Samsung Fridge Error Codes - Complete Guide to Meanings, Resets & Common Faults
A Samsung fridge error code is a diagnostic message generated when the refrigerator detects an unusual condition involving a sensor, fan, defrost system, ice maker, compressor circuit, communication network, power supply or another monitored function.
The important point is that an error code identifies an area that needs attention. It does not always identify the exact failed part.
For example, a fan error may result from a failed fan motor, but it can also appear when ice prevents the fan from turning. A sensor-related code might involve the sensor itself, its wiring, a connector or the electronic control receiving the signal.
Samsung refrigerator codes also vary between models, product generations and markets. A code found online should therefore be checked against the exact refrigerator model before parts are replaced or internal repairs are attempted. Samsung Australia itself notes that models, sequences, settings and error codes can vary according to where a product was sold.
This guide explains commonly documented Samsung fridge error codes, what they can indicate, what you can safely check yourself and when further diagnosis is sensible.
Samsung Fridge Error Codes Quick Reference
The following table covers commonly documented Samsung refrigerator codes and status messages. Some apply only to particular models or refrigerator families.

Samsung currently documents these as commonly encountered codes and messages, but also stresses that the list is not exhaustive.
Before You Reset a Samsung Fridge, Record the Error Code
It is tempting to unplug the refrigerator as soon as an error appears.
That is not always the best first step.
Samsung specifically advises against automatically disconnecting the refrigerator or pressing controls simply to make an error disappear, because doing so can remove information that may help with diagnosis.
Before attempting a reset:
- Take a clear photo of the display.
- Write down the complete code.
- Record whether the fridge, freezer or both are warming.
- Note any unusual sounds, frost, water leaks or ice-maker problems.
- Find the refrigerator model number.
- Think about what happened immediately before the code appeared, such as a power outage, door removal, water-filter change or extended period with a door open.
If the refrigerator later needs professional diagnosis, this information can be far more useful than simply saying that an error appeared and was reset.
Common Samsung Error Codes Explained
What Does Samsung Error Code 5E Mean?
Samsung documents 5E as a fridge defrost sensor error on relevant refrigerator models.
The defrost system helps control frost around the evaporator. If the refrigerator cannot correctly monitor defrost temperature, frost may eventually interfere with normal airflow.
A 5E code does not necessarily prove that the sensor itself is physically broken.
Diagnosis may involve checking:
- the defrost sensor
- sensor wiring
- electrical connections
- evaporator icing
- defrost heater operation
- the relevant control circuit
If frost continues building after being cleared, the underlying reason should be investigated rather than repeatedly defrosting the refrigerator.
Samsung 21E: Freezer Fan Error
21E means the refrigerator is not detecting the expected freezer fan rotation.
Samsung says the fan may be frozen by ice, obstructed because of conditions caused by an open door or poor door seal, or the fan motor itself may have failed.
The evaporator fan is important because it moves cold air through the freezer and, depending on the refrigerator design, contributes to temperature distribution elsewhere in the appliance.
Possible causes include:
- ice preventing the fan blade from turning
- freezer door not sealing
- excessive frost around the evaporator
- failed fan motor
- wiring or connector problem
- defrost fault causing recurrent icing
If the code disappears after the refrigerator is fully defrosted but later returns, that can indicate that the fan obstruction was a symptom of a continuing frost or defrost problem.
Simply replacing the fan would not necessarily correct that underlying cause.
Samsung 22E or 22C: Fridge Fan Error
22E or 22C generally indicates a refrigerator compartment fan error.
Samsung notes that this may occur if the door has been left open long enough for conditions around the evaporator or fan to change. If the fault returns after the appliance has been allowed to defrost and return to normal operation, service may be required.
A technician may need to consider:
- evaporator fan operation
- ice around the fan
- frost accumulation
- door gasket condition
- defrost performance
- fan wiring
- electronic control
One useful clue is noise. If you hear scraping, rattling or a repetitive fan sound before the error appears, ice may be contacting the fan blade or the fan motor may be deteriorating.
Samsung 84C: Compressor Lock
Samsung lists 84C as a compressor lock error.
A compressor is the component that circulates refrigerant through the sealed refrigeration system.
However, a compressor-related error still needs proper electrical and refrigeration diagnosis.
The technician may need to assess:
- whether the compressor is attempting to start
- compressor current
- inverter or control output where applicable
- electrical connections
- compressor condition
- refrigeration-system pressures and performance
A refrigerator that is warm is not enough evidence on its own to condemn the compressor.
Samsung Ice Maker Error Codes
Samsung refrigerators with automatic ice systems can monitor several different parts of the ice-making process.
Because ice makers rely on freezer temperature, water supply, sensors, heaters, fans and electronic control, an ice-maker code should not automatically be interpreted as a failed ice-maker assembly.
Samsung 8E
Samsung lists 8E as an ice maker/freezer sensor error on applicable models.
This points towards the sensing side of the ice-making system rather than automatically proving a mechanical jam.
Samsung 14E
14E is another documented ice-maker sensor error.
The exact sensor location and test procedure depend on the refrigerator.
Samsung 33E
Samsung identifies 33E as an ice pipe heater error.
Heaters may be used around particular sections of the ice or water system to control freezing conditions. Internal electrical testing is usually needed if this code persists.
Samsung 39E or 39C
39E and 39C indicate an ice maker function error on applicable Samsung refrigerators.
The code is broader than simply saying that the ice maker motor has failed.
Possible diagnostic areas can include:
- ice maker mechanism
- freezer temperature
- sensing
- wiring
- water supply
- control functions
- ice obstruction
If the freezer itself is not cold enough, the ice maker may stop producing ice even though the original fault lies elsewhere in the refrigeration system.
Samsung 40E or 40C
Samsung describes 40E or 40C as an ice-room fan error.
Where a refrigerator uses a dedicated ice compartment, airflow can be important to maintaining the required temperature.
The problem could involve the fan itself or conditions preventing normal fan movement.
Samsung 83E, 85E and 86E: Compressor and Power Errors
These three codes are often grouped together online simply as "power errors", but Samsung provides more specific meanings.
83E: Compressor Abnormal Current
Samsung states that 83E means abnormal current to the compressor has been detected. A power surge or other electrical disturbance may be associated with the event.
This does not automatically mean the compressor must be replaced.
Proper diagnosis may require checking:
- incoming power conditions
- compressor electrical behaviour
- control/inverter circuitry
- compressor operation
- related wiring
85E: Compressor Under-Voltage
85E indicates a compressor under-voltage condition.
Samsung notes that a brownout or other low-voltage event may be involved.
86E: Compressor Over-Voltage
86E indicates compressor over-voltage.
A surge or electrical event may be the trigger.
For these specific voltage-related codes, Samsung does recommend disconnecting the refrigerator or switching off the circuit breaker briefly before restoring power. If the code returns, further diagnosis is recommended.
That is different from blindly resetting every error code.
Samsung 88 88 Error Code
Samsung identifies 88 88 as a communication fault that can appear when power is disrupted during refrigerator startup.
This is one of the situations where a controlled power reset may be appropriate.
If the code clears and normal cooling returns, continue monitoring the appliance.
If it repeatedly comes back, particularly when there are no new power interruptions, further electrical or communication diagnosis may be required.
PC ER or PC CH: Samsung Fridge Communication Error
PC ER and PC CH indicate a communication problem between electronic components in the refrigerator.
Samsung notes that these errors may appear after a power surge or when door-related wiring is not correctly connected.
This is especially relevant after:
- refrigerator delivery
- door removal
- hinge work
- door replacement
- wiring disconnection
- a significant electrical event
Modern refrigerator doors can contain display, sensor, water, ice or communication wiring depending on the model.
Previous door work does not prove that wiring caused the error, but it is useful information to mention when arranging diagnosis.
Avoid dismantling hinge covers or electrical connectors unless you are qualified and have the correct model-specific information.
What Does OF OF Mean on a Samsung Fridge?
If a Samsung fridge displays:
- OF OF
- O FF
- OFF OFF
- or scrolling temperature bars
the refrigerator may be in Cooling Off Mode, also called Demo Mode or Shop Mode.
This is not necessarily a refrigeration failure.
In Cooling Off Mode, the refrigerator's cooling functions are deliberately disabled so the appliance can be displayed in a showroom while lights and controls continue operating.
That creates a confusing symptom: the fridge appears powered on, but it does not get cold.
The correct button sequence for leaving Demo Mode varies between Samsung models. Check the instructions for your particular refrigerator rather than trying random button combinations.
Samsung AP Code
AP means Access Point mode.
The refrigerator is temporarily acting as an access point while being configured for Wi-Fi or SmartThings.
It is generally a setup status rather than a refrigeration fault and should disappear after configuration is finished or times out.
Samsung Family Hub Error Codes
Family Hub refrigerators contain additional display, software and connected functions, so some messages relate to the smart interface rather than the refrigeration circuit.
41 or 42 With Blue Lights Flashing
Samsung associates these displays with a Family Hub software or system issue.
41C
41C can appear following a Family Hub software update on applicable three-door French Door models.
Samsung recommends confirming that the latest update is installed and following the model-specific on-screen instructions. Repeated occurrences may require further support.
76C
76C means water has been detected in the Autofill compartment on applicable refrigerators.
Drying the affected area may resolve the message, but repeated water detection could justify checking for the source of moisture.
85C
On applicable Family Hub models, 85C is a low-voltage warning that may follow a brief power interruption.
Samsung describes this particular warning as harmless and gives a model-specific clearing procedure.
What Do C6 and C13 Mean on a Samsung Fridge?
C6 and C13 are a good example of why Samsung refrigerator codes need to be interpreted by model rather than from one universal online chart.
Owners of Samsung RF28T5001SR refrigerators have reported C6 and C13 appearing together or intermittently, sometimes after a power outage. In community discussions, model-specific service information has been referenced identifying C6 with an external or ambient-air sensor, while humidity sensing and related wiring have also featured heavily in C13 investigations.
Samsung's own older technical support material identifies 13E/13C as a humidity sensor error on applicable refrigerator models.
The practical lesson is more important than memorising a code:
If C6 or C13 appears, record the exact model number.
Depending on the refrigerator, diagnosis may involve:
- ambient or external temperature sensing
- humidity sensing
- wiring harnesses
- electrical connectors
- PCB inputs
- previous door or hinge work
Do not order a sensor solely because another owner with a different Samsung refrigerator used the same-looking code.
Older and Model-Specific Samsung Sensor Codes
Some Samsung service documentation uses additional sensor codes that may not appear in Samsung's current consumer-facing error-code guide.
Examples found in particular refrigerator service documentation include:
- 2E for a refrigerator compartment sensor fault
- 4E for a freezer defrost sensor fault
- 6E for an ambient or environmental temperature sensor fault
- 13E for a humidity sensor fault
These should be treated as model-specific codes, not universal definitions across every Samsung fridge.
That distinction is important because Samsung itself states that error codes vary between models and markets.
If your display shows one of these codes, identify the model before using an online error-code chart.
Why Is My Samsung Fridge Display Blinking?
A blinking display does not always mean the same thing as a fault code.
There are several different situations to distinguish.
Temperature Display Blinking
Some Samsung refrigerators blink the temperature display when the internal temperature becomes unusually high.
Samsung's current guidance for relevant models notes that the display can blink when the refrigerator temperature rises above its warning threshold, including after a door has been left open or following a power interruption.
If the refrigerator is recovering normally, the display may stop blinking after cabinet temperature falls again. If the fridge remains warm, investigate the cooling problem rather than focusing only on the blinking display.
All Icons Flashing
Samsung says that all display icons briefly flashing after the fridge is connected to power or following an outage can simply be the refrigerator running its normal self-diagnostic process.
Ice Off Indicator Flashing
A flashing Ice Off indicator can mean that the ice bucket is missing or incorrectly positioned.
Random Display Segments Blinking
Older Samsung models or refrigerators without a conventional numeric display may show error information through particular illuminated display segments.
Take a photo before changing anything. The pattern may contain useful diagnostic information.
Samsung Fridge Error After a Power Outage
Power interruptions are a recurring theme in both Samsung documentation and real-world owner reports.
After power returns, you may see:
- flashing icons
- temperature warnings
- 88 88
- 83E
- 85E
- 86E
- 85C on applicable Family Hub models
- other model-specific codes
Samsung confirms that several voltage and communication codes can follow surges, brownouts or interrupted startup.
Reddit discussions also show owners reporting C6/C13 and other unusual displays immediately after power interruptions, reinforcing the importance of noting when the error began rather than interpreting the code in isolation.
If the fridge returns to its normal operating temperature and the warning does not reappear, continue monitoring it.
If the error returns or cooling remains poor, the power event may simply have exposed an existing sensor, communication, electrical or refrigeration problem.
Samsung Fridge Error After Door Removal or Replacement
This is another detail worth mentioning when booking a repair.
On many modern Samsung refrigerators, door areas can contain:
- sensor wiring
- display wiring
- communication harnesses
- water lines
- ice-system connections
Samsung specifically lists improper door connections as one possible cause of PC ER or PC CH communication errors.
Real-world discussions involving Samsung RF28T-series refrigerators have also raised wiring and sensing concerns following previous door replacement or installation work.
If an error first appeared after:
- moving the refrigerator
- removing a door
- replacing a door
- hinge repairs
- installation work
tell the technician. That history can guide the diagnostic process.
How to Clear Samsung Fridge Error Codes Safely
There is no single reset procedure that should be applied to every Samsung refrigerator error.
A better sequence is:
-
Photograph the Code
Do this before switching anything off. -
Check the Model Number
Samsung refrigerator controls and diagnostic procedures differ between product families. -
Check the Fridge Temperature
An error is more urgent when cooling performance is also deteriorating. Samsung Australia recommends approximately 3°C for the refrigerator and -19°C for the freezer on applicable models. -
Perform Simple External Checks
Depending on the problem, check:- doors are fully closed
- nothing is blocking the door
- visible gaskets are clean
- air vents are not obstructed by food
- the refrigerator has power
- water supply is on if the problem concerns an ice maker or dispenser
- ice bucket is correctly fitted where relevant
-
Follow Reset Instructions Only When Appropriate
Samsung explicitly recommends a power reset for certain voltage and communication errors, but not as the default response to every code. -
Check Whether the Code Returns
A code that disappears permanently after a documented reset is different from one that returns immediately. A recurring code usually deserves further investigation.
Why Does the Samsung Error Code Return After a Reset?
Because resetting the control does not repair a physical fault.
If a code is caused by:
- a failed sensor
- damaged wiring
- loose connector
- frozen fan
- defective fan motor
- defrost problem
- communication fault
- compressor problem
- water-system issue
the refrigerator may detect the same condition again as soon as it resumes normal operation.
Think of the reset as restarting the monitoring system.
It may clear a temporary electronic condition, but it cannot repair damaged hardware.
This is why repeated resets can become counterproductive. They may make the display temporarily look normal without correcting the underlying reason the code appeared.
How to Find Your Samsung Fridge Model Number
The model number matters because Samsung error codes, button sequences and diagnostic procedures vary between refrigerator families.
Samsung Australia says refrigerator model and serial information can generally be found:
- on a label near the lower left exterior of the refrigerator
- or on another label inside the refrigerator compartment, usually on a side wall above the upper shelf
The exact label position can vary with French Door, Side-by-Side, Top Mount and Bottom Mount designs.
A model might look similar to: RF28T5001SR/AA or use a different Samsung model format depending on the market.
When arranging a repair, provide the full model code if possible, including letters and suffixes.
Safety, Usage & Diagnostics FAQ
Is a Samsung Fridge Error Code Dangerous?
Not every Samsung error code represents an immediate safety problem.
AP mode, Cooling Off Mode, a Family Hub software message or a briefly flashing self-diagnostic display can have very different implications from a fridge that is warming while showing a fan or compressor error.
The most important practical question is: Is the refrigerator still keeping food cold?
For Australian households, the NSW Food Authority recommends keeping a home refrigerator below 5°C and a freezer at -18°C or colder.
If your fridge temperature is rising above safe storage levels, treat the cooling failure as the priority rather than spending hours trying to clear the display.
A fridge thermometer can help confirm actual cabinet temperature.
Can I Keep Using a Samsung Fridge With an Error Code?
It depends on the code and the refrigerator's actual performance.
You may be able to continue monitoring the fridge if:
- the message is a known status indicator
- normal cooling is confirmed
- there are no unusual sounds or leaks
- the code clears according to the model's documented instructions
Arrange further diagnosis if:
- refrigerator temperature is rising
- frozen food is softening
- the fan is scraping or repeatedly stopping
- heavy frost keeps returning
- water is leaking
- the error immediately returns after the recommended procedure
- the compressor repeatedly attempts to start
- the fridge has stopped cooling entirely
- multiple codes appear together
- the same fault has occurred several times
Food Standards Australia New Zealand advises keeping potentially hazardous refrigerated food at 5°C or colder.
Does an Error Code Tell You Which Part to Replace?
Usually not with enough certainty to skip diagnosis.
Consider 21E. The system is reporting a freezer fan problem, but possible reasons include:
- ice obstruction → fan cannot rotate
- or: fan motor failure → fan cannot rotate
- or: wiring problem → fan feedback is not received
- or: defrost failure → ice develops → fan eventually becomes blocked
Those situations can produce a similar code but require different repairs.
The same principle applies to sensors.
A sensor error can involve: sensor → wiring → connector → PCB input rather than automatically meaning: replace sensor.
This is why professional refrigerator diagnosis should follow the circuit and symptoms rather than treating the error-code description as the final answer.
When Should You Book Samsung Fridge Repairs?
A Samsung error code is worth professional diagnosis when the refrigerator is no longer maintaining temperature, the code returns repeatedly or the fault involves internal electrical or refrigeration components.
Common situations include:
- 21E or 22E repeatedly returning
- persistent defrost sensor errors
- ice maker codes that continue after basic checks
- PC ER or PC CH communication errors
- compressor-related codes
- repeated voltage codes without an obvious temporary power event
- C6/C13 or other model-specific sensor codes accompanied by poor cooling
- refrigerator and freezer temperatures both rising
- unusual compressor behaviour
- recurring heavy frost
- fan obstruction that keeps returning
- error code plus water leakage
- multiple simultaneous faults
If you are in Sydney and a code is accompanied by a refrigeration problem, our Samsung Fridge Repairs Sydney service covers Samsung fridges and freezers with diagnosis based on the actual symptoms, model and components involved.
That means the error code becomes the starting point for testing rather than a reason to guess which part needs replacement.
What Information Should You Give the Fridge Technician?
Before calling, gather as much of the following as you can:
- Samsung model number
- complete error code
- photo of the display
- current refrigerator temperature
- current freezer temperature
- whether both compartments are affected
- unusual sounds
- visible frost
- water leakage
- ice-maker behaviour
- recent power outage
- recent door replacement or removal
- previous repair history
For example:
"Samsung RF28T5001SR showing C6 and C13 after a power interruption. Fridge is warmer than normal but freezer is still partly cooling."
That gives much more diagnostic information than: "Samsung fridge has an error."
Samsung Fridge Error Codes: Final Takeaway
Samsung refrigerator error codes are useful because they narrow the area that needs investigation, but they should not be treated as universal part-replacement instructions.
Remember these five points:
- Record the code before resetting the fridge.
- Check the exact Samsung model number.
- Treat actual temperature and cooling performance as seriously as the display message.
- Remember that a code identifies a system or condition, not always the failed component.
- If the error returns, diagnose the reason rather than repeatedly clearing the display.
Codes involving fans, sensors, ice makers, communication, defrost systems, voltage and compressor operation can often share symptoms with other faults. Proper diagnosis looks at the error code together with the refrigerator's temperature, airflow, recent history and electrical or refrigeration performance.
