What the F Comp Over Voltage Error error code actually means

This error means your Samsung refrigerator detected that the electrical voltage coming from your wall outlet is too high, which could damage the freezer's compressor. The refrigerator shut itself down as a safety measure to prevent a more serious and costly breakdown. You should check whether the outlet is supplying normal household voltage before doing anything else.

Questions people ask about F Comp Over Voltage Error

What does F Comp Over Voltage Error mean on a Samsung refrigerator?
The F Comp Over Voltage Error means the refrigerator's control system detected that the AC input voltage reaching the freezer compressor has reached 310 volts AC or higher. This is above the safe operating range for the compressor and its inverter drive components. The refrigerator shuts the compressor down automatically to prevent damage. The first step is to measure the voltage at the wall outlet using a multimeter.
Will resetting my Samsung refrigerator clear the F Comp Over Voltage Error?
A power reset may temporarily clear the error code, but if the underlying over-voltage condition at the outlet still exists, the fault will return once the compressor attempts to restart. You need to resolve the actual voltage supply problem first. Simply resetting the unit without correcting the cause will not result in a lasting fix and may expose the compressor to repeated damaging voltage levels.
How much does it cost to repair a Samsung refrigerator showing the F Comp Over Voltage Error?
Repair costs vary widely depending on the root cause. If the problem is at the electrical supply, an electrician's service call typically runs in the range of $100 to $300 or more depending on the scope of work. If the inverter control board inside the refrigerator has been damaged and needs replacement, parts and labor costs can range from $200 to $600 or higher. Addressing the voltage issue early, before internal components fail, generally results in lower overall repair costs.
Is it safe to keep using my Samsung refrigerator when this error appears?
You should not attempt to bypass or ignore this error. An over-voltage condition above 310V AC can damage the compressor's inverter board and motor windings, leading to a much more expensive repair. Continuing to operate the refrigerator under an over-voltage condition also poses an electrical safety risk. Address the voltage issue at the source before restoring the refrigerator to service.
How do I fix the F Comp Over Voltage Error on my Samsung refrigerator?
Start by measuring the AC voltage at the wall outlet with a multimeter. Normal household voltage in North America should be in the range of 110 to 120 volts AC for a standard outlet. If the voltage is significantly elevated, contact your utility provider or a licensed electrician to diagnose the supply issue. If the outlet voltage is normal and the error persists, the inverter control board inside the refrigerator may need to be inspected and potentially replaced.
