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

This error means the temperature sensor inside the Ice Bites ice maker assembly has failed or lost its connection to the main control board. The board expects a voltage between 1.0V and 4.5V at connector CN90, and when that signal is missing or out of range, it logs this fault. The sensor may have separated from its mount, developed a short circuit, or lost continuity through the wiring harness. The ice maker will stop producing ice until the fault is corrected.

The refrigerator's cooling and freezing functions are not affected by this error; only the ice maker is disabled. It is safe to continue using the refrigerator for food storage while the repair is pending. However, ice production will remain unavailable until the sensor fault is resolved.

A reset may temporarily clear the error code from the display, but the fault will return if the underlying problem has not been corrected. The error is triggered by an out-of-range sensor signal, so the code will reappear as soon as the control board polls the sensor again. A permanent resolution requires diagnosing and repairing the sensor, wiring, or connector as indicated by the voltage test at CN90.

A knowledgeable DIYer can attempt this repair by first checking the wiring connector at the main PCB CN90 position for a loose or corroded connection, which sometimes resolves the error without replacing any parts. If the connector is secure and the voltage measurement at CN90 is outside the 1.0V to 4.5V range, the sensor or harness will need to be replaced. Working inside a refrigerator does not involve high-voltage hazards at the sensor level, but accessing the main PCB requires care around other board components.

If the fix is simply reseating a loose connector, there is no parts cost. Replacing the ice maker temperature sensor typically costs between $20 and $60 for the part, while a full Ice Bites ice maker assembly replacement can range from $80 to $200 or more depending on the model. Professional labor charges generally add $100 to $250 on top of parts costs, depending on your region and the technician's rates.
