Samsung Refrigerator Error Code Ice Maker Sensor Error (Cubed Ice)

This error means the temperature sensor for the cubed ice maker has reported a reading above 65°C or below -50°C, which falls outside the valid operating range. The refrigerator interprets this as a sensor separation, connection failure, wiring break, or internal short circuit. The ice maker will typically stop operating until the fault is resolved. Diagnosis starts by measuring the voltage at main PCB connector CN90 pins 11 through 13, which should read between 1.0V and 4.5V under normal conditions.

The refrigerator's cooling and food preservation functions are separate from the ice maker circuit, so food stored in the refrigerator and freezer compartments should remain safe. However, the cubed ice maker will likely not operate correctly while this error is active. It is best to resolve the fault promptly to avoid any secondary issues with the ice maker assembly.

If the fix is a simple connector reseating, there may be no parts cost at all, only a service call fee if a technician is involved. Replacing the ice maker temperature sensor typically costs between $20 and $80 for the part alone, with professional labor adding $100 to $250 depending on your location and the service provider. If the main PCB requires replacement, total repair costs can range from $200 to $500 or more, which may make comparing repair cost to appliance age worthwhile.

A knowledgeable DIYer can perform initial checks such as inspecting the sensor connector for loose or corroded contacts and verifying the sensor has not separated from its mounting bracket inside the ice maker. If the connector appears secure and the sensor is properly positioned, further diagnosis requires a multimeter to check voltage at the main PCB and resistance at the sensor itself. Replacing the sensor is a moderate-difficulty repair, but if the main PCB is implicated, professional service is recommended.

A power reset may temporarily clear the error code from the display, but if the underlying fault with the sensor, wiring, or connector still exists, the error will return once the refrigerator restarts and the control board reads the sensor again. A reset alone is not a repair. The sensor circuit needs to be inspected and the fault corrected for the error to clear permanently.
