Samsung fridge error codes are messages generated by the refrigerator’s diagnostic system. They may identify a fan problem, voltage interruption, communication fault, water issue or operating mode.
Not every message means that a component has failed. Some displays appear during Wi-Fi setup, software updates, startup checks or Cooling Off Mode. The first step is to photograph the complete display before pressing buttons or disconnecting power.
Do not reset the refrigerator immediately
Clearing the display can remove information needed for diagnosis. Unless the instructions for the displayed code specifically recommend a power cycle, leave the code visible, record it and check the exact model manual.
Find the Code by Type
Status and Setup Messages
AP
Access Point Mode
AP appears while the refrigerator is connecting to Wi-Fi or being configured through SmartThings.
It should disappear after setup finishes or the connection process times out. It does not normally indicate a cooling failure.
All icons flashing
Refrigerator Self-Diagnostic Check
All display icons may flash during the normal startup process after the refrigerator is connected to power or after a power interruption.
Wait several moments for the check to finish. Record the display if the flashing continues or another code appears afterward.
OF OF, O FF or OFF OFF
Cooling Off or Demo Mode
The refrigerator lights and display remain active, but the cooling system is disabled. This mode is commonly used for showroom displays.
On control panels covered by Samsung’s current instructions, hold the top two buttons on the left side for approximately five to eight seconds until a chime sounds.
Because control layouts vary, confirm the correct procedure in the manual before pressing a button combination.
Cooling and Fan Codes
CODE 21E
Freezer Fan Error
The freezer fan is not operating as expected. The fan may be blocked by frost, the motor may have failed or the freezer door may have remained open.
Check safely
- Make sure the freezer door closes completely.
- Move packages away from internal vents.
- Look for heavy frost near the rear freezer panel.
Defrost the appliance according to its model instructions. Do not chip ice with a knife or use a heat gun. Arrange service if the code returns.
CODES 22E OR 22C
Refrigerator Compartment Fan Error
These codes relate to the fan that moves cold air through the fresh-food compartment. Frost, a blocked air passage, an open door or a damaged fan may be involved.
Check safely
- Make sure containers are not covering air vents.
- Check that the door closes and seals evenly.
- Listen for scraping or grinding behind the interior panel.
Samsung’s current guidance recommends unplugging the refrigerator for several hours with the doors open, then restarting it.
Move perishable food to safe cold storage before defrosting. Request service if the code or fan noise returns.
Fan errors can cause uneven temperatures even when part of the refrigerator still feels cold. Review the guide for a refrigerator that is not cold enough when food temperatures are rising.
Power, Software and Communication Codes
41 or 42 With Flashing Blue Lights
These messages relate to a Family Hub software or system problem. Compatible models can be rebooted using the Family Hub power switch inside the top portion of the right door.
Use the model manual to identify the correct switch. Arrange service when the display continues to restart or the error returns.
41C
This code indicates a Family Hub software-update issue. Select OK once when prompted and verify that the latest software update has completed.
Repeatedly rebooting the refrigerator is unlikely to correct an update fault that keeps returning.
85C
85C is a low-voltage notification that can appear after a brief voltage drop. Samsung describes the one-time notification as harmless.
Hold OK for approximately three seconds to clear it when that action applies to the model. Do not confuse 85C with the separate 85E voltage-error code.
88 88, 83E, 85E OR 86E
Power or Voltage Error
These messages can follow a power surge, brownout, voltage problem, abnormal compressor current or communication interruption.
Turn off refrigerator power or unplug it for approximately one minute, then restore power. Request service when the same code returns.
PC ER or PC CH
The refrigerator has detected a communication problem. A power surge or loose connection near a door hinge may be involved.
Samsung’s instructions refer to reconnecting the wire harness above the door. Because hinge covers and wiring differ by model, avoid pulling apart connectors unless the owner’s manual provides a clear owner-safe procedure. Professional service is appropriate when the connection is not readily accessible.
Water and Ice Messages
76C or Flashing Autofill Indicator
Water or moisture has been detected in the Autofill compartment.
Remove the pitcher, dry the compartment and reinstall it correctly. Arrange service if water returns or there is an active leak.
Ice Off Indicator Blinking
The ice bucket may be missing or incorrectly seated.
Remove and reinstall the bucket according to the model instructions. Check for frozen cubes or packaging that prevents it from locking into position.
Codes Not Included in Samsung’s Current Quick Guide
Codes such as 1E, 5E, SE, 23E, 24E, 25E, 26E and 40E appear in older articles, service references and discussions about particular refrigerator models.
That does not mean each code has the same meaning across every Samsung refrigerator. Segmented displays can also make a number resemble a letter.
Confirm these codes using the complete model number and model-specific documentation. Do not purchase a fan, heater, valve, sensor or control board based only on a general online list.
Reset or Leave the Code Visible?
Leave it visible
The code is unknown, cooling is affected, the refrigerator is making a new noise or the official instructions do not mention a reset.
Use the code-specific action
Samsung provides a clear instruction, such as drying the Autofill compartment, seating the ice bucket or completing a one-minute power cycle for listed voltage errors.
Book service
The same code returns, temperatures continue rising, a fan scrapes, water leaks or the recommended action requires access to internal wiring or components.
Information to Record Before Calling
- The complete error code and flashing icons
- The refrigerator model number
- When the code first appeared
- Whether it followed a power outage or refrigerator move
- Current refrigerator and freezer temperatures
- Any frost, water, fan noise or door problem
- The troubleshooting step already attempted

Error meanings and button procedures can change between models. Compare the display with Samsung Canada’s current refrigerator guide and the manual for the exact model.
Samsung Fridge Error Code Questions
Should I unplug my Samsung fridge when a code appears?
Not unless the instructions for that code recommend it. Photograph the display first because clearing it can make the original problem harder to diagnose.
What does OF OF mean on a Samsung refrigerator?
OF OF means Cooling Off or Demo Mode is active. The display and lights work, but the refrigeration system is disabled.
Why does a Samsung fan code return after defrosting?
Returning fan errors can indicate a failed fan motor, sensor, defrost component, wiring issue or recurring air leak rather than temporary ice alone.
When does a Samsung fridge code need professional repair?
Arrange service when the code returns after the approved action, the appliance is not cooling, a fan is scraping, water is leaking or the repair requires access to internal electrical parts.
Code Still Showing After the Recommended Step?
A recurring code may require testing of the fan, sensor, wiring, water system, power supply or electronic control rather than another reset.
