Samsung One Connect Box Overheating: 5 Causes And Fixes

Now, we will dive deeper. If you manage to learn about all the problems and their solutions properly, you may not need to hire any professional or seek a warranty to fix the Connect Box overheating problem. Let’s check out the causes, why they happen, and how to fix them elaborately.

Problem 1: Poor Ventilation

It’s not very common that your Samsung One Connect Box causes excessive heating because of poor ventilation. Still, you should remember that the One Connect Box is very poorly designed in terms of heat elimination. 

When you store this unit in a closed cabinet with very little ventilation or a bookcase, your unit will likely overheat. But most users don’t usually find this problem. Still, some of them reported that their unit started overheating when they placed it in a congested area like in a cabinet.

How To Fix

As you know, Samsung One Connect Box ventilation can be a serious issue if you don’t keep the Box in a proper state. In this case, the Box may not get enough air around it. Commonly, people keep the Box in a cabinet so the Box doesn’t get enough air.

If you are guessing that your Connect Box is overheating because of poor ventilation, you should follow the steps below:

• Firstly, make sure that the One Connect Box is placed in a well-ventilated area.
• Ensure that there is enough space around the box for air to circulate. 
• Avoid placing it in enclosed spaces or stacking objects on top of it.
• Don’t use a cover over the Box.
• Don’t place it on a cushioned surface like on a carpet.

If the Box is still overheating after you ensure it’s getting proper air around it, it must accumulate dirt inside it. This is another reason, we’ll discuss afterward.

Problem 2: Improper Placement

This is not the same thing about air ventilation even if both facts are about the placement. Still, if you place the box in a well-ventilated area, there can be a specific reason your Connect Box is getting heated. 

It’s about placing the Box in a place that is normally hotter than other areas in your place. Any spot that gets direct sunlight isn’t a good place to keep your One Connect Box. Placing your unit close to a radiator or any kind of heat source is also a BIG NO. This will cause your unit to overheat for sure.

How To Fix

Fixing these Samsung One Connect Box issues is easy. You just need to choose a proper and appropriate place for the box. You should consider the following facts while choosing the place to keep your Samsung One Connect Box:

• Choose a cool and open space.
• Avoid a place where sunlight directly falls.
• Don’t place it on a surface that can get heated easily; like a thermal pad or aluminium surface.
• Don’t place the box near any heat source like your chimney or heater.
• Avoid placing it near an electric object that can produce heat like your Fridge, iron machine, oven, etc.
• Don’t place it near the kitchen.
• Avoid keeping it inside a congested area that can hold the heat for a long time.

So, all you have to do is choose a pace that can keep your Samsung One Connect Box cool and safe.

Problem 3: Dirt Accumulation

When your unit runs for a year or longer without cleaning, you can expect a fair bit of dust to accumulate. The amount of dust will depend on how dusty your home can get. But as a general guideline, cleaning your unit every year is a good idea. 

However, if you check properly, you must see that there are many holes in the boxes from where dirt can gather inside. Also, in the worst scenarios, these holes can be completely blocked by dirt.

If your box has already gotten enough dirt inside, it can malfunction, especially the fan. So, you can get an overheated Samsung TV cooling fan overheated error message. 

How To Fix

If your Connect Box has already accumulated enough dust, you can get it when you look closely. You can blow a mouth full of air inside these holes and you’ll see dust will come from the inside part. 

However, if it’s dirt that is causing the issue, you need to clean it. Now the question is, should you do it yourself? Well, if you are good with devices and have the necessary technical experience, you can do it all alone. Otherwise, you should ask a professional to clean it for you.

Cleaning The Connect Box

So, if you are quite confident that you can clean the inside part of the Connect Box, it’s good. Here are the simple steps you can follow for the process:

Step 1: Preparation

First, you have to turn off and unplug the TV. Then, place the One Connect Box on a flat, elevated surface. You should also keep your toolbox with screwdrivers and other tools near your hand.

Step 2: Remove the Back Cover

When you are ready to start, you should begin by removing the back part of the box. Simply unscrew the six screws on the back cover of the One Connect Box. Gently lift the cover to expose the internal components. 

While removing the case, stop as soon as you feel something is adjacent to the part. You have to make sure that no wire is still attached to the back part so that it can’t be torn. 

Step 3: Disconnect and Remove the Circuit Board

When you successfully remove the back part of the case, it’s time you should separate the board from the case. For that, you have to first, identify the circuit board connected to the fan. Remove it from the fan by unscrewing all the screws.

Step 4: Unplug and Clean the Fan and Motor:

Take out the fan by removing the screws holding it in place. Clean both the fan blades and the motor using a brush and compressed air or a can of electronics cleaner. Remove accumulated dust to improve ventilation.

Remember that the error message you get is all for the dirt inside the fan. So, use a painting brush to clean the fan.

Step 5: Oil the Motor (Optional)

You can apply a small amount of oil to the fan motor’s shaft using a dental tool or a similar device. This step is completely optional but it can help in smoother operation. Make sure not to over-oil.

Step 6: Clean the Circuit Board

Not just the fan, your unit mainboard can be full of dirt if you don’t clean it for a long time. So, you need to clean the board as well. Use the same paintbrush and gently clean it.

Step 7: Reassemble the Unit

Finally, when all the parts are cleaned, you have to reassemble them together. For that, first, place the fan back into its position and make sure that all screws are securely fastened. 

Now, reconnect the circuit board to the fan, and carefully reassemble the One Connect Box by putting the back cover back on. Use a bit of anti-seize on the screws for easier disassembly in the future.

By following these steps, you can maintain and clean your Samsung One Connect Box properly. Once it is clean, hopefully, the overheating issue won’t appear so easily.

Problem 4: Samsung One Connect Box Cooling Fan Issues

Another common fact that causes your Connect Box to get overheated is the fan that is malfunctioning or broken. There can be many reasons why the fan can be broken. The most common cause is excessive dirt inside it.

However, not just the dirt, if your connect box is overheated repeatedly, it can start malfunctioning and finally get broken as well.  

How To Fix

From the previous problem’s solution, you must have a clear idea of how to open the box to get the fan, right? If yes, all you need is to open the box and check if the fan is alright. If you have no visible problem or there is not a lot of dust, I guess, it’s a different issue.

However, the fact is what to do if the fan is not okay. In the previous problem’s solution, I have elaborated on how you should unplug the fan from the case, So, just take it out.

You will have to buy a new fan for the Connect Box. You’ll get it easily in any tool and electric store and it might cost around $50. Now, you have to replace the Fan. As you take the older one out, just set the new one and reassemble the unit.

Hopefully, the problem will be fixed now. If not, there is a possibility that you didn’t manage to assemble the new fan properly or the fan doesn’t support the Box. That’s why you should check twice while buying the new fan and assemble it properly.

Problem 5: Malfunctioning Component

Not just the Fan, but any component inside the Connect Box can get broken. And that can be a good reason, the complete unit acts weirdly and overheats unusually. Now, the question is how you can get a hint about the malfunctioning component, right?

If your Box is overheated and there are no other issues like dirt, placement, heat, or prolonged operation, you must open the unit. At this time, you should first check the fan. If it’s good, then you should consider that there can be an issue with any of the other components.

Sometimes, an inside component of the Samsung One Connect Box can get burned. In this case, you will get a burned smell from the Box.

How To Fix

Firstly, you should check out all the components for any visible damage like burned or broken parts. Generally, a Connect Box has the following parts:

• Processor (CPU)
• Graphics Processing Unit (GPU)
• Memory (RAM)
• Storage (e.g., Flash Memory)
• Motherboard
• Power Supply Unit
• Cooling System
• Connectivity Ports
• Wireless Communication Modules
• Input/Output Interface Controllers
• Sensor(s)
• Firmware/Software Chips
• Ethernet Controller

If there is any part broken or burned, you should look for a way to change it. If it’s an easy part like a port or a chip, you can easily replace it with a new one if you have minimum technical knowledge. 

But if it’s with the board, processor, or GPU, you better ask a professional to help you replace it. I can’t guarantee that you will find all these parts in the market. If it’s available in the electrical stores, you should consider yourself lucky.

If you can’t find them in the market, you can ask the technician store for the component. Sometimes, they gather old and broken units and when other units have a broken part, they utilize the older one. If you can’t manage the part, you should ask the Samsung Service Center to fix it for you.

Problem 6: Continuous Power Supply

When you keep the TV and the Connect Box turned on for a long time, the Box will get a continuous power supply. This is another common reason your Samsung One Connect Box can get Overheated. 

For this prolonged operation, the Box doesn’t commonly get excessively heated but mildly. In this case, you don’t need to be worried at all. As the connect Box ventilation system is not so upgraded, producing mild heat is not an issue.

But you should be concerned if there is no other issue and your Box is overheated after you use it for a long time. 

How To Fix

Try to remember how long the TV is connected to the Box and it is powered on. If it’s for a long time for about more than 8 hours, you should give it a rest. Power off the Box and wait for a while. At this time, give a recheck about the placement. 

After a while, the Box should be cooled down. After it’s perfectly at room temperature, turn it on and see how it’s doing after an hour. If it’s good, then just remember to give it a short break every 3 to 4 hours.

iv) Power Off The TV And The Box When Not Using

Sometimes it happens that no one is watching the TV, still it’s still running on. Also, many of us keep the TV powered on and never just powered off. These facts cause non-stop power supply to the TV and Box. 

Surely, it’s not a good habit. You should keep them powered off when you are not using them. This is eventually good for both devices.

v) Don’t Use The TV With The Highest Brightness

Using your TV with the highest brightness can create extra pressure on the Connect Box. As a result, it can be overheated. But this is not a common issue and professionals just assume this fact as a possible cause. 

However, using Full brightness is not also good for your eyes. So, keep the brightness level in between 60% to 80%.

When the TV has outdated software and firmware, it can cause a lot of system-based issues, and that can create extra pressure on the Connect Box. As a result, it can work in unusual ways and there is a possibility that the connect Box will get overheated.

In any case, if you don’t know how to update the software of your Samsung TV, follow the steps below:

• Use your TV remote to press the Menu button.
• Go to Settings and look for the option, Software Update or Update Now.

Your TV will reset and wait till it is turned on. If the Auto-update option is available, keep it activated to get the updated software always.
