Samsung Refrigerator Freezing Up (Top Fixes !)

I’ve been seeing a lot of people complaining about their Samsung refrigerator freezing up. If you’re among these people and you’re looking for help, I’ve got a solution for you!

I did some research and I found out that if your refrigerator keeps freezing up, it’s usually due to a defective defrost system, overpacked refrigerator, temperature control issue, faulty defrost thermostat and so on.

You wanna find out how to go on about dealing with these stuffs? Continue reading as we dive into more causes of this problem and the ways to fix them.

Why Does My Samsung Refrigerator Keep Freezing Up?

Have you ever opened your Samsung refrigerator only to discover a frosty surprise? 

This can be a very frustrating experience, and understanding the reasons behind it is the key to resolving the issue. 

1. Inadequate Air Circulation (Blocked Vent)

A major contributor to refrigerator freezing up is obstructed air circulation. It’s required that there’s sufficient flow of air in and out, most especially at the back of the unit. 

Make sure the refrigerator is at least 5 –10 cm away from the back wall. This is important for a smooth flow of air within the fridge.

Also, when vents are obstructed, cold air won’t be able to circulate properly, and this leads to uneven cooling and frost all over your food items.

In situations like this, what you need to do is check for any obstructions around vents. 

To do this, you can use a vacuum cleaner to get rid of dirt and debris. 

Sometimes, overloading your refrigerator can also cause the unit to freeze up. Spread out the items in the refrigerator to avoid overloading.

2. Temperature Control Problem

Issues with the temperature control mechanism can occur in two ways. This could be due to incorrect temperature settings or a faulty defrost thermostat.

A temperature control problem may disrupt the balance between cooling and defrosting cycles. So, you need to ensure that the temperature settings are accurate and not too low.

Adjust the temperature settings and make sure it’s between 37.4 °F and 41 °F. If after you’ve done this and the problem still persists, then you need to check the status of the defrost thermostat.

Turn the thermostat all the way up. This should produce a click sound. But if you don’t hear this, then something is obviously wrong with the thermostat.

Regularly calibrate or replace the thermostat to ensure accurate temperature control. Depending on your location, replacing the defrost thermostat should cost around $200.

3. Defective Defrost System

This is arguably the major cause of this problem. It is a system that basically comprises the defrost timer, the defrost thermostat and heater.

The defrost system is designed to melt accumulated ice regularly, while maintaining optimal conditions.

If this system is defective or starts to malfunction, it can lead to excess ice accumulation.

To fix this specific issue, inspect the defrost heater, thermostat, and timer for any issues. A malfunctioning defrost system can also affect other functions.

If you’re planning on fixing this yourself, make sure the unit is unplugged. I usually remove the contents first after unplugging, then I’d visually inspect the thermostat, timer and heater to check for any damages.

Test the components with a multimeter if you’re dealing with the control panel. However, if you’re getting incorrect readings or nothing at all, this is a sign that it’s gone bad.

You’ll need to replace the faulty parts that’s not responding.

4. Faulty Door Seal 

I found out that a compromised door seal is another cause of a Samsung refrigerator that keeps freezing up.

When the door seal is damaged, warm air infiltrates and finds its way inside the unit. Then it condenses and freezes into water droplets as soon as it gets in contact with the cold air inside the refrigerator.

I hope you get the logic around this.

Now, you have to inspect the door seal for any cracks or gaps and replace it if necessary. 

5. Faulty Damper Control Assembly

Just like other components in a refrigerator, the damper control assembly controls and regulates the cold air flow from the freezer to the fridge compartment.

Your refrigerator would start overcooling and freezing up if the damper control is malfunctioning. 

One way to.fix this problem is to examine and check for any issues with the damper control assembly.

Locate the faulty damper control assembly – you would usually find it inside the refrigerator air towel or in the air duct.

Inspect for some visible damages while testing the continuity with a multimeter. If you find any underlying issues, fix it or find a replacement.

6. Clogged Freezer Drain

If your Samsung refrigerator is freezing up, a clogged freezer drain might be an issue too. 

When a freezer drain is clogged, this prevents proper drainage of melted ice, which leads to ice/frost buildup.

To address this problem, the simplest solution is to unplug the fridge, access the defrost drain, and pour hot water down the hole.

Make sure to use a turkey baster. Perhaps you don’t have a turkey baster, you should consider purchasing one or simply ask your neighbor if they’ve got one.

Doing this, you wouldn’t have to buy a turkey baster again.

Frequently Asked Questions!

Samsung refrigerator ice maker freezing up?

Before I forget….It’s worth mentioning that the ice maker too can cause a refrigerator to freeze up. This usually happens if air gets leaked in the ice compartment, resulting in moisture.

Locate the dispenser bucket in the refrigerator door and inspect the unit for any signs of leakage

If you detect any air or water leaks within the ice maker, it’s recommended that you replace the whole component instead of repairing.

Although, you can use a temporary repair method by sealing the ice maker with silicone.

Should I Keep Manually Defrosting?

Perhaps you’re wondering whether you should manually defrost a Samsung refrigerator that keeps freezing up, here’s what I think you should do.

I don’t recommend manually defrosting a fridge that is meant to have auto-defrost. 

Just make sure the fridge is far enough away from the wall. Check if the condenser piping is properly clean, is it? If not, clean it very well.

If there’s a drain hole in the fridge, make sure that it’s clear and that the evaporator pan at the back is clean. 

However, remember that not all fridges have this as a means of removing water after auto-defrost because there are other methods.

Adjust the thermostat and set it correctly. You want a temperature of 3 or 4 degrees Celsius. Warmer is too warm, 2 degrees should be OK and 1 degree or colder is too cold.

I hope this helps! Actually If you’re handy and a good DIYer, you can easily fix most of these problems yourself otherwise get in touch with a technician.
