How To Fix Samsung Fridge Not Cooling

Hey Guys! Welcome to The Droid Guy. In this post, we are going to tackle why a Samsung fridge is not cooling properly, and how are we going to fix it.

Even the Samsung refrigerators you haven’t even tried yet will experience issues. But in comparison to other appliances, the problems you could run into when a Samsung refrigerator isn’t cold enough vary greatly.

A damaged evaporator fan motor is one of the most prevalent causes of a Samsung refrigerator not cooling. It is in charge of bringing cold air into the refrigerator’s evaporator coils, which are a vital component. If it doesn’t work, there won’t be enough cold air in the fridge to cool it.

If you have a Samsung refrigerator and it’s still not cooling properly, you should first check how much power is getting sent to the appliance from the outlet. Furthermore, you should check the ambient temperature because a hotter atmosphere makes a refrigerator work harder.

A few frequent causes of a Samsung refrigerator not cooling effectively are closeness to a wall, being in demo mode, having a broken door seal or faulty thermostat, or merely requiring to be reset.

Samsung Fridge Not Cooling


Start With The Basics

Samsung refrigerators have a history of cooling problems due to a number of typical problems. The first thing that you should do is  take the plug out for five minutes to try a quick reset.

The best approach to take when troubleshooting appliances is to start with the basics. Therefore, make sure your refrigerator is correctly connected in. To accomplish this, remove the plug from the socket and then firmly re-insert it. After completing this, you must inspect the socket itself.  You just need to  plug another appliance into the socket after unplugging the refrigerator to make sure the socket is functioning properly.

Check If The Refrigerator Is In Demo Mode

Your refrigerator may have been mistakenly left in demo mode if it is plugged in, switched on, and still not cooling. If a Samsung refrigerator from the Type A model is still in demo mode, the display will read “OF FF”.  If a Samsung refrigerator from the Type B model is still in demo mode, an icon will be lit up on the refrigerator’s display.

Look at the display panel on your refrigerator to turn off the demo mode. There are two buttons, one above the other, on the far left. One is labeled Power Freeze, and the other is labeled “Freezer” beneath it. The refrigerator will restart into normal operation if you press and hold both of these buttons for three seconds.

You can also review your user manual and check on how to disable the Demo mode.

Faulty Evaporator Fan Motor

As was already said, a broken evaporator fan motor is one of the most typical causes of a Samsung refrigerator not cooling. It draws chilly air into the refrigerator’s evaporator coils, which circulate it throughout. If it doesn’t work, there won’t be enough cold air inside the refrigerator to allow it to cool.

Here’s How To Fix It

Finding the evaporator fan motor will help you fix this. At the back of the freezer or refrigerator compartment, the evaporator fan motor is normally placed behind one or more panels. Try turning it manually once you’ve found it. You’ll need to replace out the fan motor if it’s impossible or too difficult to turn. The best course of action is to contact a repairman to help you identify the issue if it is simple to turn by hand but won’t move. The fan motor’s failure to operate could be caused by a problem with the windings or other connections.

Check The Fridge Door

Ensure that your fridge door is closed securely and firmly. If air is leaking out of the refrigerator, your fridge stops cooling. Assess the rubber or PVC gaskets and seals on your refrigerator’s door as well as the surface that closes. You need to replace them if they’re cracked, worn, or damaged because this could be the root of your cooling problem.

Air Damper Control

The air damper control is another reason in Samsung refrigerators that don’t cool. It’s a door that opens and closes on your refrigerator to permit cold air inside the compartment. It’s in charge of giving your refrigerator enough moving air to lower the temperature. Inspect the damper control. You might need to replace it if it’s jammed shut or doesn’t operate when you power on the refrigerator.

Faulty Temperature Control Board

Another component that may contribute to a Samsung refrigerator with cooling issues is the temperature control board, but repairing it takes the appropriate skills. Its job is to supply the compressor and evaporator fan motor with electrical power.

The temperature control board won’t be supplying voltage to the cooling system if it is malfunctioning. Check all of the most frequently faulty parts before you think about replacing the entire board. It can save you time and money because boards are readily misdiagnosed. If you have experience with electronics, you can either test the board yourself.

It is actually advisable to contact a repairman to handle this since a defective control board is an expensive component to replace. It’s also among the most frequently misdiagnosed problems with a refrigerator. Be sure to speak with a professional as soon as you suspect that the temperature control board in your refrigerator is broken.

Inspect The Temperature Settings

Verify whether you accidently pressed or bumped the refrigerator’s temperature setting, which would explain why it isn’t cooling down as it should. Check your controls or display, then re-adjust to the appropriate setting. For Samsung refrigerators, your fridge should be at ideal temperature, usually at or below 38 ° Fahrenheit, and your freezer should be at -2 degrees Fahrenheit.

Faulty Thermistor

The compressor and evaporator fan may not operate and the refrigerator won’t be cold enough if you have a faulty thermistor. Grab your reliable multi meter and check to see if it’s operating correctly. The thermistor resistance ought ideally alter in step with the temperature of the refrigerator. It should be replaced if the resistance isn’t shifting or the thermistor isn’t operating continuously.

Frosted Evaporator Coils

Even if your freezer is functioning, there are multiple causes why a Samsung refrigerator won’t cool. The evaporator coils being frosty is one of the most frequent causes, though. The defrost heater assembly and the evaporator coils are two components that are involved when this is a problem.

Throughout the day, the defrost heater assembly will activate multiple times. Its sole function is to melt the built-up frost on the evaporator coils. Ice will continue to accumulate without the defrost heater assembly, blocking the coils and reducing circulation across the coils. Even if the freezer is operating properly, a lack of airflow will prevent the refrigerator from cooling.

Check the evaporator coils to see if frost is present to determine if this is the cause of the problem you are having with your refrigerator. If so, start checking each component of your defrost system to identify which portion of the assembly is malfunctioning. The defrost system might be challenging to replace any component of. Because of this, it’s recommended that you only try to identify the problem’s root cause and let a maintenance specialist change the damaged component on your vehicle.

Faulty Condenser Fan Motor

Keep in mind  that the refrigerator should be disconnected first.  The refrigerator won’t cool properly if the condenser fan motor is blocked or damaged. Therefore, make sure the fan motor blades are not blocked because they won’t function properly if something is in the way of their ability to spin.

Once you’ve verified that, try manually spinning the blade. The condenser fan motor may need to be replaced if the blades don’t spin freely.

If there are no blockages and the fan blade spins easily when turned by hand, you can check the fan motor for continuity using a multimeter. Plug the refrigerator back in because it basically requires power at this point, but keep in mind to keep your hands away from the Motor Blades to avoid hurting yourself. It might be necessary to replace your fan motor if there isn’t electrical continuity. If you’re able to fix it by yourself, then that’s great. However it is best to get a professional repairman by contacting your local Samsung outlet or service center.

Faulty Start Relay

Another cause of the fridge’s cooling issues is a faulty start relay. The compressor may occasionally stop working or not work at all if the start relay is malfunctioning. As a result, the refrigerator won’t be cold enough. Using a multimeter, inspect for continuity between the run and start terminal sockets to determine whether the start relay is functioning properly. Replace the start relay if there is no continuity between the run and start terminal sockets.

Replace the start relay if it emits a burnt smell. It is no longer functional due to burnout.

Faulty Thermostat

The refrigerant system may not be able to run if your temperature control thermostat isn’t working. Try switching the thermostat from the lowest setting to the highest setting and listen for a “click” sound to see if it’s broken. It is presumably operating if the thermostat “clicks”. Test the thermostat for continuity with a multimeter if it doesn’t click. You must change it if there is no continuity in any configuration.

Faulty Start Capacitor

As soon as you turn on the compressor, the capacitor provides a power “surge.”  The compressor could not start if the capacitor is damaged. Test the start capacitor using a multimeter to ensure that it is functioning properly. It must be replaced if the reading lacks continuity.

Condenser Coils

On a Samsung fridge you’ll find the condenser coils either mounted on the back of the fridge OR recessed inside the cabinet at the back of the fridge at the bottom, they may be horizontal. If the condenser coils are grimy or dust covered, they won’t be working well, so you need to clean them.

Samsung recommends using your vacuum cleaner and a crevice tool to get into those tricky spots. When you’ve removed excess dust and vacuumed it up, go over the condenser coils with a damp cloth to thoroughly remove all debris.

Door Seals

Dirty seals are another factor in your refrigerator’s poor cooling performance. You should check your door seals to make sure they are not torn, weathered, or worn. The efficiency of cooling can be decreased by seals that have gaps that are big enough to permit warm air to enter.

If you notice dirty seals or any ice accumulation around the gasket, clean them up right away, and you should give your refrigerator up to 24 hours to reach its ideal working temperature.

Avoid Direct Sunlight & Heat

Make sure that your fridge is not hit by direct sunlight or any heat source. You can move your fridge or if you’re unable to move the refrigerator, you’ll need to reduce the freezer’s and the fridge’s temperature settings if the appliance has dual purposes. Keep in mind that you should adjust your fridge’s settings lower to maintain maximum cooling when the surrounding environment temperature is higher.

Keep Your Fridge Away From The Wall

Every Samsung refrigerator requires space around and behind it so that air can flow freely and cool components, like the condenser. If it is situated near the wall, it may not be cooling correctly. If your refrigerator isn’t cooling properly, consider pushing it further away from the wall. There should be at least one inch of space between the refrigerator and the wall.

That’s it. I hope we were able to help you one way or the other. Thanks for reading this post.
