Samsung Refrigerator Not Cooling

Jeegna | 09-10-2023

When a refrigerator stops cooling, it becomes a pressing matter as it affects the freshness of our food and our well-being. Samsung refrigerators seem to have this issue more frequently. However, most of the cooling problems can be resolved easily.

Here are some solutions you can try before calling a technician for help. In some cases, the error code is a combination of lit parts of the panel. Resetting the fridge will erase the code. It’s helpful to photograph the panel before performing the reset.

If the refrigerator is still not cooling, you can also check the power supply by ensuring that the power cable is securely plugged into the outlet. If the issue persists, you may need to turn off power at the circuit breaker, wait 5 minutes, and then restore power.

Samsung Refrigerator Not Cooling

When Samsung refrigerators stop cooling, it could be due to various issues like dirty coils, malfunctioning fans, or defective components. First, check the evaporator fan, which helps to distribute cool air from the freezer compartment into the refrigerator compartment. The next component to check is the evaporator fan. This fan is crucial for proper cooling.

Also, inspect the thermistor responsible for temperature monitoring. Other causes include incorrect temperature control settings, faulty seals, or clogged drains. While some problems can be fixed with a screwdriver, others may require professional assistance. Before attempting any repairs, explore all possibilities and systematically troubleshoot the issue.

Double Check Samsung Refrigerator Power Outlet

Ensure That Samsung Refrigerator and Freezer Doors Close Properly

Set the Correct Mode

Reset Temperature Controls

If your Samsung refrigerator isn’t cooling, it’s important to check the temperature control settings. Experts recommend keeping the temperature between 33°F and 40°F. If it’s too high, the freezer and ice maker won’t work properly.

Reset Temperature Controls

To fix this issue, adjust the temperature controls for both the freezer and refrigerator. Over time, check the accuracy of the settings as refrigerators can experience temperature changes. Put a thermometer inside for a week to determine if adjustments are needed.

Clean the Condenser Coils

Inspect the Start Relay

If your Samsung refrigerator isn’t cooling, check if the condenser fan is working correctly. Then, inspect the start relay attached to the compressor. This part powers the motor unit, and without it, the compressor won’t work, and the fridge won’t cool.

Inspect the Start Relay

To see if the start relay is functional, turn on your refrigerator to check for activity in the compressor. If there’s no movement or buzzing sound, unplug your fridge and remove the compressor relay gently. Shake it lightly to see if you hear rattling noise or small particles falling out.

Listen for a click from the compressor when starting your refrigerator; if it clicks off promptly, replace the start relay as soon as possible.

Verify the Operation of the Evaporator Fan

For Refrigerators with a Single Evaporator

To access the evaporator fan in classic Samsung refrigerator models, remove the light mountings and look up through the casing. If you need direct contact with the fan, you may have to remove the entire system. The good news is that this doesn’t require advanced technical skills.

Once you can reach the fan, inspect it closely to see if it’s working. If it’s not, it may be faulty or obstructed. To determine if it’s faulty, perform a simple experiment with the door switch. This switch controls the fan’s motion and the lights’ activation.

Closing the refrigerator doors triggers the door switch, but you can simulate this by pressing the switch with your hand. If the evaporator fan is in working order, it should start automatically after a few seconds.

For Refrigerators with Dual Evaporators

Refrigerators with dual evaporators have two of them. To check the evaporator fan motor, gently separate the refrigerator and evaporator panels while keeping them connected. This will fully expose the fan.

Close the refrigerator doors and quickly reopen them after a few minutes. If the fan is still in motion before it stops, it’s working correctly. If it remains stationary after multiple attempts, it may be defective.

Inspect the Evaporator(s)

If you’ve checked the evaporator fans and they’re working, it’s time to examine the refrigerator’s evaporator. Samsung refrigerators have evaporator coils consisting of copper tubes. They are usually located behind the freezer and generate cold air. The evaporator fan then circulates this air into the refrigerator section.

Inspect the Evaporator(s)

Newer Samsung models have dual refrigerators with separate evaporators for the freezer and refrigerator sections. This design allows for more precise temperature control in each compartment.

Inspect the Defrost Drain

Refrigerators are complex machines with each part playing a specific role. When one part malfunctions, it can affect the entire unit. The evaporator coils are crucial for cooling and maintaining low temperatures.

The defrost heater prevents ice buildup on the coils. Sometimes, the defrost drain can get blocked, causing excess water and ice buildup during the frost cycle. This can lead to poor cooling performance. To solve this issue, unplug the refrigerator and let it thaw out for a few minutes. Then, use forced air to clear any blockages from the drain.

For Refrigerators with a Single Evaporator

In traditional Samsung refrigerators with a single evaporator, you’ll find the defrost drain located in the freezer, underneath the evaporator coils.

For Refrigerators with Dual Evaporators

In refrigerators with dual evaporators, you’ll locate the defrost drain in the refrigerator, positioned directly beneath the evaporator coils.

When You Need to Order Replacement Parts for Your Samsung Refrigerator:

If you’ve tried our suggestions and found the cause of your Samsung refrigerator not cooling, your final option is to replace a broken part by installing a new main control board or a new thermistor.

To ensure you buy an authentic replacement, look for your fridge’s model number. It’s on a sticker inside the fridge. Make a note of it and enter it into Sears Parts Direct. You can order the specific part you need from there.

Samsung Refrigerator User Manual

If your Samsung refrigerator is not cooling, it is important to refer to the user manual. You can find the manual online at if you don’t have a physical copy. Just enter your model number in the search bar and download an electronic version for troubleshooting advice and other information.

If you reset the fridge and it still doesn’t work, then schedule service, the error codes and other diagnostic information in the main control board will be wiped out. That makes it more difficult for the technician to diagnose and repair the problem.

Samsung Customer Support

If your Samsung fridge isn’t cooling, try our troubleshooting steps. If they don’t work, trained professionals may be needed.

You can call them anytime at 1-800-726-7864 or schedule an appointment online. If you have a warranty, the cost may be covered.


What is the lifespan of a Samsung refrigerator?

Generally speaking, refrigerators live to be 15 years old, though this can vary. A refrigerator appliance normally stops working when it dies unexpectedly, but it’s usually preferable to replace it before that happens.

How do I reset my Samsung refrigerator?

Reconnect the refrigerator’s power after unplugging it for a minute. Resetting your refrigerator to regular mode after unplugging it will restore it if it is in demonstration mode. Call Samsung Customer Service if none of these fixes your cooling issue.

What happens if my Samsung refrigerator thermostat is broken?

A broken refrigerator thermostat may result in systemic issues with the entire appliance. To maintain a cool environment, the thermostat manages the compressor. If not, you can experience a frustrating breakdown, and perishable food might go bad.


If your Samsung refrigerator isn’t cooling, there may be a specific issue causing the problem. Check for a dirty condenser coil, faulty evaporators, defective start relay, or malfunctioning evaporator fan. Luckily, these issues are simple to fix as we have outlined in this guide. We hope that our guide will help you identify and solve the issue quickly. If you need professional assistance, we also provide resources to help you get help.
