Samsung Refrigerator Error Code Low Voltage

The Low Voltage error means the compressor inverter board has detected that the input voltage is below the acceptable level needed to safely operate the compressor. The inverter LED blinks to signal this fault. It can be caused by a weak power supply from the home circuit, a faulty inverter PCB, or in some cases a failing compressor.

Continuing to run the refrigerator with a Low Voltage fault is not recommended. If the compressor is running under insufficient voltage, it can overheat or sustain damage over time. The fault protection built into the inverter board exists specifically to prevent this, so persistent blink faults should be addressed promptly to avoid more costly repairs.

Repair costs vary depending on the root cause. If the issue is simply a wiring or outlet problem, costs may be minimal. Replacing the inverter PCB typically runs between $150 and $350 including parts and labor. Compressor replacement is significantly more expensive, generally ranging from $400 to $800 or more depending on the model and service rates in your area.

Some causes are DIY-friendly, such as checking the wall outlet voltage with a multimeter, inspecting the power cord for damage, or ensuring the refrigerator is on a properly rated circuit. However, replacing the inverter PCB or compressor requires comfort with appliance disassembly and working around electrical components. If you are not experienced with these repairs, a qualified technician is recommended.

A power reset may temporarily clear the blinking LED, but if the underlying cause such as low supply voltage or a faulty inverter board is not corrected, the error will return. Resetting is useful for confirming whether the fault is intermittent or persistent, but it is not a fix on its own.
