Samsung BESPOKE Refrigerator Error Codes: Complete List

Samsung BESPOKE refrigerators use diagnostic error codes to help identify faults affecting temperature sensors, fans, defrost systems, ice makers, compressor operation, and electronic communication.

This guide lists Samsung BESPOKE refrigerator error codes by category, including sensor errors, functional faults, communication errors, and other system alerts.

1. Samsung BESPOKE Refrigerator Sensor Error Codes

Sensor error codes indicate that a temperature sensor or another sensing component may be reporting an abnormal value. For many temperature sensors, an error can occur when the measured temperature reaches +50°C or higher or −50°C or lower. Possible causes include a disconnected sensor, poor electrical contact, damaged wiring, an open circuit, or a short circuit.

The interior and exterior plate temperature sensors have different specified thresholds, as listed below.

Error Code	Description
1C	Freezer temperature sensor error
2C	Refrigerator compartment first temperature sensor error
3C	Refrigerator compartment second temperature sensor error
4C	Freezer defrost sensor error
5C	Refrigerator defrost sensor error
6C	Ambient temperature sensor error
7C	Fresh compartment temperature sensor error
8C	Freezer ice maker sensor error (cubed ice)
9C	CV compartment temperature sensor error
11C	CV compartment defrost sensor error
13C	Humidity sensor error
110C	Interior plate temperature sensor error: triggered at +95°C or higher or −25°C or lower
111C	Exterior plate temperature sensor error: triggered at +95°C or higher or −25°C or lower
116C	Ice Bites/Whiskey ice maker sensor error

Troubleshooting tip: Inspect the sensor connector and wiring harness first. If the connections are secure, check the sensor resistance against the specifications in the model-specific service manual. Do not replace a sensor based on the code alone.

2. Samsung BESPOKE Refrigerator Function Error Codes

Function error codes identify problems involving fans, defrost heaters, ice makers, dampers, the compressor, specialized cooling systems, and other operating components.

Fan, Defrost, Heater, and Ice Maker Errors

Error Code	Description
21C	Freezer compartment fan error
22C	Refrigerator compartment fan error
23C	C-fan error
24C	Freezer defrosting error: defrosting does not complete within 120 minutes of continuous heating.
26C	Freezer ice maker function error (cubed ice); displayed after more than three ice maker errors
27C	Damper heater error
28C	Deodorizer fan error
31C	CV compartment fan error
32C	CR fan error
33C	Freezer ice pipe heater error
34C	Water tank heater error
62C	Fresh compartment fan error
63C	Freezer damper heater error
76C	AutoFill Infuser overflow error
98C	DOC 1 motor function error
99C	DOC 2 motor function error
117C	Ice Bites/Whiskey Ball ice maker function error; displayed after more than three ice maker errors
118C	Ice Bites/Whiskey Ball ice pipe heater error
127C	Beverage Zone (Specialization Zone) fan error
154C	Peltier cooling fan error (inside the refrigerator)
155C	Peltier heat-dissipation fan error (outside the refrigerator)
156C	Peltier fan error persisting for 24 hours

Possible causes include a defective motor, disconnected wiring, poor connector contact, an open or shorted heater circuit, or a faulty feedback signal. For overflow-related faults, inspect the water system and relevant sensor connections according to the service procedure.

Temperature and Cooling System Errors

Error Code	Description
71C	Freezer compartment high-temperature error
72C	Refrigerator compartment high-temperature error
73C	CV compartment high-temperature error
81C	Compressor operation or startup failure
82C	Compressor IPM fault (gate driver fault)
83C	Compressor abnormal current or position detection error
84C	Compressor motor error or motor constraint fault
85C	Compressor low-voltage error; AC input voltage is 53 V or lower.
86C	Compressor high-voltage error; AC input voltage is 154 V or higher.
96C	Compressor IPM shutdown error
113C	Peltier module error
130C	Compressor DC-link voltage sensor error
131C	Compressor phase-current sensor error
132C	Compressor IPM temperature sensor error
133C	Compressor overload error
153C	Peltier module error persisting for 24 hours

High-temperature codes may occur when the compartment temperature rises abnormally or a door remains open for a specified period. Compressor-related codes can indicate problems with the inverter drive, electrical supply, current sensing, motor operation, or compressor protection system.

Troubleshooting tip: Before diagnosing a compressor fault, verify the power supply and inspect the relevant wiring and connectors. Compressor inverter circuits can contain hazardous voltages. Electrical testing and inverter diagnosis should be performed by a qualified technician using the manufacturer’s procedures.

3. Samsung BESPOKE Refrigerator Communication Error Codes

Communication errors indicate that electronic control boards or connected modules are not exchanging data correctly.

Error Code	Description
41C	Communication error between the main board and display panel board
42C	Communication error between the main board and load board
44C	Communication error between the main control board and compressor inverter
46E	I/O expander communication error with the main controller
52C	Communication error between the main controller and Wi-Fi module
53C	Inverter AI streaming communication error between the inverter AI CPU and main controller
54C	Inverter background OTN communication error between the inverter AI CPU and main controller

Possible causes include loose connectors, damaged communication wiring, power-supply problems, or a faulty electronic module. Codes 53C and 54C are described in the technical materials as temporary communication abnormalities that may recover when the compressor is turned off.

Troubleshooting tip: Inspect connectors and wiring before replacing a control board. Follow the model-specific service procedure to determine whether the fault is caused by the wiring, the connected module, or the main controller.

4. Other Samsung BESPOKE Refrigerator Error Codes

These codes relate to proximity sensors and the Easy Open door-opening system.

Error Code	Description
A3C	Mid-left proximity sensor error
67C	Easy Open #1 error (right AOD motion system)
68C	Easy Open #2 error (left AOD motion system)

Inspect the relevant sensor, actuator, wiring, and mechanical movement according to the refrigerator’s service documentation.

General Troubleshooting Recommendations

When a Samsung BESPOKE refrigerator displays an error code, follow these general diagnostic steps:

1. Record the error code. Note the exact code and any symptoms, such as insufficient cooling, fan noise, ice maker failure, or a door that does not open correctly.
2. Check basic operating conditions. Confirm that the refrigerator has a reliable power supply and that the doors close properly.
3. Inspect accessible connections. With the appliance safely disconnected from power, check accessible wiring harnesses and connectors for looseness or visible damage.
4. Consult the correct service manual. Component locations, test procedures, and error-code meanings can vary by model.
5. Test before replacing parts. Use the manufacturer’s diagnostic procedures and component specifications to confirm the underlying fault.

Do not repeatedly reset the refrigerator or replace parts without identifying the cause. Compressor inverter circuits, electrical heaters, and internal control boards may present electrical hazards.
