Samsung refrigerators are built to last, but like any appliance, they can develop issues over time — especially cooling problems in the fresh food section. In this article, we’ll walk you through how to diagnose and repair one of the most common problems with Samsung refrigerators in Houston: ice buildup on the evaporator that leads to poor cooling and loud fan noise.
So, what’s the most common issue Samsung fridge owners face?
One of the top complaints is that the fresh food compartment is too warm or not cooling at all. Another common symptom is a loud noise coming from the fan when the door is closed. In many cases, these are signs of the same underlying issue — frost buildup on the evaporator.
What’s Causing the Problem With Samsung Refrigerator?
This is usually due to ice formation on the upper part of the evaporator, which blocks the fan and prevents airflow from circulating cold air into the fridge section.
Can this be fixed by yourself?
Technically, yes — but there’s a catch. The evaporator is made of fragile aluminum tubing. If you don’t have experience working with it, you could easily damage the sealed system, turning a moderately priced repair into a $1000+ job.
So, should you repair it yourself? That’s up to you. But let us walk you through the full process first:
Step-by-Step: Samsung Refrigerator Evaporator Repair
Unload all food and remove all the shelves, including the large bottom shelf.
Unscrew the panel (cover) at the back of the fresh food section.
Use a plastic spatula to gently pry it open — there are small arrows showing where to do it.
Now comes the tricky part: you likely won’t be able to remove the cover right away because it’s blocked by years of ice buildup. You’ll need to thaw it first — sometimes it takes up to three hours.
Once the panel is off:
Disconnect the wires from the cover and the back wall.
Use a steamer to melt the ice buildup on the evaporator.
Install a Samsung Leakage Kit (part #DA82-01415A), which includes insulation foam for the evaporator tubing.
In some Samsung refrigerator models, the manufacturer recommends moving the defrost sensor closer to the fan. Instead of placing it on the capillary tube, it’s relocated to the return line (suction side). This helps with more accurate defrost cycles.
A Word of Caution About Extra Heating Mods
Some technicians, tired of repeat visits, install additional heating wires. Sometimes it helps, sometimes it doesn’t. If Samsung does not recommend it for your model, we advise against it — it increases load on the main control board and power consumption overall.
Final Steps and Hidden Fixes
Don’t forget the two rubber one-way valve tubes located at the back, in the compressor compartment. Over time, these tubes dry out and allow warm air to enter, which then freezes in the upper evaporator. This causes the familiar ice dome that blocks the fan and leads to noise and eventual airflow failure.
Replace these tubes as part of the Samsung kit to avoid repeat issues.
Powering Back On
Once everything is reassembled, plug the fridge back in. Don’t worry if it doesn’t start immediately — Samsung fridges usually delay power-up by 15 to 45 minutes after reconnection.
Commonly Affected Samsung Refrigerator Models
The following Samsung models, including the RF30HBEDBSR, are often affected by evaporator icing and fan blockage in the fresh food compartment:
Samsung RF30HBEDBSR
Samsung RF28HFEDBSR
Samsung RF263BEAESR
Samsung RF25HMEDBSR
Samsung RF28HMEDBSR
Samsung RF260BEAESR
Samsung RF23HCEDBSR
Samsung RFG298HDRS
Samsung RF31FMEDBSR
Samsung RS25H5111SR
If your fridge is on this list and you’re experiencing noise after door closure or poor cooling in the fresh food section — you’re most likely facing the same evaporator ice buildup issue.

Can You Fix It Yourself?
Yes, in some cases — but be very careful. Here's how:
Unplug the refrigerator. Always start with safety.
Remove all food and shelves from the fresh food compartment.
Attempt to remove the rear evaporator panel. If it’s stuck, there’s ice buildup — wait until it thaws (this may take 2–3 hours).
Disconnect all connectors and remove the cover.
Carefully steam the ice off the evaporator using a handheld steamer.
Install the Samsung leakage kit (DA82-01415A) with insulation and reposition the defrost sensor if needed.
Replace the two rubber drain tubes in the compressor compartment.
Reassemble and plug in the unit. Wait 15–45 minutes — this delay is normal in Samsung refrigerators.
⚠️ Warning:
The evaporator is made of fragile aluminum tubing. Damaging it can lead to a sealed system failure, turning a $400 job into a $1000+ repair.

Frequently Asked Questions
If the fresh food section is warm but the freezer is fine — or if you hear a loud fan noise when the door is closed, it likely means ice buildup on the evaporator.
Yes, if you’re careful. You can remove shelves, thaw the ice with a steamer, and install the Samsung repair kit. But damaging the aluminum evaporator can turn it into a $1000+ repair.
No. The fan motor can burn out or break, and your food may not stay safe due to poor airflow.
Typically 2 to 3 hours depending on the amount of ice and access to the evaporator. Most repairs are completed in a single visit.
