It’s normal to expect your appliances to continue working well after a power outage as a homeowner. Unfortunately, this isn’t always the case. If you have a Samsung refrigerator in your kitchen, for example, you may notice that it does not restart cooling after the power is restored.
We’ll walk you through each stage of troubleshooting your Samsung fridge that won’t cool down after a power outage in the sections below.
First, perform a power reset
When the power is restored after a power loss, your refrigerator should function normally. Of course, depending on how long the power loss occurred, your refrigerator may take longer to return to its original temperature.
If the fridge still won’t cool down after an hour or two, you’ll need to start diagnosing the problem.
What’s the first step?
Restart your computer with a simple power reset. That implies you’ll have to turn off the fridge’s power again for a while. To do so, locate and turn off the dedicated breaker for your refrigerator.
Leave it alone for at least five minutes once it’s turned off. After that time has gone, turn on the breaker and turn on your Samsung refrigerator.
What is the purpose of this?
Turning it off and on again, much like anything with electrical or electronic components, is sometimes the most basic cure.
This allows all of the components inside the refrigerator to power down and hopefully resume normal operation.
Second, reset the main control board
You should leave the fridge alone for 30 minutes after conducting a power reset. That should be enough time for it to significantly cool down.
If a power reset does not solve the problem, the next step in your troubleshooting process is to reset the main control board. Let’s take a deeper look at what that is and how you’ll go about performing it.
Let’s start by agreeing on the definition of the Main Control Board. Simply, that is your Samsung refrigerator’s brain. It resembles a circuit board with several electronic components on it.
The control board is in charge of coordinating and powering all of the fridge’s various components, including the cooling mechanism that keeps the temperature inside the compartments low.
How the reset can be done:
- Press and hold the Power Freeze and Power Cool buttons simultaneously until you hear a chime to reset the Main Control Board in your Samsung refrigerator. That should be enough to restore functionality to the Main Control Board.
- If it doesn’t work or you’re unclear of the processes, it’s usually a good idea to consult the user manual that came with the refrigerator.
- You’ll find more thorough instructions there that are specific to your Samsung refrigerator model. Simply follow those steps and, if necessary, reset the Main Control Board.
It should be possible to get it working again by simply resetting the main control board. If this is not the case, proceed to Step Three.
Third, Inspect the Compressor
Let’s say that resetting the Main Control Board didn’t help, and the fridge is still warm 30 minutes later. If that’s the case, the next step in troubleshooting the problem is to inspect the compressor.
Let’s start with a quick recap:
The Main Control Board, as previously stated, is the brain of your Samsung refrigerator. The compressor, on the other hand, is similar to the heart.
Its duty is to compress the refrigerant and assist it to circulate throughout the fridge’s cooling system, as its name implies. It will assist lower the temperature within the fridge compartments and keep them cold if it is working properly.
To identify the compressor and troubleshoot this item, pull the fridge out slightly. It’s usually found near the rear of the fridge, nearer the ground.
1. Pay attention to the compressor
Keep an ear out for any sounds. A slight hum from the compressor indicates that it is still operational. Before continuing to troubleshoot your refrigerator, allow it some time to cool down (30-60 minutes).
Assume, however, that the refrigerator compressor is silent. In such a situation, one of two things could have gone wrong: the inverter board or the main control board.
2. Look to see if the main control board has failed
The role of the Main Control Board was previously discussed in Step Two. It’s possible that resetting it didn’t help, and the compressor isn’t operating.
In that situation, it’s also possible that the board is no longer functional.
Why Does It Fail?
The Main Control Board of your refrigerator could fail or be damaged for a variety of reasons. Simple wear and tear, which is more likely if the fridge has been in use for a long time, is one of the most typical explanations.
Aside from that, moisture or extreme heat could have gotten into the control board and harmed it.
Assume, however, that you have recently undergone a power outage. In that circumstance, your refrigerator’s Main Control Board is more than likely to have been shorted out.
When electricity is restored after an outage, power surges are typical, and this can be terrible news for your household appliances that are still plugged in.
It can be difficult to replace the primary control board. First and foremost, you must obtain the correct replacement part. Please consult the refrigerator’s User Manual as well as any technical sheets that may have been included with the device.
Once you’ve got it, you can correct it by:
- To avoid any chance of damage or electrocution, disconnect the fridge’s power source.
- Locate the access panels you’ll need to remove to get to the existing Main Control Board, as directed in the user handbook.
- You should photograph the board so that you can refer to it later.
- Remove any screws holding the board in place, as well as any wire harnesses that are attached to it.
- Replace the old board and reconnect it in the same manner.
- Refer to the photo you took previously if you’re unclear about anything. That will come in handy when it comes time to replace the screws and any electrical connectors.
3. Inverter Control Board Failed
Aside from the Main Control Board, the Inverter Board is another important component.
This board performs the same purpose as the Main Control Board, except it, is exclusively for the compressor. That is, it coordinates the compressor’s activity and supplies electricity when it is required.
Why Does It Fail?
The Inverter Board is similar to the Main Control Board, except it only serves the compressor, as previously stated. As a result, it may likewise fail for the same reasons.
To begin with, the board could have developed a flaw as a result of normal wear and tear after being in use for so long. Furthermore, it’s likely that water or excessive heat has harmed its components.
Given that we’re talking about a Samsung fridge following a power loss, it’s plausible that an electrical surge destroyed the board when the power was restored.
- To avoid injury or electrocution, start by turning off the refrigerator’s power.
- The inverter control board will be hidden behind an access panel at the back of the Samsung refrigerator. To be certain, look for that panel in the User Manual or on any technical page.
- To obtain access to the inverter control board, remove the screws that hold the panel in place. This board also has a lot of electrical connectors attached to it, so snapping a snapshot to serve as a reference later is a good idea.
- Depress the tabs that keep the board in place and disconnect the electrical connectors one at a time.
- Replace the new board and, when reinstalling the electrical connectors, refer to the reference photo you took earlier.
- Because there are so many different electrical connectors, it’s critical to properly organize them before replacing the access panel you opened earlier. This will eliminate any future issues, such as those caused by faulty electrical connectors.
