Samsung Refrigerator Error Code R-1 (R-FAN)

The R-1 (R-FAN) error code means the refrigerator has detected a problem with the fresh food compartment inner fan motor. The control board is not receiving a valid feedback signal from the fan, which can be caused by a loose or broken wire, a poor connector contact, or a failed motor. The code is the system's way of flagging that the fan may not be circulating air properly through the fresh food section.

You should address the R-1 error promptly. If the fresh food fan is not operating, air circulation in the compartment is reduced or stopped, meaning food may not stay at a safe temperature even if the compressor is still running. Short-term use while arranging a repair is generally acceptable, but monitor food temperatures closely and do not leave perishables unattended for extended periods.

Repair costs depend on the specific cause. If only a connector needs reseating or a wire harness needs replacement, parts costs are typically in the range of $15 to $60. A replacement fresh food compartment fan motor generally costs between $30 and $90 for the part. If the MAIN PCB is at fault, board replacement can range from $100 to $300 or more. Adding a technician's labor will increase the total, typically by $80 to $150 depending on your location.

Some causes of the R-1 error are DIY-friendly. Checking for ice buildup around the fan, inspecting the wiring harness for obvious disconnections, and reseating connectors at the fan motor and PCB require only basic tools and careful observation. However, testing voltage at the MAIN PCB connector CN75 requires a multimeter and comfort working near live electrical components, so if you are unsure, a qualified technician should perform that step.

A power reset may temporarily clear the error code display, but if the underlying fault with the fan motor, wiring, or feedback signal line is not corrected, the R-1 code will return. Resetting the unit is useful as a first step to confirm whether the fault is intermittent, but it is not a repair. The physical cause of the fan circuit fault must be diagnosed and resolved for the error to clear permanently.
