Samsung Refrigerator Error Code Sparkling Sensor Error

The Sparkling Sensor Error means the refrigerator's control board cannot get a valid reading from the temperature sensor in the sparkling water system. The board expects a sensor voltage between 1.0V and 4.5V at connector CN32 pins 1 and 3. If that voltage is missing or out of range, the board flags this error. The root cause is usually a loose connector, damaged wiring, or a failed sensor.

This error relates specifically to the sparkling water module and does not directly affect the main refrigerator or freezer compartments. Food safety is not an immediate concern, but the sparkling water function will be impaired. It is still worth addressing promptly to prevent the issue from spreading to other components or worsening a wiring fault.

A power reset may temporarily clear the error code from the display, but if the underlying fault in the sensor circuit is still present, the error will return once the board runs its diagnostics again. A reset alone does not fix a loose connector, damaged wire, or failed sensor. The physical cause must be identified and corrected for the error to stay cleared.

A knowledgeable DIYer can start by checking that the connector at ASSY KIT PCB CN32 is fully seated and that the wire harness shows no visible cuts or pinching. Verifying the voltage at CN32 pins 1 and 3 requires a multimeter and some comfort working near live circuits. If the problem is a failed sensor or damaged harness, those repairs involve part replacement and may be better handled by a technician.

Repair costs vary depending on the failed component. A replacement sparkling sensor typically falls in the range of $20 to $60 for the part alone. If a wire harness or the ASSY KIT PCB needs replacement, parts costs can range from $50 to $200 or more. Adding professional labor will increase the total, generally putting a full repair somewhere between $100 and $350 depending on what is found.
