Samsung Refrigerator Error Code R Comp Low Voltage Error

The R Comp Low Voltage Error means the refrigerator's control board has detected that the AC input voltage powering the compressor has dropped to 106 volts or lower. This voltage level is insufficient for safe and reliable compressor operation. The code serves as a protective alert to prevent compressor damage from running under low voltage conditions.

The error itself is a protective feature, not an immediate hazard, but the underlying cause can be a concern. Persistent low voltage can stress the compressor motor and shorten its lifespan significantly. Loose wiring connections in the outlet or panel, which are a common cause of voltage drop, can also present a fire or shock risk and should be inspected and repaired by a licensed electrician.

If the issue is with your home's electrical supply or outlet, repair costs through an electrician typically range from around 100 to 400 dollars depending on what needs to be fixed. If the refrigerator's main control board is found to be faulty and requires replacement, parts and labor can range from roughly 200 to 500 dollars. In many cases, the fix is simply correcting the electrical supply, which keeps costs on the lower end.

Start by measuring the voltage at the wall outlet using a multimeter while the refrigerator is plugged in. If the voltage reads 106V or lower, the issue is with your electrical supply, and you should contact an electrician to inspect the circuit, outlet, and panel connections. If the outlet voltage is normal, the problem may lie with the refrigerator's control board or internal wiring, which would require further component-level diagnosis.

Unplugging the refrigerator and plugging it back in may temporarily clear the error code, but the code will return if the underlying voltage problem has not been corrected. A reset does not fix the root cause. The error will continue to appear as long as the compressor input voltage remains at or below 106V during operation.
