Reasons Why Samsung Refrigerator Not Cooling and How To Fix It
1. Check the door.
If the door is not closed properly, the fridge will not be able to maintain a consistent temperature, and your food will not stay fresh for as long. Make sure that the door is completely closed every time you use it.
You should also check to see if there are any cracks or holes in the door seal. If there are, air can escape and cause the fridge to work harder to maintain a consistent temperature. To fix this, you can either replace the seal or use a door sealant.
2. In demo mode.
This mode is usually used in stores to display the refrigerator before it is sold.
To exit demo mode, press and hold the power save and lightning bolt buttons for three seconds. The control panel will beep and the display will return to normal operation.
3. Avoid sunlight.
The sun’s heat can cause the compressor to work harder than it needs to. If your refrigerator is in direct sunlight, try moving it to a different location.
Also, make sure that the air vents are not blocked. Blocked air vents can cause the refrigerator to overheat and stop working.
4. Overloaded.
Check if the refrigerator is overloaded and blocking air vents. An overstocked fridge can cause poor cooling. To fix this, remove some of the items from your fridge.
If your Samsung refrigerator is still not cooling, there are a few other things you can check. Make sure that the fridge is set to the correct temperature.
The optimal setting for a refrigerator is between 37 and 40 degrees Fahrenheit. If the fridge is set too low, it won’t cool properly. Conversely, if it’s set too high, the fridge will use more energy than necessary to maintain the cold temperature.
5. Condenser Coils.
These are the coils located on the back of your fridge, and they play a vital role in the cooling process.
If these coils are dirty, it can cause your fridge to work harder than it needs to, which can lead to premature failure.
Cleaning your condenser coils on a monthly basis is a good way to keep them operating at peak efficiency.
Why does it fail?
The most common reason for a refrigerator to stop cooling is that the condenser coils are dirty. The coils are located on the back of the fridge, and they help to release the heat that is generated by the fridge.
If the coils are covered in dust or dirt, they will not be able to release the heat properly, and the fridge will not be able to maintain a cool temperature.
Another reason for the coils to become dirty is if they are located near an air vent. The vents can blow dust and dirt onto the coils, which will eventually cause them to become clogged.
How to fix it?
The best way to clean the condenser coils is to use a vacuum cleaner with a brush attachment. You will need to remove the back panel of the fridge in order to access the coils.
Once you have removed the panel, simply use the brush attachment on the vacuum cleaner to remove any dust or dirt from the coils.
If you are having difficulty reaching the coils, you can also use a coil cleaning brush. These brushes are specifically designed to reach deep into the coils and remove any buildup.
After you have cleaned the coils, you should replace the back panel and plug the fridge back in. Once it is plugged in, turn on the fridge and let it run for a few hours to see if the problem has been fixed.
If the fridge is still not cooling properly, you may need to call a professional for further assistance.
6. Evaporator Coils are Frosted Over.
If your Samsung refrigerator is not cooling, one possible reason is that the evaporator coils are frosted over.
The defrost timer might be turned off, or set for too long a time interval. Check the instructions in your owner’s manual to see how to reset the defrost timer.
Why does it fail?
The fridge has to work harder to cool down. This causes the compressor to overheat and eventually fail.
What can you do about it?
If your fridge is starting to frost over, you should clean the coils. You can do this yourself by unplugging the fridge, removing the back panel, and using a brush or vacuum attachment to remove the dust and debris.
If you’re not comfortable doing this yourself, you can always call a professional. They’ll be able to clean the coils and get your fridge back up and running in no time!
7. Evaporator Fan Motor.
The evaporator fan motor draws air over the evaporator coils and through the refrigerator, cooling it. If your evaporator fan motor is not working, your fridge will not cool properly.
Why does it fail?
The main reason the evaporator fan motor fails is because of a build-up of ice and frost on the coils. This causes the motor to overheat and eventually burn out.
There are a few things you can do to prevent this from happening:
-Make sure your fridge is properly sealed so that cold air doesn’t escape.
-Clean the coils regularly to prevent a build-up of ice and frost.
-If you notice your fridge isn’t cooling properly, turn it off immediately and call a repairman.
8. Damper Control Assembly.
This is the part of the refrigerator that controls the airflow. If this assembly is not working properly, it could cause your refrigerator to not cool properly.
Why does it fail?
There are a few reasons why the Damper Control Assembly could fail.
The most common reason is that the assembly itself is dirty or damaged. Another possibility is that the fridge isn’t getting enough power, which can cause the damper to not open properly.
How to fix it?
If the problem is that the damper is dirty or damaged, you’ll need to replace it. However, if the problem is that the fridge isn’t getting enough power, you’ll need to check the wiring and make sure everything is properly connected.
Replacing the Damper Control Assembly is a pretty simple process. You can find the assembly at your local hardware store. Once you have the new assembly, just follow the instructions in your fridge’s manual to install it.
If you’re having trouble finding the right part or don’t feel comfortable replacing it yourself, you can always call a refrigerator repair service. They’ll be able to help you troubleshoot the problem and get your fridge back to working properly in no time.
9. Thermistor.
The thermistor is a key component in your Samsung refrigerator that helps to regulate the internal temperature.
If the thermistor is not working properly, it can cause the fridge to not cool properly. There are a few signs that you can look for to see if your thermistor may be going bad.
One sign is if you notice that your fridge is not cooling evenly. This means that some areas of the fridge may be warmer than others.
Another sign is if the fridge is taking longer than usual to cool down after you have added new food or drinks.
Why does it fail?
There are several reasons why a thermistor might fail. The most common reason is age and wear. Over time, the material in the thermistor can break down, causing it to become less accurate.
Another reason for failure is damage. This can happen if the refrigerator is dropped or banged around too much. If the fridge is exposed to extreme temperatures, the thermistor can also become damaged.
How to fix it?
If your thermistor is failing, you’ll need to replace it. This is a fairly simple repair that you can do yourself. First, disconnect the power to the fridge.
Then, remove the panel on the back of the fridge to access the thermistor.
Once you have located the thermistor, unplug it from its socket and plug in the new one. Replace the panel and turn the power back on. Your fridge should now be cooling properly.
If you’re not comfortable doing this repair yourself, you can always call a professional. Samsung offers a refrigerator repair service for its customers. You can schedule an appointment online or by calling customer service.
10. Start Relay.
If your refrigerator is not cooling, one of the first things to check is the start relay. The start relay is a small device that helps the compressor turn on.
If this relay is bad, the compressor will not turn on and your refrigerator will not cool.
Why does it fail?
The main reason the start relay fails is because of a bad capacitor. The capacitor is what provides the initial boost of electricity to get the compressor started. Once the compressor is running, the capacitor is no longer needed.
A failed capacitor will prevent the refrigerator from starting up correctly, and it will eventually cause the fridge to stop cooling altogether.
Other potential causes for a refrigerator not cooling include a failed compressor, low Freon levels, or a dirty condenser coil. But in most cases, it’s the start relay.
How to fix it?
If your refrigerator is not cooling, the first thing you should check is the start relay. A failed start relay is the most common reason for a fridge to stop cooling.
To check it, open up the back panel of your fridge and locate the compressor. The start relay will be mounted on or near the compressor.
Once you’ve found it, remove the two wires going to the start relay and use a multimeter to test for continuity. If there is no continuity, then the start relay needs to be replaced. You can find replacement relays online or at most hardware stores.
If your fridge is still not cooling after replacing the start relay, then you may have a more serious problem. Check the compressor and Freon levels next.
A failed compressor is much less common than a failed start relay, but it can still happen. And if your fridge is low on Freon, it will also cause the fridge to stop cooling.
11. Start Capacitor.
The start capacitor is located in the compressor of your Samsung refrigerator. If your fridge is not cooling, it may be because the start capacitor is damaged or has failed.
Why does it fail?
The most common reason for a start capacitor to fail is age and extended use. Over time, the capacitor will slowly lose its ability to hold a charge and will eventually need to be replaced. Other causes of failure can include damage from a power surge or voltage spike.
How to fix it?
If your start capacitor has failed, you will need to replace it with a new one. You can purchase a replacement capacitor at most hardware or home improvement stores. Be sure to take the old capacitor with you to ensure you get the correct size and voltage rating.
Once you have the new capacitor, simply remove the cover from the refrigerator and locate the old capacitor.
Disconnect the wires from the old capacitor and then remove it from the refrigerator. Install the new capacitor in the same location and reconnect the wires. Replace the cover on the refrigerator and you should be good to go!
12. Temperature Control Board.
This board controls the compressor and fans, and it may be defective if your fridge is not cooling properly.
You can test the temperature control board by using a multimeter to test for continuity. If there is no continuity, then you will need to replace the board.
Why does it fail?
The most common reason for the temperature control board to fail is because of a power surge. A power surge can damage the electronic components on the board and cause it to malfunction.
If you have a Samsung refrigerator that is not cooling, it is likely that the temperature control board is the problem.
How do you fix it?
If the temperature control board is the problem, you will need to replace it. You can purchase a replacement board from Samsung or from an authorized Samsung dealer.
Be sure to get the correct model number for your refrigerator so that you get the right board.
You can find the temperature control board inside the fridge, near the back. It will be a small, rectangular black box with wires coming out of it. You will need to remove the panel on the back of the fridge to access it. Be sure to unplug your fridge before you begin this repair.
Installing the new board is relatively easy. First, disconnect the power to your refrigerator. Next, remove the old board and replace it with the new one. Finally, reconnect the power and test your refrigerator to make sure that it is cooling properly.
13. Defrost Control Board.
This part controls the defrost cycle of the refrigerator and if it is not working properly, frost can build up on the evaporator coils.
If you suspect that this is the issue, check to see if there are any error codes displayed on the control board. If you see an error code, consult your owner’s manual to find out what it means.
Why does it fail?
The most common reason for the defrost control board to fail is because of a power surge. When there is a power outage, the defrost control board will reset itself. This can cause it to fail.
Another reason the defrost control board may fail is because of age. over time, the components on the board can degrade and stop working.
If the defrost control board fails, the refrigerator will not be able to properly defrost itself. This can cause the fridge to overheat and the food inside to spoil.
How to fix it?
If the defrost control board fails, it will need to be replaced. This is a relatively simple repair that can be done by a qualified technician.
14. Defrost Thermostat.
The defrost thermostat is located in the freezer compartment and controls the refrigerator temperature. If the defrost thermostat is not working, the refrigerator will not cool properly.
To test the defrost thermostat, remove it from the freezer compartment and place it in a cup of ice water. The thermostat should turn on and off at the correct temperature. If it does not, replace it with a new one.
You can find the defrost thermostat at your local hardware store or online. Be sure to get the correct model for your refrigerator.
Why does it fail?
The defrost thermostat is designed to shut off the flow of electricity to the compressor and fan motors when the refrigerator temperature gets too warm. However, over time, this component can fail due to normal wear and tear. When this happens, it can cause your fridge to stop cooling properly.
If you suspect that your defrost thermostat is failing, you’ll need to test it to be sure. The best way to do this is with a multimeter. Simply attach the probes to the thermostat’s terminals and check for continuity. If there is none, then the thermostat is likely faulty and will need to be replaced.
Fortunately, replacing a defrost thermostat is a relatively easy repair that you can do yourself. Just be sure to unplug your fridge before beginning any work on it. Then, remove the panel or cover from the back of the fridge to access the thermostat. Once you have located it, disconnect the wires and unscrew it from its mounting bracket.
16. Defrost Timer.
If your refrigerator has a defrost timer, it may be the reason why your fridge is not cooling. The timer controls the amount of time that the compressor runs. If the timer is not working properly, it can cause the compressor to run too much or too little.
To test if the defrost timer is working properly, you’ll need to locate it. The defrost timer is usually located in the refrigerator near the control panel. Once you’ve located it, turn it clockwise until you hear a click.
If the defrost timer is not working properly, it will need to be replaced. You can purchase a new one at your local hardware store or online.
If you’re not sure how to replace the defrost timer, we recommend hiring a professional. A professional will be able to properly diagnose the problem and make the necessary repairs.
17. Main Control Board.
The main control board is the heart of your fridge, so if it’s not working properly, it can cause your fridge to stop cooling. Luckily, this is an easy fix and you can do it yourself!
Simply order a new main control board from Samsung and follow the instructions in the owner’s manual to install it.
Why does it fail?
The main control board is the “brain” of your refrigerator. It regulates the temperature and tells the compressor when to run. If it fails, the entire fridge will stop working. The most common reason for failure is a power surge.
How do you fix it?
If your main control board has failed, you will need to replace it. You can do this yourself if you are handy with tools, or you can hire a professional. Either way, it is a fairly simple repair.
