compressor kicked ON right away. Regarding OF, means fridge in DEMO mode. Push freezer and fridge buttons at the same time, to exit DEMO mode and turn fridge ON
