Samsung Refrigerator Error Code R-10 (Pantry-Sensor)

The R-10 error indicates a fault with the pantry room temperature sensor. It triggers when the sensor reports a temperature above 149°F (65°C) or below -58°F (-50°C), which signals a problem with the sensor itself, its wiring, or the connector at the main PCB. Possible causes include sensor disconnection, a short circuit, housing separation, or a failed sensor component.

A reset may temporarily clear the R-10 code, but if the underlying sensor or wiring fault is still present, the error will return. The code is triggered by an out-of-range voltage signal at the main PCB, so the physical cause must be corrected before the error clears permanently.

Repair costs depend on which component has failed. A pantry temperature sensor replacement typically falls in the range of $20 to $80 for the part, with additional labor costs if a technician performs the repair. A main PCB replacement is considerably more expensive, generally ranging from $150 to $400 or more for parts alone. Getting the wiring and sensor diagnosed first can help avoid unnecessary part replacements.

Some causes of the R-10 error are DIY-friendly. Start by checking the wiring harness and connector at main PCB CN30 pins 8 and 9 for loose or corroded contacts. If you have a multimeter, confirm the voltage at those pins falls between 1.0V and 4.5V. Replacing the pantry sensor is a moderate repair that many experienced DIYers can complete, though a faulty main PCB requires more advanced diagnosis.

The pantry compartment may not maintain its set temperature correctly while the R-10 error is active, since the control board relies on sensor feedback to regulate cooling. Food stored in the pantry section could be at risk if the compartment loses temperature control. It is best to address the fault promptly rather than continuing to use the unit in this condition.
