Is your food spoiling quicker than usual? Is the temperature inside the refrigerator consistently higher than normal? Are you seeing signs of moisture or even frost inside the refrigerator? These are signs the refrigerator fan is not running.
A Samsung fridge fan may stop working if there’s a buildup of ice that obstructs the fan blade movement. To fix this, unplug the refrigerator and remove the freezer’s contents and shelf to access the fan. Melt any accumulated ice with a hairdryer (on a low setting) or by leaving the unit off to defrost. Once defrosted, ensure the fan moves freely before turning the fridge back on.
If ice buildup is not the issue, the fan motor may be faulty. Over time, the motor can wear out or fail, preventing the fan from operating. To determine if the motor is the problem, you’ll need to test it with a multimeter after removing the panel that covers the fan. If the motor has continuity, it should be working correctly; if not, it needs replacing. Always ensure the fridge is unplugged before attempting any repairs to avoid electric shock.
With more of us working from home or attending school virtually, our kitchen appliances are getting more use these days. The most used appliance is our refrigerator. This article will help you troubleshoot why your Samsung refrigerator fan is not working so you can get back to your busy life.
Samsung Refrigerator Fan Not Running
The Samsung refrigerator is not a complicated machine but with many working parts, it can be difficult to troubleshoot problems. One of those crucial parts is the condenser fan.
If your Samsung refrigerator fan is not running, the condenser fan motor could be the culprit. The condenser fan motor is found behind the front grill at the bottom of the refrigerator. Remove the grill and clean any dirt and debris that has accumulated on the fan.
The condenser fan pulls air in through the condenser motor and then over the compressor. The fan keeps the air circulating so that warm air is continually removed from inside the refrigerator. This fan is essential to keeping the inside of the refrigerator cool.
The condenser fan motor is located behind the grill at the bottom of the outside of the refrigerator. Because it is at floor level, it very easily becomes clogged with dirt, hair, grease, and dust. This buildup of grime will prevent the fan from working.
To clean and inspect the condenser fan motor, unplug the refrigerator from its power source. Remove the grill covering the condenser. Clean the grill and the condenser with the brush attachment of the vacuum.
Inspect the fan for any broken blades or obstructions. Rotate the blades to make sure they are able to rotate freely and smoothly. If the blades do not move, the fan will need to be replaced.
Samsung Fridge Fan Noise/Buzzing
Normally the refrigerator works quietly in the kitchen without us even knowing it. If you are now hearing noises coming from the refrigerator, this means the refrigerator is in need of some attention.
The Samsung fridge fan noise/buzzing is an indicator that the fan is being obstructed or prevented from rotating. A defrost heating wire could be loose and is in the way of the fan. The fan blades could be hitting ice that has accumulated on the evaporator coils.
If your Samsung refrigerator is not defrosting properly, ice will begin to accumulate on the evaporator coils. These coils are located behind the panel in the back of the refrigerator. With nowhere to go, this buildup of ice will eventually block the fan from circulating air around the coils.
As the ice continues to build, you will hear loud buzzing noises coming from the fan. The easiest solution is to remove the ice build-up so the fan can rotate fully. The following steps will walk you through this process.
Step 1: Remove all perishable food from the refrigerator. Also, remove the shelves and crisper drawers.
Step 2: Press and hold both the Freezer and Lighting button until the display reads FD for forced defrost.
Step 3: Wait a couple of hours for the defrost cycle to run. The refrigerator will beep continuously through this process.
Step 4: After a couple of hours, turn off the defrost mode and unplug the refrigerator from its power source.
Step 5: Use a Phillips head screwdriver to remove the back panel inside the refrigerator.
Step 6: Once the panel is loose, disconnect the wire harness and then gently remove the panel.
Step 7: Use a hairdryer on the lowest setting to melt any remaining ice from off of the coils.
Step 8: Reconnect the panel and reinstall shelves and crisper drawers.
These steps will remove the ice buildup so the fan can now work. However, it does not solve the problem. A new heating wire will need to be installed in order to prevent the ice from accumulating again.
Samsung Fridge Fan Frozen
Are you playing hokey pokey with your refrigerator? Every couple of weeks are you taking everything out and putting everything back in your refrigerator? If the fridge fan is frozen you are.
The Samsung fridge fan is frozen if there is an accumulation of ice on the fan. This will happen if the seal around the evaporator coil is not tight. A loose seal will allow warm outside air into the refrigerator that is then frozen to the coil. Use weatherstripping or foil tape to seal any gaps.
If a bad evaporator coil seal is not the culprit, continue reading for more possibilities.
Food that is uncovered, especially liquids, releases a measure of moisture into the air. This moisture inside a refrigerator eventually freezes.
Samsung refrigerators have a built-in defrost cycle but it is a short cycle. A short defrost cycle coupled with increased moisture creates the perfect conditions for ice to accumulate on the fan.
Blocked Evaporator Hose And Drain
The evaporator hose and drain are located underneath the evaporator coil. As the heating wire heats up during the defrost cycle, any ice on the evaporator coils is melted. The water then runs down the hose and into the drain pan.
If the hose is blocked or frozen, water will remain in the drip tray underneath the evaporator coil and will refreeze. The ice will continue to accumulate and will eventually cover the evaporator coil, blocking the fan.
Loose Heating Clip
A small metal clip is connected to the heating wire and the drip tray. As the heating wire heats up, heat is transferred to the metal clip, which then heats up the drip tray. Any water in the tray is then run down the hose and into the drain pan, as discussed above.
If this metal clip is loose or is outside of the drip tray, heat is not transferred to the drip tray to melt any ice. The result is a buildup of ice.
Samsung Fridge Fan Runs Constantly
The refrigerator is always running. But the fan should not be running constantly. The purpose of the fan is to circulate warm air out and move cool air in.
If your Samsung fridge fan runs constantly, adjust the temperature setting inside the fridge to a higher setting. If the fridge is in a warm room or next to the stove, the added external heat will cause the fan to run constantly. Allow enough room on all sides of the fridge for air to circulate.
Here are some other possible reasons why the fridge fan runs constantly.
Defrost Timer And Thermostat
The defrost timer is a pre-programmed cycle to run every 8 to 10 hours. When the cycle starts, the compressor turns off so the evaporator coils can warm up. Once the coils reach between 35 and 50 degrees Fahrenheit, the thermostat signals to the compressor to turn back on and cool things down.
If the defrost timer and thermostat are faulty, the compressor will not be signaled to turn off. It will run constantly. Since the communication between these components involves electrical currents, it is best to have a qualified technician service the problem.
A tight seal is required to keep the inside of your food at safe temperatures. If the seal is not tight, warm air will get in and the compressor will run constantly in order to compensate for the humidity.
You can check the seal of your refrigerator by closing a piece of paper in the door. When you try to pull the paper out, there should be some resistance. If there is no resistance, the seal is bad and needs to be replaced.
Evaporator Fan Motor
The evaporator fan keeps air circulating around the evaporator coils while the compressor is running. The fans work together to expel heat. If the evaporator fan is faulty, cool air will not be circulating thru the fridge and the compressor fan will run constantly.
Samsung Fridge Fan Not Getting Power
If your Samsung freezer is nice and cold but the refrigerator is not cool, it is possible the evaporator fan is not getting power. Use a multitool to test the fan for continuity. If the fan is getting power, the next component to test is the control board.

The control board is the brain behind the compressor and fan motors. It sends voltage to these fans. If the control board is faulty, these fans will not receive power even though they work. A service technician will need to replace the control board.
If the Samsung fridge fan is not getting power, the thermistor could be faulty. The thermistor monitors the temperature inside the fridge, sending readings to the control board. If the thermistor is defective, the compressor and evaporator fans will not be signaled to turn on and cool the fridge.
