Top Fixes for Samsung Fridge Not Cooling

A Samsung fridge will typically cool without any issues, however, there are a few minor things that can cause a Samsung fridge to not cool that are easily fixed. Today, I will explain the top fixes for a Samsung fridge not cooling.

In general, the vents are blocked, the door doesn’t close properly, it’s too close to the wall behind it or a heat source, it’s not getting power, cooling mode is turned off, the temperature is set too low, the condenser coil needs cleaning, or an internal component has failed.

Each of these issues that can cause a Samsung fridge to not cool can be fixed by yourself in most cases. Below, I will cover each of them, how to inspect for each of these issues that can cause a Samsung fridge to not cool, and how to fix each of these issues.

Samsung Fridge Is Not Cooling Because Vents are Blocked

A common reason that a Samsung fridge won’t cool is that the cool air vents are blocked. They are reasonably small and located in places that make them difficult to see, so it’s easy to cover them accidentally. Therefore, this is where and what to check and do to ensure the vents on your Samsung fridge aren’t blocked.

In general, there are multiple vents located on the sides, top, bottom, and back of a Samsung fridge, as well as, in the freezer. If any of these are blocked it will stop cool air from entering your fridge. Check all the vents aren’t covered with a food or drink item.

All fridges including Samsung fridges have a fan, which is typically located at the rear of the fridge. It sucks cool air from the freezer and blows it every now and then into the fridge. If your Samsung fridge does not have a freezer then it will blow air into the vents in your fridge from the cooling element on your fridge.

Samsung Refrigerator Won’t Cool Because Door Doesn’t Close Properly

For a Samsung refrigerator to cool properly the door needs to be closed, and the seals around the door need to be completely airtight. It’s common for the seals on a fridge to be damaged, or for something else to be an issue that causes the door to not close properly. Here is how to inspect the door on your Samsung fridge to make sure that it’s completely closed, and creating an airtight seal.

As a general rule, visually inspect the seals around the door and where the door meets your Samsung fridge. It should close completely without any gaps for air to get in and out of the fridge. If the seals are dirty or damaged they need to be repaired.

It’s possible some food or drink was spilled in the fridge, and some grime has accumulated on the seals. As a result, they don’t seal properly. If they are a bit dirty they can be cleaned with warm soapy water.

In other cases there can be an item of food or packaging that is getting stuck in the door hinge or exterior of the fridge. When this happens the don’t won’t close completely.

Inspect the door of your fridge when you close it to ensure it’s completely closed. If it doesn’t close all the way then look for things that are stuck in the door hinge or stopping the door from closing.

Samsung Refrigerator Won’t Cool Because It’s Too Close to the Wall Behind it

There are a few components at the rear of a Samsung fridge. If the fridge is positioned so that the back of the fridge is too close to the wall it’s against, it will affect your fridge’s performance. This is how to check if the issue that is causing your Samsung fridge to not cool.

In general, leave a minimum of 1 inch (2.5 cm) between the back of the fridge, and the wall behind it. Doing so will allow enough air flow over the components at the rear of the fridge, and stop them from overheating.

This step is very straight forward, take a look at the rear of your fridge, and take a tape measure and ensure the back of your Samsung fridge is at least 1 inch (2.5 cm) from the rear wall. And walk it forward if it’s not. Then wait about 12 hours and see if your Samsung fridge is now cooling.

Samsung Refrigerator Won’t Cool Because It’s Not Getting Power

As simple as it sounds, a Samsung fridge needs electricity from the wall outlet to operate. It’s common that there is a minor issue with the wall outlet, therefore, you should double check that your Samsung fridge is getting power using the steps below.

Overall, first check it’s plugged in all the way at the wall outlet. Then take another appliance, or device and plug it into the same wall outlet your Samsung fridge is plugged into. If another device works on the same wall outlet then you can be sure the wall outlet is working.

When the wall outlet is not supplying power it’s typically because the fuse at the switchboard for your home has been tripped. Go to the switch board for your house and see if the fuse to the part of your house where you fridge is has triggered due to a power surge. And turn it back into the on position if it has.

Then verify the wall outlet your Samsung fridge is plugged into is supplying power again. Provided it does, plug your Samsung fridge back in, and wait about 24 hours for your fridge to cool completely.

Samsung Refrigerator Won’t Cool Because Cooling is Turned Off

On many fridges such as Samsung refrigerators there is what is called cooling mode, which is also called demo mode. This is a mode where everything on the refrigerator works except it doesn’t cool, and is designed to be used when fridges are on display in a store. It’s possible the reason your Samsung fridge is not cooling is because it’s in demo mode, so here is how to take it in and out of demo mode.

As a general rule, you hold the left and right arrow at the bottom of the control panel. But, if you have a Samsung fridge with a full touch screen then go to the cooling mode setting and turn it off. Each model and year of Samsung fridge is slightly different, so refer to your owners manual.

Some fridges also have Sabbath mode. This mode disables your fridge on the Sabbath which is a Saturday. This could be enabled and needs to be disabled.

In short the settings you want to disable are:

  • Cooling mode
  • Demo mode
  • Sabbath mode

You can find an online version of the owners manual for your specific Samsung fridge on this page of the official Samsung website. Read the instructions there to make sure these modes are disabled.

Samsung Refrigerator Won’t Cool Because Your Fridge Is Next To a Heat Source

A refrigerator works by cooling air it draws in from the room where it’s located. Therefore, if the room or area where it is, is too hot it will cause your Samsung fridge to struggle to stay cool. Here are instructions for where to place a Samsung refrigerator to make sure your fridge doesn’t get too hot.

In general, ensure your Samsung fridge is at least 2 feet (60 cm) from a heat source such as a countertop. Also, don’t locate your fridge where it’s not located in direct sunlight, and in a room that doesn’t get too hot. Commonly garages will be too hot on sunny days.

A garage door typically gets full sun for part of the day and will heat up a lot. This raises the temperature in the garage quite high, and a Samsung fridge can’t function normally. Ideally, a fridge should be out of direct sunlight and a decent distance from a countertop.

Samsung Refrigerator Won’t Cool Because The Temperature Is Set Too Warm

There is a temperature dial on Samsung fridges. Some have digital controls, while others have a knob that you turn up and down. It’s possible it was set too warm by accident, or the temperature knob has been turned accidentally, so here is how to change the temperature and what the temperature should be set to.

As a general rule, 40°F (4.4°C) or below is what a Samsung fridge should be set to. On most models with a digital display you press the button that says fridge twice, and then when you press it again, it will cycle to decrease the temperature by 1 degree. For models with a knob, do the steps below.

Put the knob on the middle setting. Rather than on the coldest or warmest setting you can turn the knob to. If these instructions for a fridge with a digital display, or a manual knob don’t work, then refer to the instructions in the owner’s manual for your specific fridge make and model.

Also, in case you need to change the freezer setting as well. It should be set to 28.4°F (-2°C). Keeping in mind water freezes at 30°F (0°C).

If you have a fridge with a digital display there is a child lock. This can prevent children from changing the settings once you’ve set them.

Samsung Refrigerator Won’t Cool Because It’s a New Install

It’s somewhat common for people to defrost a fridge to clean it, when this happens it takes quite some time for a fridge to cool itself. This is also the case if your Samsung fridge is brand new, or you just plugged it in for the first time so here is how long it takes for a fridge to be cool.

In general, it will take 24 hours for a Samsung fridge to be cold inside when it is first installed. Or, if it has been turned off for a long enough period of time for the fridge to return to room temperature.

If your fridge has been turned on for 24 hours, and the interior is still not cool, then there’s another issue. Move on the next reason why your Samsung fridge is not cool.

Samsung Refrigerator Won’t Cool Because The Condenser Coils Need Cleaning

All refrigerators have what are called condenser coils. This part of a fridge is responsible for cooling a fridge, but it’s common for them to accumulate dust. Condenser coils need good airflow to cool a fridge, so here is how to inspect and clean the condenser coils on your Samsung fridge.

Generally, there is a cover at the bottom of the back of your Samsung fridge that needs to be removed to expose the condenser coil. Remove any dust using a vacuum but be very gentle. The condenser coil metal is soft and bends easily. Below is a detailed video showing how to clean it.

As shown in the video, the condenser coils can also be blown out with an air compressor if you have one.

Samsung Refrigerator Won’t Cool Because An Internal Component Has Failed

While somewhat common, an internal component can fail. When this happens the component will need to be repaired or replaced. If you’ve tried all of the troubleshooting steps above, then here is what to do next.

In general, contact Samsung support to see if the repair or replacement is covered under warranty. They can also organize a repair technician if required. It’s possible to test and replace internal components yourself. But, requires experience working with tools, as well as a voltmeter.

It’s next to impossible to tell ahead of time what specific component is faulty. Each of the individual components need to be checked one by one using a voltmeter to see what the issue is. A voltmeter checks a component to see if it is allowing an electrical component through it. If it doesn’t then the component has failed.

But, first you should see if the repair is covered under warranty. Because it’s possible Samsung will replace your fridge. Or, cover the cost of the repair free of charge.

If it’s not covered under warranty, and you have some skills in working with tools, or on appliances then it can be a good idea to repair your fridge yourself. There are many good videos available online that show how to test each of the different components that make up a fridge.

Overall, it’s too close to the wall behind it or a heat source, cooling mode is turned off, the condenser coils need cleaning, an internal component has failed, the door can’t close properly, an internal component has failed, or one the vents are blocked.
