Samsung Refrigerator Error Code F Comp Low Voltage Error

This error code means the freezer compressor is receiving AC input voltage at or below 106 volts, which is below the minimum required for safe operation. The refrigerator's control system triggers this code to protect the compressor from damage caused by low-voltage conditions. It indicates a problem with the power supply to the refrigerator rather than a compressor failure in most cases. Checking the voltage at the wall outlet is the correct first step.

Resetting the refrigerator by unplugging it for a few minutes may temporarily clear the error code, but the code will return if the underlying low-voltage condition is not corrected. The control system will continue to detect the low input voltage each time the compressor attempts to operate. A reset is not a fix; it only clears the stored fault without addressing the root cause.

If the issue is with your home's electrical supply, costs can range from minimal outlet repairs to several hundred dollars for panel or wiring work performed by an electrician. If the refrigerator's power cord is the cause, replacement cords typically cost in the range of $20 to $60 for parts, plus labor if professionally installed. In cases where the main control board is faulty, board replacement parts alone can range from $100 to $300 or more depending on the model, with additional labor costs if a technician is needed.

Start by measuring the AC voltage at the wall outlet using a multimeter. If the voltage reads 106 volts or lower, the issue is with your home's electrical supply and may require an electrician to inspect the circuit, panel connections, or utility service. Make sure the refrigerator is plugged directly into a grounded wall outlet and not through an extension cord or power strip. If the outlet voltage is normal but the error persists, the refrigerator's power cord or main control board may need inspection.

The error itself represents a protective response by the refrigerator, so it is not immediately dangerous in terms of electrical safety for the user. However, persistent low voltage can cause the compressor to overheat and fail if the protective shutoff does not engage reliably. The underlying electrical issue causing the low voltage, such as loose wiring or a faulty circuit, could present a broader electrical hazard and should be evaluated by a qualified electrician.
