During the bootup of your Samsung refrigerator, you may encounter an error code 88, which indicates that there is a communication fault caused by the interruption of the refrigerator‘s power supply.
A power surge has caused a problem with the refrigerator’s circuit, in other words, the refrigerator is not working properly.
A common problem that occurs when the 88 error code is displayed is that the refrigerator‘s temperature decreases.
But the problem is not caused by a failure of the heating or cooling components; rather, it is caused by a malfunction of the control board.
WHAT IS THE CAUSE OF THE ERROR 88?
It appears as a result of a sudden loss of power. The majority of
inverter refrigerators are affected by this problem because they are unstable when exposed to voltage fluctuations, unexpected power spikes, intermittent power supply, power outages, and network short circuits.
In response to fluctuations in the electricity supply, the control board begins sending requests to the various systems to determine whether they are operating properly, but it receives no response. The refrigerator then initiates the self-diagnostic procedure; however, this does not yield any results, and the refrigerator’s response is to display the error code 88 on the display.
All of this results in the occurrence of error code 88.
It appears in the form of a pair of digits 88 that are displayed side by side. Aside from that, the last eight can blink in the range from 8 to 3, showing the numbers 83 to 85 and 86 to 88 respectively.
It is dependent on the type of secondary damage that has occurred – specifically, what has been violated in the unit as a result of the voltage variation. On the main module, the most frequently encountered problems are with a PBA inverter converter, a capacitor for starting the compressor, as well as power boards and electronic components in other subunits.
WHAT DOES ERROR 88 HAVE TO DO WITH IT?
It has to do with the operation of the control board, which, when automatically checked, does not receive signals from the rest of the microcircuits and thus cannot function properly. That the central module is unable to check the system after an emergency power on-off indicates the first stage of equipment diagnostics, which is the first stage of equipment diagnostics.
In other words, because of the inability to complete the test mode, the refrigerator always returns to the beginning of the test mode sequence.

HOW CAN YOU GET RID OF THE PROBLEM AT HOME?
- In order to resolve error code 88 in a Samsung refrigerator, there are three possible solutions:
- to leave the unit for several hours to allow the boards to self-stabilize (that is, to turn it on and not touch anything); to leave the unit for several hours to allow the boards to self-stabilize
- for 1 – 5 minutes, then turn it on again so that the diagnostic system can check the different sensors and subunits (this will clear the incorrect settings, and error 88 will be eliminated); unplug the cord from the outlet for 1 – 5 minutes, then turn it on again
If the first two methods did not yield the desired results, the third option is to force the refrigerator to restart.
Alternatively, it is necessary to press the Energy Saver and Alarm keys (or the Lighting key, depending on the model) simultaneously. Hold them for 8–12 seconds, and then release them, causing the device to return to its normal operating mode of operation.
This will assist it in completing the test and removing the error code 88 from the system.
The Power Freeze and Power Cool buttons on inverter refrigerators from earlier generations should be pressed. Keep pressing the buttons until the display emits a beep and then turns off. This will indicate that the unit has entered the test mode and has begun the process of checking, which will take a few minutes to complete.
How to Resolve the 88 Error Message
There are three different approaches to resolving the 88 error. If they fail, it is likely that the control board will need to be replaced.
Occasionally, if you do not touch the refrigerator for two or three hours, the error code will go away on its own (this means not opening the refrigerator or freezer or turning the power off). In order for the refrigerator‘s system to stabilize itself, it will need some time.
While the refrigerator is going through the stabilization process, the error code will continue to blink continuously.
It is possible to restart the refrigerator in order to see if the problem is resolved sooner rather than later. To restart the refrigerator, unplug it from the power source or turn it off at the circuit breaker for 1-3 minutes, and then reconnect it. If the error code persists, the third method should be attempted. You should be aware that Samsung recommends that you do not turn off your refrigerator because doing so can make it more difficult for a technician to diagnose the problem.
This is due to the possibility that the self-diagnostic information will be erased if the power is disconnected.
System reset can be accomplished through the control panel. Instructions for resetting the device will vary depending on the model. On some refrigerators, you must press the Lighting and EnergySaving buttons at the same time to activate them.
On other models, simultaneously press the PowerFreeze and PowerCool buttons to initiate the freezing and cooling process. For 10-15 seconds, press and hold the buttons.
An audible beep should be heard, and then the display should be turned off. Continue to wait for a few minutes while the system performs self-diagnosis, and then check to see if the error code is still displayed.
If the error code persists, you are most likely dealing with a more serious problem than a temporary glitch; the control board has most likely been damaged as a result of the electrical surge.
Common Causes of Samsung Refrigerator Error Codes 88
1. Ice accumulation on the fan blades
What it is is as follows: Each and every evaporator fan, including the one located inside the freezer compartment, is made up of two components: a motor and fan blades. When those blades turn, they will force air to move, ensuring that cold air is evenly distributed throughout the compartment and reaches all parts of the compartment.
This is why it fails: Unfortunately, moving air can sometimes transport moisture with it. In particular, if the compartment door has been left open for an extended period of time or if warm air has somehow gotten in through a damaged door seal, this is true.
This will cause ice and frost to gradually accumulate around the evaporator fan as a result of this. As the buildup becomes more severe, the ice will begin to obstruct the movement of the fan blades, eventually preventing them from turning altogether.
It is possible that fan blades will be damaged as they turn and hit the ice buildup on a regular basis in the worst-case scenario.
Solution: Defrosting the freezer and allowing the ice to melt naturally is the only safe way to get rid of ice buildup in the freezer. In order to accomplish this, you must turn off the refrigerator while leaving the freezer door open. Because the ice melts slowly but thoroughly, this process can take several hours or more.
Caution: Do not use any heat-generating equipment, such as hair dryers or heat guns. Inside your freezer, there are numerous plastic components, such as the compartment walls and the fan blades, that should be avoided. Using a concentrated burst of heat could cause them to warp or melt, resulting in even more damage.
2. Faulty Freezer Fan Motor
When the fan blades turn in order to force cold air throughout the freezer compartment, as previously stated, the following occurs: A motor connected to the fridge’s main control board is responsible for turning those fan blades.
Whenever the freezer isn’t cold enough, the fan motor will be powered up and given the go-ahead to start working.
Once the freezer has reached the desired temperature, the motor will shut off.
When it fails, it can be caused by the freezer fan motor overheating and burning out after prolonged use. This is especially true if there was an ice buildup around the fan blades, as described in the preceding section of this article.
For example, ice buildups on the fan blades will prevent the blades from turning smoothly. As a result, the fan motor has to work harder in order to turn the blades of the fan. At some point, the motor will overwork itself and burn itself out, rendering it incapable of performing any function.
It is necessary to replace the freezer fan motor if it is malfunctioning. In order to avoid injury and electrocution, turn off all power to the Samsung refrigerator before beginning the process.
After that, you’ll need to empty your freezer. That means you’ll have to remove all of the food items from the refrigerator and dismantle the shelves inside.
After removing all of the items from the way, you will be able to reach the back panel. After that, gently remove the panel by unthreading the screws that are holding it in place. Be careful not to damage the wires as you do so.
After that, disconnect all of the electrical connectors and remove the panel. There are mounting screws attached to the freezer evaporator fan panel, so you’ll need to unthread them in order to remove the fan from the freezer.
After that, install the new fan in the same location as the old one and replace the mounting screws.
3. Malfunction of the Main Control Board
Exactly what it is: This is a critical component of your Samsung refrigerator that serves as the appliance’s “brain.” The board in question is a printed circuit board (PCB), which has numerous small components attached to it. Each of those components is in charge of a particular function or component of the refrigerator as a whole.
One or more of those components is intended to supply power and signals to the freezer evaporator fan, ensuring, in particular, that it turns on and off when necessary.
Electrical damage can occur to the components on the main control board, which is the cause of the failure. If a short circuit occurs in some parts of the control board, such as the ones responsible for controlling the freezer evaporator fan, the control board may be damaged as a result.
When this occurs, your Samsung refrigerator will be unable to send or receive any signals from the fan, resulting in the 88 8a error code being displayed on the screen.
Attempting to repair it will not work because the main control board, even if only a section of it has failed, is not repairable. Instead, you’ll be required to replace the entire control board with new components. Fortunately, on Samsung refrigerators, this is a simple process.
As is customary, begin by unplugging the refrigerator from its power source.
In the back of the refrigerator, behind an access panel, is a board that contains important information. Take off the panel and you’ll be able to see the board with a lot of wiring attached to it. Unthread the screws holding the panel together.
Take a photo of the area before you begin removing anything so you can refer to it later. After that, disconnect the connectors and detach the board from the clips that are holding it in place.
Install the new board in its proper location and connect the wire harnesses in the same manner as the previous one.
Last but not least, the access panel that conceals the main control board should be replaced.
How Do You Reset Your Samsung Refrigerator?
It will take you no more than five minutes to reset your Samsung refrigerator. To accomplish this, follow these steps:
- To begin, remove the power plug from the wall socket that is connected to your refrigerator.
- After that, turn off the refrigerator for at least five minutes to allow it to clear its memory.
- Finally, turn on the refrigerator once more.
- “Power cycling” is the term used to describe the process of turning on and off various electronic devices, including your Samsung refrigerator.
How Do You Test Your Samsung Fridge After It Has Been Repaired?
After you’ve repaired your refrigerator and removed the 88 8a error code from its display, you must allow your refrigerator at least 24 hours to stabilize its temperature before continuing.
Do not be concerned if the freezer is still a little warm after the repair has been completed.
In addition, you can consider the next 24 hours to be your testing period. It is presumed that the repairs were successful if no other error codes appear during this time period.
Our Final Thoughts
The central board of the refrigerator may be faulty if the error code 88 in the Samsung refrigerator appears again after all of the necessary actions have been taken. If there is an unexpected power outage, excessive peak currents, or if there is a short circuit in the network, it could be severely damaged or even destroyed.
Frequently Ask Questions
What does the code on a Samsung refrigerator mean exactly?
This code indicates that the refrigerator is in Display Mode, Demo Mode, or Showroom Mode, depending on the model of the Samsung refrigerator. They are intended for displaying the appliance in a store or showroom, such as the showroom floor at Home Depot, Lowe’s, Best Buy, and other similar establishments.
What is the procedure for resetting a Samsung 88 88 refrigerator?
If this is the case, simply hold down the power save and lighting buttons for 10 seconds, and the error will be resolved automatically. Either that or simultaneously press the fridge and freezer buttons for 10 seconds to reset the control panel and clear the error code.
What does the 5c symbol on my Samsung refrigerator mean?
It indicates that the defrost sensor is malfunctioning. A switch is provided between the timer and the heater by this component of the system. When the temperature reaches a certain point, the contacts of the heater close and the heater transmits voltage through the contacts of the heater. The contacts are then opened, the heater is turned off, and the timer begins the defrost countdown.
