Samsung refrigerators with Twin Cooling or dual evaporator systems are popular because they control the refrigerator and freezer sections separately. In many models, the freezer has its own evaporator, and the fresh food section has a separate evaporator and fan behind the rear inside panel.
This design can work very well when everything is clean, sealed, and draining properly. But after several years of use, especially in a humid climate like Tampa, FL, some Samsung refrigerators develop a common problem: the upper part of the refrigerator evaporator starts freezing over.
At first, the customer may hear a light fan noise. Then the refrigerator section may stop cooling correctly. The freezer may still work fine, but the fresh food section becomes warm. In many cases, when the rear panel is removed, there is ice buildup around the evaporator and fan area.
At Appliances Fix & Care LLC, we see this issue often on Samsung refrigerators in Tampa Bay homes.

Common Symptoms of This Samsung Refrigerator Problem
If your Samsung refrigerator has this issue, you may notice:
- The refrigerator section is warm, but the freezer is still cold
- Fan noise coming from the back wall of the refrigerator section
- A grinding, buzzing, or rubbing sound when the fan hits ice
- Water or moisture inside the refrigerator
- Food spoiling faster than normal
- The temperature on the display looks normal, but the actual temperature is too high
- Ice buildup behind the refrigerator’s rear inside panel
- Cooling returns after defrosting, but the same problem comes back again
This is not just a simple “dirty fridge” problem. In many cases, the refrigerator section evaporator keeps freezing again and again.
Why the Evaporator Freezes in Samsung Dual Evaporator Refrigerators
Samsung Twin Cooling refrigerators use separate cooling systems for the freezer and refrigerator compartments. This helps maintain better humidity and temperature control, but it also means the fresh food section has its own evaporator, fan, air channels, sensors, and defrost system.
When warm, humid air enters the refrigerator section, moisture can freeze on the cold evaporator. Over time, this ice buildup can grow near the upper part of the evaporator. Once the ice reaches the fan area, airflow becomes restricted or blocked.
When the fan cannot move cold air through the fresh food section, the refrigerator temperature rises.
In Tampa, this problem can be worse because of Florida humidity. Even a small air leak, weak door gasket, damaged foam seal, or poor airflow can create repeated frost buildup.
Why Defrosting Alone Usually Does Not Fix the Problem
Many homeowners unplug the refrigerator or manually defrost the ice. Sometimes the refrigerator starts cooling again for a few days or weeks. But if the root cause is still there, the ice comes back.
That is why this issue often becomes a repeated service problem.
A simple defrost may remove the ice temporarily, but it does not always solve:
- Weak or damaged door gaskets
- Air leaks around the evaporator cover
- Poor sealing around the fresh food compartment
- Moisture entering the refrigerator section
- Fan obstruction
- Drain or airflow issues
- Insufficient heat in the problem area during the defrost cycle
This is why a proper diagnosis is important before replacing random parts.
The Expensive “Perfect Repair”: Replacing Gaskets and Sealing Every Air Leak
Technically, the best factory-style approach is to eliminate every possible source of warm air entering the refrigerator compartment.
That may include checking or replacing:
- Refrigerator door gaskets
- Mullion flap seals
- Evaporator cover seals
- Foam insulation seals
- Drain components
- Air ducts
- Fan assembly
- Defrost sensor or thermostat
- Defrost heater
- Control-related components, depending on the model
The problem is that this repair can become expensive quickly. On some Samsung refrigerators, replacing multiple gaskets, panels, seals, and related parts may not be affordable compared to the age and value of the appliance.
For many customers, especially if the refrigerator is already 3–4 years old or older, the full repair may not make financial sense.
A Practical Solution: Additional Flexible Heating Element
In many Samsung refrigerator cases, a practical and cost-effective solution is installing an additional flexible heating element in the refrigerator evaporator area.
The goal of this additional heater is to help reduce recurring ice buildup in the upper evaporator section where the frost usually starts. When installed correctly, it can help prevent ice from growing into the fan area and blocking airflow.
This is especially helpful when:
- The fresh food evaporator keeps freezing at the top
- The fan gets blocked by ice
- The refrigerator section becomes warm
- The freezer still works normally
- Manual defrost only fixes the problem temporarily
- Full gasket and seal replacement would be too expensive
This is not a DIY repair. The heater must be installed safely, in the correct location, and only after the technician confirms that the refrigerator is a good candidate for this repair.
Why the Fan Gets Blocked and the Refrigerator Gets Warm
The evaporator fan is responsible for moving cold air through the refrigerator section. If ice builds up near the evaporator and reaches the fan, the fan may slow down, make noise, or stop completely.
Once airflow stops, the refrigerator section cannot cool properly.
This is why many customers say:
“My freezer is fine, but my refrigerator is warm.”
That symptom is very common when the refrigerator evaporator fan is blocked by ice.
Should You Replace the Fan?
Not always.
Sometimes the fan motor is still good, but it cannot spin because ice is blocking the blade. In that case, replacing the fan without fixing the ice buildup problem may not solve anything. The new fan can become blocked again.
A good technician should first determine whether the fan failed electrically or whether it stopped because of ice obstruction.
Why This Happens More Often in Florida Homes
Tampa homes deal with heat, humidity, frequent door opening, garage refrigerators, and high indoor moisture levels. All of these conditions can make frost problems worse.
If a refrigerator door does not seal perfectly, humid air enters the compartment. When that moisture reaches the cold evaporator, it freezes. Over time, the ice buildup becomes large enough to affect airflow.
That is why gasket condition, door alignment, and proper sealing are very important in Florida.

At Appliances Fix & Care LLC, we repair Samsung refrigerators throughout Tampa and surrounding areas. We diagnose the problem before recommending parts or repairs.
When we inspect a Samsung refrigerator with this issue, we check:
- Fresh food section temperature
- Freezer temperature
- Evaporator ice pattern
- Fan operation
- Door gaskets
- Air leaks
- Drain condition
- Defrost components
- Evaporator cover condition
- Whether an additional flexible heating element is a practical solution
Our goal is not just to melt the ice. Our goal is to help stop the problem from coming back.
When to Call a Technician
You should schedule Samsung refrigerator repair if:
- Your refrigerator section is warm
- Your freezer still works but the fridge does not
- You hear fan noise from the refrigerator section
- You see frost or ice behind the rear panel
- The refrigerator works after defrosting but fails again
- Food is spoiling even though the display shows normal temperature
The earlier the problem is diagnosed, the better. If the fan continues hitting ice, it can eventually damage the fan motor or other components.

FAQ Section
Why is my Samsung refrigerator warm but the freezer is cold?
This often happens when the refrigerator section evaporator fan is blocked by ice. The freezer may still cool normally because it has a separate evaporator, but the fresh food section cannot circulate cold air.
Why does my Samsung refrigerator fan make noise?
A common reason is ice buildup around the evaporator fan. When the fan blade hits ice, it can make a buzzing, grinding, or rattling noise.
Can I just defrost my Samsung refrigerator?
Manual defrost may temporarily restore cooling, but if the root cause is not corrected, the ice buildup can return.
Does my Samsung refrigerator need a new fan?
Not always. Sometimes the fan is good but blocked by ice. A technician should inspect the fan, evaporator, and defrost system before replacing parts.
What is an additional flexible heating element?
It is an added heater installed near the refrigerator evaporator area to help prevent repeated ice buildup in the problem zone. It must be installed professionally and only when appropriate for the model and condition.
Is this repair worth it?
In many cases, yes. If the sealed system and compressor are working properly, solving the evaporator ice buildup issue may be much more affordable than replacing the refrigerator.
