Why Samsung Fridge Not Cooling? – Here are The Reasons

Samsung refrigerator is an expensive gadget that you expect to serve you for a long time. But sometimes electronics gadgets tend to disappoint and they don’t work as efficiently as expected.

At times, you’ll notice that your Samsung fridge is running as usual but not cooling food. So, if you’re asking why the Samsung fridge is not cooling, we have your answer here.

7 Reasons Why Is My Samsung Fridge Running but Not Cooling or Freezing?

1. Problems with the Evaporator Fan

When you notice that your Samsung fridge is not cooling, one of the culprits may be the fan. The refrigerator evaporator fan does the work of circulating cold air in the entire fridge unit. This, in turn, results in the cooling effect. Over time, the fan can have ice blockage, making it impossible for it to circulate normally.

To solve this problem, you should try turning the blade with your hand. If it turns free, then well and good. If it doesn’t, you have no option but to replace the evaporator fan motor.

If you have a French-door refrigerator, the solution to this problem can be pretty easy. All you have to do is close the left door and put a magnet on the right side. The magnet will stimulate the closure of the right door. Your fan will start running after a short while, thanks to the force from the magnet.

If your evaporator fan is defrosted, you need a different kind of solution for that. But it’s not as hard as it seems. Switching off your refrigerator and switching it back on after a few minutes can work.

2. Faulty Compressor

The compressor is like the backbone of your refrigerator cycle. This means a faulty one will mean the entire cooling process is in trouble. The compressor pushes high-pressure hot vapor from a cool, low-pressure vapor into the coils located outside the refrigerator.

This process creates some heat that forms warm gas. The warm gas then cools to absorb heat from the fridge resulting in the cooling effect.

So, if the fan is running correctly, but your fridge is not cooling, you should check the compressor start relay. The problem may be with the starter relay when the compressor itself is not destroyed.

You can only replace the start relay, which is cheaper than the compressor. If the problem persists after replacing the start relay, you might need to replace the entire compressor.

3. Thermostat Issues

The thermostat is tasked with monitoring the evaporator coil temperatures. It will initiate the defrost cycle whenever the thermostat temperature drops below normal. While this happens, the defrost thermostat heater will dissolve all the frost in the evaporator coils. But all this will only take place when your thermostat is in good condition.

With a faulty thermostat, the defrost process won’t take place. This means there will be no power flow hence no heating up the melted ice. The ice will build up in the evaporator coils.

You can test the thermostat using a multimeter to ensure continuity. When it reaches the low-temperature range and still your defrost thermostat doesn’t have continuity, it needs a replacement.

4. Dirty Condenser Coils

The condenser coils dissipate heat when cold refrigerant passes through them. When this happens, it cools the fridge. You can find the coil at the bottom of the fridge. Sometimes their location can be the cause of the accumulated dirt over time. What you need to know is that a dirty condenser coil will not function optimally.

The dirt may block the condenser coils interfering with its ability to cool the fridge. This is because the dirt will not allow for proper air circulation. So, if you’re asking why your Samsung fridge is not cooling, this might be the cause.

To solve this, you should check the condenser coil to find out if it’s dirty. Make sure you switch off your fridge and clean the condenser. You can use a coil brush to knock off the dust collected in the coils. You can then vacuum off the dust and plug it in your fridge to see if it’s back to its optimal function.

5. The Damper Control Assembly

The air damper in your Samsung fridge will open to let in cold air and close as soon as it gets enough. It’s generally the component that controls how much air enters the fridge from the freezer. But at times, the damper control fails to open correctly. When this happens, your refrigerator compartment won’t be receiving enough cold air. As a result, the fridge will not cool the food inside.

To solve this, check if the damper control is broken or stuck at the close. You can carefully remove the screws holding the damper cover to find it. When it’s broken or has other issues, you should consider installing a new air damper. You can also replace the other compartments you removed in the process and ensure everything is in perfect shape.

6. Clogged Condenser Fan

Your Samsung fridge will not cool if the condenser fan is clogged. The condenser fan motor is tasked with drawing air over the compressor through the condenser coils. When clogged, the fan may not spin freely, meaning no cool air circulation. If you have those models that come with a coil in the back, then forget about this problem as they don’t have the condenser fan.

You should solve this problem by cleaning the fan blades. After that, try spinning them with your hands to see if it spins freely. Plug back the fridge and see whether the situation changes. If it doesn’t, then you need to replace the condenser fan. If nothing is obstructing the fan, test the motor continuity with a multimeter. If there’s no continuity, replace it.

7.   Problems with the Main Control Board

The main control board of your Samsung fridge is the brain of the entire system. It controls all the major components, including the fan and the compressor. The control board failure means your fridge will not cool as required.

However, the main control board is rarely the culprit in why Samsung fridge not cooling. But, if all the above troubleshooting methods don’t work, you’re going to have to check it anyway. Start by testing all the components for defects. If you can’t find problems with all the common parts, you should consider replacing the main control board.

Conclusion

Not cooling or freezing issues is one of the problems Samsung fridge owners will experience. While sometimes this can be inconveniencing, most of the time, it’s not an issue to worry about. It can just be a malfunction of one of the components that you can easily fix yourself without calling an expert.

You’re assured that the Samsung fridge not cooling is not a permanent problem. You won’t need to dispose of it altogether. However, if all these simple fixes don’t work, attempting to work on it further may cause a much bigger problem. The best thing to do in such a situation is to get expert help. Don’t let the issue stress you out when help is just on your hands or just a phone call away.
