Samsung Refrigerator Error Code R-10 (Pantry-Damper-Heater)

The R-10 code indicates a fault in the pantry room damper heater circuit. The control board has detected an open circuit, short circuit, contact error, or physical disconnection in the heater that prevents ice buildup on the pantry damper. This heater is critical for keeping the damper free-moving so the pantry compartment receives proper airflow and temperature control.

A power reset may temporarily clear the R-10 code from the display, but if the underlying fault in the damper heater circuit has not been repaired, the code will return. The control board actively monitors the heater circuit and will re-trigger the error once it detects the same open circuit, short, or contact failure. A reset is useful for confirming whether the fault is persistent, but it is not a repair.

Repair costs depend on the specific failure. If only the connector or wiring needs attention, a service call from a technician may cost in the range of $75 to $200 for labor. If the damper heater assembly requires replacement, parts and labor combined typically fall in the range of $150 to $400, depending on the specific model and local labor rates. Diagnosing the fault first with a resistance measurement at CN91 will clarify whether parts are needed before committing to a repair.

Some causes of R-10 are DIY-accessible. If the issue is a loose or corroded connector at Main PCB port CN91, reseating or cleaning the connector may resolve it. However, accurately diagnosing the fault requires a multimeter to measure resistance between the Black and Brown wires at CN91, with a target reading of 145 ohms plus or minus 7 percent. If the heater element itself has failed, replacing the damper heater assembly requires disassembly of the pantry compartment interior and comfort with refrigerator component replacement.

The refrigerator may continue to operate with R-10 active, but the pantry compartment's temperature control can be compromised if the damper freezes in a fixed position. If the damper becomes stuck closed, airflow to the pantry zone stops and temperatures will rise. If it freezes open, the compartment may become too cold. It is advisable to address the fault promptly rather than continuing to use the pantry zone under those conditions.
