Samsung Refrigerator Error Code R Comp Over Voltage Error

This error means the refrigerator's compressor circuit has detected an AC input voltage at or above 310V, which is beyond the safe operating range for the compressor. The refrigerator stops compressor operation automatically to prevent damage. It is a protective fault triggered by the inverter control system monitoring incoming line voltage.

You should not attempt to bypass or ignore this error, especially if your outlet voltage is actually elevated. High voltage can permanently damage the compressor and inverter board and may create an electrical hazard. Leave the refrigerator unplugged until the power supply issue is identified and resolved.

Repair costs vary depending on the root cause. If the issue is a high utility voltage or wiring problem, electrician fees typically range from $75 to $250 or more depending on the work required. If the compressor inverter control board needs replacement, parts and labor can range from $150 to $400 or higher. If the compressor itself was damaged by sustained over-voltage, replacement costs can be significantly higher, making a professional diagnosis important before committing to repairs.

Start by measuring the voltage at the wall outlet using a true RMS multimeter. If the voltage is abnormally high, contact your utility company or a licensed electrician before using the refrigerator again. If the voltage is normal, try resetting the refrigerator by unplugging it for a few minutes. If the error returns despite normal outlet voltage, the inverter control board may need to be inspected or replaced by a technician.

A power reset by unplugging the unit for several minutes may clear the error if the fault was caused by a temporary voltage spike that has since resolved. However, if the underlying cause, such as high utility voltage or a wiring problem, has not been corrected, the error will return. Always confirm your outlet voltage is within normal range before resetting and restarting the refrigerator.
