If your Samsung refrigerator is not cooling, you might be wondering what to do. Fortunately, there are a few simple steps you can follow to diagnose and fix the problem with your Samsung refrigerator without calling in a repairman.


Apart from being convenient, refrigerators also help keep food safe for long periods of time by keeping it cold and putting off bacteria growth through refrigeration.

When the refrigerator isn’t cooling properly, it won’t be able to keep food cold enough for long periods of time – potentially causing food poisoning and giving bacteria a chance to grow.

Therefore, if your Samsung fridge isn’t cooling properly, it means that bacteria growth is likely to occur more quickly than it should.

This article will show you how to fix your Samsung refrigerator if is not working properly and keep food fresh and safe for longer times by by providing enough cooling.

Why is my Samsung Refrigerator Not Cooling?

There are three main reasons why your Samsung refrigerator might not be cooling properly:

Power Outage or Insufficient Power Supply

If your home’s power supply is faulty or insufficient, this can cause the appliance to malfunction. In addition, if there was a power outage and the temperature was particularly hot previously, your Samsung fridge may still be warm.

Remember that most of the working parts of your Samsung refrigerator (the compressor, evaporator and condenser) need to be cooled down; otherwise, they overheat quickly and may cause permanent damage.

When this happens, you’ll notice that the freezer stops freezing or ice cream starts melting around the edges. This is due to the fact that the freezer is no longer cold enough to maintain its freezing temperature.

Refrigerator Defrosted or Water Stuck Inside

Another common reason why your Samsung refrigerator may not be cooling properly is that water has either entered the appliance or that it hasn’t been defrosted for a long time. This can happen if you don’t clean the coils of your refrigerator and, as a result, they build up enough ice to block the flow of air.

If this happens, open up a tray and see if there’s ice stuck to the coils. If you notice that there are chunks of ice stuck to the coils, it means that normal defrosting hasn’t taken place or your coil areas haven’t been cleaned for far too long.

More importantly, if your Samsung refrigerator isn’t cooling properly and there is a lot of ice built up, the evaporator may be leaking. If this should happen, you’ll notice that cool air is blowing out from some parts of your fridge.

If you’re not sure how to clean your appliance’s coils, refer to the user manual. If you don’t have the manual anymore or can’t find it online, try looking up your fridge model on the Samsung website using your fridge serial number.

Once you’ve found your refrigerator’s manual, follow the steps carefully and clean out excess water, but make sure to use a small brush to get into the little tubes.

The Compressor or Evaporator Coil Is Damaged

Your Samsung refrigerator will not cool normally if the appliance is too warm.

The reason why this happens could be that the evaporator or compressor is damaged. If you notice that your food isn’t cooling in the refrigerator, it’s likely that either one of these two parts aren’t functioning properly.

For instance, if your Samsung fridge is blowing warm air instead of cool air from its vents, it means that the evaporator may be damaged.

Methods to Fix Samsung Refrigerator When it is not Cooling

Some problems that can cause your Samsung refrigerator to stop cooling properly are fairly simple to fix yourself.

Let’s take a look at a few different ways you can go about fixing your Samsung refrigerator when it is not cold enough.

Method # 1: Use the Reset Button on the Back of the Fridge

If you turn off your Samsung refrigerator and then unplug the main power cable, it will reset many of its settings. However, this may not be a permanent fix for your problem.

To reset your Samsung refrigerator, follow the steps below:

  1. Turn off the Samsung refrigerator, remove its power cord and then again restore its power and turn it on.
  2. If that doesn’t help, unplug the Samsung fridge for an hour or so and plug it back in after a few hours.

Method # 2: Check to see if the Temperature is set Correctly

Before you turn your Samsung refrigerator off and on again (as described above), check to see how warm the thermostat has made the inside of the freezer.

If the temperature is set above 4 degrees Celsius, you will need to lower it so that the Samsung fridge doesn’t overheat and shut off on its own (as this could cause some serious issues). If your refrigerator has a manual thermostat setting, try having it at 0 or 1°C for best results.

Method # 3: Clean the Filter

The filter is a little bit of fabric with an opening underneath it to let the air flow through.

If the filter has some dust on it, it could be interfering with air flow and preventing cold air from getting into your refrigerator.

Method # 4: Check the Coils for Blockages

There are some grills or what look like vents in the front part of your fridge that allow air to flow into it, and most fridges have some coils on the back side to help with the cooling process.

A build up can sometimes occur within these coils and cause major problems for you refrigerator if they are not cleaned out regularly using a long screwdriver or something similar to remove dust and other blockages.


In conclusion, if your Samsung refrigerator is not cooling properly, this could be due to a number of different things.

It’s important that you troubleshoot these issues by following the steps above to see if they help with your problem. If just one or two things go wrong, it can cause serious issues for your fridge and parts of it will stop working properly.

However, if you notice that your Samsung fridge is not cooling or it’s producing warm air from its vents, don’t try to troubleshoot the problem on your own without calling a professional first.
